detecting water on Mars
2014-10-07 03:00:14

Provided by Eric Sorensen, Washington State University A Washington State University undergraduate has helped develop a new method for detecting water on Mars. Her findings appear in Nature Communications, one of the most influential general science journals. Kellie Wall, 21, of Port Orchard, Wash., looked for evidence that water influenced crystal formation in basalt, the dark volcanic rock that covers most of eastern Washington and Oregon. She then compared this with volcanic rock...

Ancient Rocks Provide Clues About Earth's Earliest Crust
2014-05-30 03:14:31

By Bryan Alary, University of Alberta PhD student's studies of four-billion-year-old rocks show ancient crust generated in an Iceland-like setting. It looks like just another rock, but what Jesse Reimink holds in his hands is a four-billion-year-old chunk of an ancient protocontinent that holds clues about how the Earth’s first continents formed. The University of Alberta geochemistry student spent the better part of three years collecting and studying ancient rock samples from...

Volcanic Rock Research Sheds New Light On Earth’s Formation
2013-11-08 12:29:31

redOrbit Staff & Wire Reports - Your Universe Online By analyzing basalt, a substance formed from cooling lava, a team of European scientists have gained new insight into how the Earth’s core, crust and atmosphere formed, as well as how volcanic activity originated. According to UPI, the researchers recreated the conditions of the Earth approximately 4.5 billion years ago, when much of the world was molten and the crust formed as lava cooled. Their goal was to develop a...

Scientists Uncover Link Between Lavas Erupting On Sea Floor And Deep-carbon Cycle
2013-05-03 08:05:27

Smithsonian Scientists from the Smithsonian and the University of Rhode Island have found unsuspected linkages between the oxidation state of iron in volcanic rocks and variations in the chemistry of the deep Earth. Not only do the trends run counter to predictions from recent decades of study, they belie a role for carbon circulating in the deep Earth. The team's research was published May 2 in Science Express. Elizabeth Cottrell, lead author and research geologist at the Smithsonian's...

A mysterious cycle of booms and busts in marine biodiversity over the past 500 million years could be tied to a periodic uplifting of the world's continents, scientists report in the March issue of The Journal of Geology. The researchers discovered periodic increases in the amount of the isotope strontium-87 found in marine fossils. The timing of these increases corresponds to previously discovered low points in marine biodiversity that occur in the fossil record roughly every 60 million...

Image 1 - Building Blocks Of Early Earth Survived Collision That Created Moon

Unexpected new findings by a University of Maryland team of geochemists show that some portions of the Earth's mantle (the rocky layer between Earth's metallic core and crust) formed when the planet was much smaller than it is now, and that some of this early-formed mantle survived Earth's turbulent formation, including a collision with another planet-sized body that many scientists believe led to the creation of the Moon. "It is believed that Earth grew to its current size by collisions...

The biological and geographical website EurekaMag.com publishes reviews of specific subjects of all areas of biological and geographical science. The latest insights cover Homo sapiens which are the only living species in the Homo genus, originated in Africa about 200,000 years ago and reaching full behavioral modernity around 50,000 years ago. The latest review is about the three main rock types Igneous Rocks, Metamorphic Rocks and Sedimentary Rocks. Mannheim, Germany (PRWEB) January 13,...

Diamonds Show Carbon Cycle May Reach Earth's Lower Mantle
2011-09-16 10:41:51

  By studying the chemistry of an unorthodox set of Brazilian diamonds, a team of researchers have discovered startling new information about the carbon cycle and the theory of plate tectonics. Researchers from the University of Bristol, Universidade de Brasilia, and the Carnegie Institution for Science studied what are known as "superdeep" diamonds, some of which originated from depths of 435 miles (700km) or more before erupting to the surface as volcanic rocks. Most diamonds...

HOUSTON, March 28, 2011 /PRNewswire/ -- Texas Rare Earth Resources Corp.(OTCQB:TRER) has completed analysis of 1103 drill samples from the 1984-88 drilling program conducted by Cabot Corporation and Cyprus Minerals. All or a portion of forty-six out of an estimated two hundred fifty existing drill holes have been re-logged and re-analyzed. The rare earth element and other metals are consistent with the original study by the Texas Bureau of Geology that was published in the Geological...

Garnierite is a mineral composed of hydrous nickel silicates a member of the serpentine group with formula: (Ni,Mg)3Si2O5(OH). Népouite is a synonym. Garnierite is important as a source of nickel and is mined from laterite deposits which are formed by intense weathering and secondary enrichment of ultramafic igneous rocks.
