  • Are Ants the Answer to CO2 Sequestration?

    GSA press release ^ | 7/29/2014 | Staff
    Boulder, Colo., USA – A 25-year-long study published in GEOLOGY on 14 July provides the first quantitative measurement of in situ calcium-magnesium silicate mineral dissolution by ants, termites, tree roots, and bare ground. This study reveals that ants are one of the most powerful biological agents of mineral decay yet observed. It may be that an understanding of the geobiology of ant-mineral interactions might offer a line of research on how to "geoengineer" accelerated CO2 consumption by Ca-Mg silicates. Researcher Ronald Dorn of Arizona State University writes that over geological timescales, the dissolution of calcium (Ca) and magnesium (Mg) bearing...

    YELLOWSTONE NATIONAL PARK - The world’s authority on Yellowstone’s Super Volcano says it’s more than twice as big as scientists once thought. Does that mean it’s more likely to blow up soon? Penny Preston found Dr. Robert Smith at his home near Grand Teton, and found the answer. Millions of people visit Yellowstone each year to see its geysers, fumeroles, hot springs, and mud pots. It’s the largest concentration of thermal features in the world. The park sits on top of the world’s largest active volcano. The Super Volcano. Its most recent eruption was more than 600,000 years ago. All...

    Science 2.0 ^ | 6/11/2014 | News Staff
    There have been times in our geological history when CO2 levels were 10X what they are today, yet warming was only slightly higher. Unlike what you often read in simplistic media accounts, there are a lot of variables in climate and weather and temperature. It takes a lot of things going wrong to turn Earth into Venus and we have never come close. At the Goldschmidt geochemistry conference in Sacramento, geochemists discussed one such period, but they say we just got lucky - a vast mountain range formed in the middle of the ancient supercontinent, Pangea.

    GIA: Gems and Gemology ^ | Winter, 2013 | Steven B. Shirey and James E. Shigley
    ABSTRACT It has been more than two decades since diamond ages have proven to be up to billions of years older than their host magmas of kimberlite or lamproite. Since then, there have been significant advances in the analysis of diamonds and their mineral inclusions, in the understanding of diamond-forming fluids in the mantle, and in the relationship of diamonds to the deep geology of the continents and the convecting mantle. The occurrence of natural diamonds is remarkable and important to earth studies. This article reviews current thinking of where, how, when, and why natural diamonds form.

The findings, reported in the journal Geology, indicate the mineral stevensite, which is found on both Earth and Mars, can be created either in hot, highly alkaline volcanic lakes, or by mineralisation in living microbes. Stevensite is a magnesium-silicate mineral, used a Nubian beauty treatment for several centuries.

It is now recognized to be a single volcano - instead of a volcano complex with multiple vents. Tamu Massif has a footprint that covers more area than any other volcano - about 120,000 square miles (310,800 square kilometers) - an area about the size of New Mexico. It also has a larger mass than any other known single volcano on Earth. How could this enormous volcano have...

    New Scientist ^ | Jeff Hecht
    LONG before evolution on Earth kicked in with a vengeance, it seemed to stall completely. From 1.7 billion years ago, for a billion boring years, Earth remained a slimy, near-static world of algae and microbes. The pace picked up 750 million years ago: glaciers spread, complex animals appeared, and by 520 million years ago the Cambrian revolution – an explosion of varied life – was under way. The reason for that long stasis has been a mystery. We may now have the answer: the gradual cooling of the planet's interior. Just as turning down a stove burner slows the boiling...

    The beer will be called Bone Dusters Paleo Ale (Hardy har har [Okay, actually, "paleo ale" is pretty good]). The yeast come from the surface of one of the oldest marine mammal fossils ever discovered in the western hemisphere. The idea for the beer came from Jason Osborne, who co-directs a nonprofit dedicated to advancing paleontology and geology. A paleo beer, Osborne thought, would be a great hook to interest non-scientists in fossils. I think many non-scientists are quite interested in fossils already, but I cannot argue against a paleo beer. Will whale-fossil beer really taste that different from other...

    Is the geological column a global sequence? by Michael J. Oard Creationist geologists are not yet agreed over whether the geological column represents an exact sequence of Flood events or not. Local stratigraphic sections seem to line up with the general order of the geological column at hundreds of locations around the world. But there are many problems with the details. For example, 1) the geological column is a vertical or stratigraphic representation abstracted from rock units that are mainly found laterally adjacent to each other in the field, 2) new fossil discoveries continue to expand fossil stratigraphic ranges, 3)...

Catalogued on his website Colorado Plateau Geosystems, these maps show the world adrift, its landscapes breaking apart and reconnecting again in entirely new forms, where continents are as temporary as the island chains that regularly smash together to create them, on a timescale where even oceans that exist for tens of millions of years can disappear leaving only the subtlest of geological traces. With a particular emphasis on North America and the U.S. southwest—where Blakey still lives, in Flagstaff, Arizona—these visually engaging...

    It's well known that the dinosaurs were wiped out 66 million years ago when a meteor hit what is now southern Mexico but evidence is accumulating that the biggest extinction of all, 252.3m years ago, at the end of the Permian period, was also triggered by an impact that changed the climate. While the idea that an impact caused the Permian extinction has been around for a while, what's been missing is a suitable crater to confirm it. Associate Professor Eric Tohver of the University of Western Australia's School of Earth and Environment believes he has found the impact crater...

Lead author Alicia Hotovec-Ellis, a UW doctoral student in Earth and space sciences, said that the extraordinarily high frequency of this tremor is not easily explained by many of the currently accepted theories. In fact, Redoubt’s volcanic wail reaches such a pitch it can be heard by human ears. “The pitch that Redoubt got up to was so much higher than any other volcano that...

    Pressure changes cause precious metal to deposit each time the crust moves. Scientists have long known that veins of gold are formed by mineral deposition from hot fluids flowing through cracks deep in Earth’s crust. But a study published today in Nature Geoscience1 has found that the process can occur almost instantaneously — possibly within a few tenths of a second. The process takes place along 'fault jogs' — sideways zigzag cracks that connect the main fault lines in rock, says first author Dion Weatherley, a seismologist at the University of Queensland in Brisbane, Australia. When an earthquake hits, the...

    Two kinds of sand ripples exist: normal, small ripples and megaripples with wavelengths reaching up to several meters. They differ also in their grain-size distributions (unimodal for sand ripples and bimodal for megaripples). While sand ripples form almost straight lines, megaripples have greater sinuosity due to their transverse instability, a property that causes small megaripple undulations to grow with time. The origin of the instability is due to variations in megaripple height, which do not diminish over time, as well as to the inverse dependence of ripple drift velocity on height. Thus, the taller regions of ripples will move more...

    Several people have become interested in a quite controversial topic called "AGENDA 21." They have requested being on a ping list for this topic. While I do not have time to do a thorough treatment of this subject, nor am I in any way an expert, I am willing at least for a time,to ping people as I run across articles which might pertain to this concern. It might be good to start with an examination of just what it is or might be. To kick this discussion and exploration off,I did a Google search (just for fun) on "Agenda...

    Researchers from the Wildlife Conservation Society have stumbled upon a geological colossus in a remote corner of Afghanistan: a natural stone arch spanning more than 200 feet across its base. Located at the central highlands of Afghanistan, the recently discovered Hazarchishma Natural Bridge is more than 3,000 meters (nearly 10,000 feet) above sea level, making it one of the highest large natural bridges in the world. It also ranks among the largest such structures known. "It's one of the most spectacular discoveries ever made in this region," said Joe Walston, Director of the Wildlife Conservation Society's Asia Program. "The arch...

    Wind is a much more powerful force in the evolution of mountains than previously thought, according to a new report from a University of Arizona-led research team. Bedrock in Central Asia that would have formed mountains instead was sand-blasted into dust, said lead author Paul Kapp. "No one had ever thought that wind could be this effective," said Kapp, a UA associate professor of geosciences. "You won't read in a textbook that wind is a major process in terms of breaking down rock material." Rivers and glaciers are the textbook examples of forces that wear down mountains and influence their...

    First before-after image (Google and GeoEye / March 12, 2011) Google on Saturday released its first satellite images of Japan since the devastation that followed a massive 8.9-magnitude earthquake and tsunami that hit the island nation Friday afternoon local time. The images, from Google partner GeoEye, were generated by the IKONOS satellite. Google Earth users may view images from Kamaishi, located to the north of Sendai, an area extremely hard hit by the quake and tsunami. In the images, taken Saturday morning, Kamaishi is somewhat obscured by cloud clover. In addition, Google released satellite images of Tokyo, also taken Saturday...

    A massive tsunami sweeps in to engulf a residential area after a powerful earthquake in Natori, Miyagi Prefecture in northeastern Japan March 11, 2011. The biggest earthquake to hit Japan in 140 years struck the northeast coast on Friday, triggering a 10-metre tsunami that swept away everything in its path, including houses, cars and farm buildings on fire. Cars and destroyed homes swept by a tsunami are seen on a street after an earthquake in Kesennuma City, Miyagi Prefecture March 12, 2011. Japan confronted devastation along its northeastern coast on Saturday, with fires raging and parts of some cities under...

    I'll do this a bit differently; click the image and go to where you can click on a bigger version. Text accompanying the first: Etretat is well known for its cliffs, including a famous natural arch, which some call "The needle's eye." These cliffs and the beach next to them, attracted many artists (Eugène Boudin, Gustave Courbet, Claude Monet). Étretat was the birthplace of Elie Halévy (1870-1937), philosopher and historian. In the French coast in the department of Seine-Maritime, Upper Normandy, are the spectacular cliffs of Etretat, only two hours from Paris by car. These are two views of the...
  • Arctic rocks shed light on ancient Earth's inner workings

    Geochemists studying Arctic rocks say they have found evidence of ancient rock from the interior of the Earth that is nearly as old as the planet itself. Such material gives scientists an idea of what the mineral structure of the inner Earth used to look like billions of years ago and may force them to adjust their theories about the evolution of the planet's structure over the eons, said Matthew Jackson, a geochemist at Boston University and lead author of the paper.
