Archive Classic: The Mystery of the Ultra-Pure Sandstones

first_imgReprinted from June 27, 2003, this mystery is worth considering still. What caused these global deposits that are not being formed today?6/27/03 — R. H. Dott, Jr (Univ. of Wisconsin) has a problem.  He’s been trying to explain a geological puzzle for 50 years, and it is still unresolved.  All around the world, sandstones are found that are “remarkably pure” that “seem nonactualistic” (jargon for “They can’t really be there”).  These pure quartz arenites, as they are called, were considered a major puzzle half a century ago, when Dr. Dott was a student.  Some of them “extend laterally over vast areas encompassing one or several states,”  and they cover vast areas of Africa and Arabia, the Great Lakes region, South America, Australia, and more.  These “sheet sands” (as they are nicknamed) are part of a notorious gang: “Together with the origin of dolomite, red beds, black shale, and banded iron formation, they made up a group of seemingly intractable geological problems” (emphasis added in all quotes).Dott tells autobiographically, “Having lived literally upon quartz-rich sandstones for almost 50 years, I have come to regard supermature quartz arenites as nature’s finest distillate—almost as remarkable as a pure single malt Scotch whiskey.”  In the July 2003 Journal of Geology, he has written a lengthy paper addressing the mystery of the quartz arenites, and the status of current hypotheses.  It amounts to a veritable State of the Century address to sandstone geologists.  He explains the puzzle in the Introduction:What is the quartz arenite problem?  Foremost is the extreme compositional maturity of sandstones composed of more than 95% quartz.  Furthermore, the quartz consists almost exclusively of grains of unstrained, single-crystal units.  Very rare lithic [rock] fragments consist only of durable polycrystalline quartz types such as chert or vein quartz.  In addition, the extremely rare accessory mineral suite (generally <0.05% by weight) is dominated by durable zircon, tourmaline, ilmenite, and leucoxene.  Where present, associated conglomerates also consist only of durable clasts of vein quartz, quartzite, or chert.  How can we explain the complete disposal of at least 75% of any ultimate parent igneous or metamorphic rock to yield a residue that is at least 95% quartz sand? Extreme textural maturity is also characteristic of many, but not all, examples.  A high degree of sorting has always been emphasized, with high rounding being common but not universal.  Both properties imply much abrasion by one or more of nature’s most physically vigorous processes, such as surf and strong eolian [wind] or aqueous currents. Dr. Dott mentions additional puzzles about these formations:Thin, tabular geometry: layers tens or hundreds of meters thick, very flat over vast regions, yet Paleozoic in age – i.e., prior to the emergence of land plants.A paucity of associated shale, in contrast to other sandstones.Interstratified with shallow marine carbonate strata.A lack of volumetrically significant analogues forming today (i.e., nothing on that scale can be seen forming now).  This implies weathering processes orders of magnitude greater in the past.Very rare body fossils, and some burrows.Frosting of the grains, making them rough on microscopic scales.Underlying mature shale high in kaolinite (clay) or illite.Even more pure quartz arenites, up to thousands of meters thick, in Precambrian strata.Many of them underlain by paleosols (ancient soils) that show a high degree of chemical maturation.According to Dott, wind erosion is the most efficient, but not the only, agent for rounding of the sand grains.  Some geologists have resorted to theories of multicycling to explain the weathering and maturation of the grains, but theories of single cycles “under intense tropical weathering” also go back decades, and he cannot rule them out.  (Though there are small examples forming in isolated river deltas today, their grains are not nearly as rounded.)  The chemical maturation suggests that impurities were dissolved away, a process called diagenesis, but that is not possible in the presence of wind.The paradox of the compositional maturation of the sand “seems to require some additional factor to reconcile geomorphic conditions that could have enhanced the transport and abrasion of enormous volumes of pure quartz sand, on the one hand, but could have allowed exceptional chemical maturation of soils on the other hand, as indicated by profiles beneath, and the composition of pelitic [mud, clay] strata interstratified within, many quartz arenites.”Dott introduces his theory at this point.  To solve the paradox, he postulates thin microbial crusts or mats of cyanobacteria formed over the soils, similar to the stromatolites and cryptogamic soils seen forming in some regions today.  These might have protected the underlying paleosols while allowing wind transport of sand above.  The lack of trees and shrubs might have allowed much more energetic winds.  This assumes that the first land invaders were cyanobacteria, although “the fossil record has seemed mute” on this point.  In a sense, these crusts formed a cap that protected the lower strata while the high winds deposited the sand (although he does not propose sources for the sand).He ends with one other paradox; without land plants, unless the landscape were perfectly flat, how could it be stable enough to allow the chemical weathering of both the sand and underlying paleosols?  “The abundance of medium-grained to coarse-grained sand and associated pebbles required streams with sufficient gradients to transport such materials, which in turn points to at least moderate topographic relief, which exacerbates the stabilization problem,” he says.  His best guess, in conclusion, is the microbial mat theory; this formed a crust enough to stabilize the landscapes for up to two billion years while these puzzling structures formed. This was an interesting paper about an interesting puzzle that some readers may wish to investigate further.  Does his explanation satisfy you?  Notice how these formations are huge, and exist on every continent.  Notice how thick and flat they are.  Notice how they are interspersed with clays and soils, yet are exceptionally pure, “nature’s finest distillate.”  Notice how they give evidence of being deposited via nature’s most vigorous and energetic forces.  Doesn’t this sound like global cataclysm?  Since catastrophism is back in vogue, should we not follow the evidence where it leads?(Visited 830 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

Garth Brooks Visits Childrens Hospitals And Clinics Of Minnesota

first_imgFriday afternoon, Garth Brooks visited the St. Paul campus of Children’s Hospitals and Clinics of Minnesota to dedicate the Child Life Zone — a therapeutic play area for patients, siblings and families.The Children’s – St. Paul Child Life Zone was made possible through a partnership with Teammates for Kids, of which Garth is co-founder.In addition to the therapeutic craft and play area, the Child Life Zone offers a gaming and media wall, a performance space for in-house TV programming, kitchen area for special events, and toys, books and games for all ages. To help children more easily cope with their hospital experience, patients visiting the Child Life Zone also receive support from Child Life Specialists trained to help with the psychosocial needs of children in the health care setting. Sibling play services are also offered to kids whose brother or sister is in the hospital.As Garth was dedicating the Child Life Zone at Children’s – St. Paul, he said, “Child life is medicine that money can’t buy. Child life is a way of the future. The message is you’re never alone in your life no matter what, and always keep children first.”Teammates for Kids, which is made up of more than 3,900 professional athletes that share a common vision for helping children all over the world, focuses on helping children in the areas of health, education and inner-city outreach. The Child Life Zone at Children’s is the 11th zone across the U.S. sponsored by Teammates for Kids.“Being in the hospital can be a stressful experience for children and families, so it’s wonderful to have a kid-friendly, healing space like the Child Life Zone where families can relax and kids can be kids,” said Joy Johnson-Lind, MSW/LICSW, senior director of child and family services at Children’s.More than 100 patients are expected to visit the Children’s – St. Paul Child Life Zone each month, which is located on the third floor of Children’s St. Paul Campus, at 345 North Smith Avenue.last_img read more

Tableau goes Hyper to keep up with customers data needs

Explore further The Seattle company, which makes software to visualize analytics, is introducing its so-called Hyper engine in a software update Wednesday. The technology is designed to make the data-visualization process five times faster, meaning businesses can input millions of data points and see results in seconds.Businesses use Tableau to make sense of information about everything from auto-sale trends to health-care-product inventory. As data continues to get easier to collect and there is more to analyze, Tableau’s software needed to keep up. “It’s a natural and necessary product evolution,” Gartner analyst Cindi Howson said. “It keeps up with current demand, and it improves the satisfaction with existing customers to let them continue to do faster, more sophisticated analytics within Tableau.”The company has faced growing competition from a number of smaller rivals, as well as entrenched players such as Microsoft with its Power BI product. Adding Hyper should help Tableau bring in new large customers as well as keep its existing users satisfied as they grow, Gartner analyst Rita Sallam said. Gartner research shows Tableau ranks sixth in market share for the overall analytics software industry, but it holds the top spot in the more specific “modern BI platforms” industry, with 28.3 percent market share. The Hyper technology was developed by a team at the Technical University of Munich. Tableau acquired the company that they spun out, called HyPer, in March 2016. HyPer focused on allowing users to add more information at the same time that data was being analyzed and processed, without slowing anything down.Existing Tableau customers can upgrade to the newest version of the software whenever they want-it doesn’t cost more-and all data and tools should transfer over smoothly, said Tableau chief product officer Francois Ajenstat.That’s the main reason the company took 18 months to integrate Hyper into the Tableau software. It wanted to make sure that all tools and processes worked the same way with the new engine and there would be no glitches, he said.Tableau has been testing the new system since summer. Another advantage of Hyper is yet to come. It will serve as the basis for Tableau’s yet-to-be-released data-preparation product that will help companies get their data ready to be analyzed. Wednesday’s announcement of the Hyper integration could signal that this product, called Maestro while in development, will be released soon.

Reaching rural America with broadband internet service

Satellite broadband – where a customer has an antenna that connects with an orbiting satellite linked to a faster internet connection back on Earth – is technically available anywhere in the country. But it is slower, and often more expensive, than wired broadband connections. And its connections are vulnerable to bad weather.Radio connections can vary significantly. One type, called “fixed wireless,” requires customers to be within sight of a service tower, much like a cellphone. Speeds can be up to 20 megabits per second. Satellite broadband and fixed wireless are used mostly in rural areas, but account for less than 3 percent of the U.S. fixed broadband market.Other options just being explored involve frequency ranges that are newly available. An approach using “white space” signals would transmit data on channels previously used by analog television broadcasters. Its signals, like TV broadcasts, can travel several miles, and are not blocked by buildings.Another frequency range around 3.5 GHz, called “Citizens Broadband Radio Service,” could let rural internet companies use frequencies previously reserved for coastal radar – even in places far inland. But the FCC may be changing the rules to favor large telecommunications companies instead.Mobile wirelessThe fourth type of wireless internet is already quite widespread – it’s on people’s smartphones nationwide. Many people have higher-speed connections at home and use mobile data on the go. However, people who don’t have access to, or can’t afford, other internet service, often use mobile wireless service as their primary internet connection.U.S. wireless companies’ coverage maps can be deceptive. Just because a carrier has a cell tower along an interstate highway does not mean the rest of the surrounding county also has good coverage.In our group’s research trips to Maine in 2016 and 2017, four people had phones with four different carriers, but there were plenty of places where not a single cell service was working. We have heard tales of small towns that have acceptable signals only in very specific spots – like in the middle of a side street. Telecommunications wires stretch along a rural Kansas road. Credit: Technology & Information Policy Institute, University of Texas, CC BY-ND Citation: Reaching rural America with broadband internet service (2018, January 17) retrieved 18 July 2019 from https://phys.org/news/2018-01-rural-america-broadband-internet.html All across the U.S., rural communities’ residents are being left out of modern society and the 21st century economy. I’ve traveled to Kansas, Maine, Texas and other states studying internet access and use – and I hear all the time from people with a crucial need still unmet. Rural Americans want faster, cheaper internet like their city-dwelling compatriots have, letting them work remotely and use online services, to access shopping, news, information and government data. Technology is improving – why is rural broadband access still a problem? A related issue is that fewer rural Americans are online: 39 percent of rural Americans lack home broadband access – in contrast to only 4 percent of urban Americans. And 69 percent of rural Americans use the internet, compared to 75 percent of urban residents. That means less participation in the culture, society, politics and economic activity of the 21st century.Building a nationwide internet structureThe basic problem is that high-speed internet has not yet reached huge swathes of rural America. There are two main ways to fix this problem: with wires, and without wires. Smaller towns in rural areas typically have two options for wired connectivity. About 59 percent of all fixed broadband customers use internet provided by the local cable company. Another 29 percent get their internet over phone lines, often called digital subscriber line service, or DSL. However, older systems in rural areas aren’t upgraded as often, making them slower than those in metro areas.A few small rural towns have fiber optic networks that are much faster, but they are exceptions.One reason rural wired service is less available and less advanced is cost, which relates to population density. In urban communities, a mile-long cable might pass dozens, or even hundreds, of homes and businesses. Rural internet requires longer wires – and often special signal-boosting equipment – with fewer potential customers from whom to recoup the costs. Rural homeowners who complain to me that they can’t get DSL, but say the farm down the road can, are probably just a bit too far from the phone company’s networking equipment. That’s much less common in cities and towns.Wireless optionsCovering these longer distances may be easier with wireless technologies, including satellite broadband, short-distance radio links and mobile-phone data. This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. Mobile phone data service has different speeds, and is often priced by how much data and how fast it travels – though even plans labeled “unlimited data” may slow down traffic after a customer transmits or receives a certain amount. Many companies promote their fourth-generation, or 4G, networks for their potential download speeds of around 20 megabits per second. But 5 to 12 megabits per second may be far more common, especially in rural regions – making it more comparable to DSL. Mobile companies built massive networks to serve densely populated cities, leaving less populous rural markets without comparable improvements. Some hold out hope for the next wireless-data standard, the even faster fifth-generation 5G system – but rural America may not see that service for a while.Bringing high speeds to remote placesIn our work, we have found a lot of people on tight budgets figuring out how to use local Wi-Fi connections to download content onto their phones, so they use (and pay for) less mobile data. Public libraries, which generally have fast and free Wi-Fi, are popular options in rural areas. Many rural librarians have told us about people in their parking lots after hours simply using the library Wi-Fi. Those connections aren’t always the fastest, but are a testament to the efforts of public libraries over many years to provide their communities’ residents with computer and internet services.The policy debates in Washington provide the U.S. with the opportunity to choose to provide equal access to high-speed internet all across the country, or to relegate rural users to their smartphones, library parking lots and slow home connections. Real high-speed internet could change the lives of rural Americans: The FCC itself has reported that people use fixed broadband differently, and get more benefits from it than mobile data.Fundamentally, it is a question of values. In the 1930s and ’40s, the public sentiment was that the nation would be better off if everyone had reasonably comparable electricity and telephone service. As a result, the federal government established a system of loans and grants to ensure universal access to those key utilities. To help, the FCC set up a system to charge businesses and urban customers slightly higher fees to subsidize the higher costs associated with bringing phone lines to rural areas. The question facing the FCC and Congress – and really, the U.S. as a whole – is whether we are willing to invest in providing broadband service equitably to both urban and rural Americans. Then we need to make sure it is affordable. Provided by The Conversation National standards have not helped: As people, businesses and governments need and want to do more online, the FCC-set minimum data-transmission speeds for broadband service has climbed. The current standard – at least 25 megabits per second downloading and 3 megabits per second uploading – is deemed “adequate” to stream video and participate in other high-traffic online activities. But those speeds are not readily available in rural areas. The FCC is actually considering reducing the standard, which critics say may make the rural digital divide disappear on paper, but not in real life.Rural residents have few choices of internet service providers – or none at all. They pay higher prices for lower quality service, despite earning less than urban dwellers. Explore further This article was originally published on The Conversation. Read the original article. With an upcoming Federal Communications Commission vote on whether cellphone data speeds are fast enough for work, entertainment and other online activities, Americans face a choice: Is modest-speed internet appropriate for rural areas, or do rural Americans deserve access to the far faster service options available in urban areas?My work, which most recently studies how people use rural libraries’ internet services, asks a fundamental set of questions: How are communities in rural regions actually connected? Why is service often so poor? Why do 39 percent of Americans living in rural areas lack internet access that meets even the FCC’s minimum definition of “broadband” service? What policies, beyond President Donald Trump’s new executive orders, might help fix those problems? What technologies would work best, and who should be in control of them?The wide-ranging rural internet problemSince the dawn of the internet, rural areas of the U.S. have had less internet access than urban areas. High-speed wired connections are less common, and wireless phone service and signals are weaker than in cities – or absent altogether. Even as rural America’s wired-internet speeds and mobile-phone service have improved, the overall problem remains: Cities’ services have also gotten better, so the rural communities still have comparatively worse service. read more
