Geochimica et Cosmochimica Acta or GCA, established in 1950, is a semi-monthly, peer reviewed, scientific journal published by Elsevier. It is sponsored by the Geochemical Society and the Meteoritical Society. The post of Executive editor is currently vacant, following the retirement of Frank Podosek (Washington University, who served from 2000 to the end of 2011). This journal is published in English, French, and German. The publishing focus of Geochimica et Cosmochimica Acta is geochemistry, cosmochemistry, and meteoritics. The geochemistry focus encompasses both terrestrial and other planetary bodies. The interdisciplinary scope covers geology, chemistry, biochemistry, physics, astronomy, and other, specialized, professional disciplines. Topical coverage includes physical chemistry (e.g., gases, aqueous solutions, glasses, and crystalline solids), petrology (igneous and metamorphic), chemical processes (Earth's atmosphere, hydrosphere, biosphere, and lithosphere), geochemistry (organic and isotopic), meteoritics (includes meteorite impacts), and lunar science. Publishing formats include original research articles.
Iron-bearing minerals in sediments naturally reduce contaminant levels
(Phys.org) —The release of wastes associated with nuclear reprocessing from storage facilities into the underlying sediments and groundwater is an important environmental concern. Scientists working with ...
An experiment recreates the crust of the moon Europa
Water, salts and gases dissolved in the huge ocean that scientists believe could exist below Europa´s icy crust can rise to the surface generating the enigmatic geological formations associated to red-tinged ...
Iron-bearing minerals in sediments react with and immobilize contaminants
The release of wastes associated with nuclear reprocessing from storage facilities into the underlying sediments and groundwater is an important environmental concern at the Hanford Site. This study provides ...
New formula for fast, abundant hydrogen production may help power fuel cells
Scientists in Lyon, a French city famed for its cuisine, have discovered a quick-cook recipe for copious volumes of hydrogen (H2).
Amber provides new insights into the evolution of the Earth's atmosphere
An international team of researchers led by Ralf Tappert, University of Innsbruck, reconstructed the composition of the Earth's atmosphere of the last 220 million years by analyzing modern and fossil plant ...
Potential solution to meteorite mystery: Chondrules may have formed from high-pressure collisions in early solar system
(Phys.org) —A normally staid University of Chicago scientist has stunned many of his colleagues with his radical solution to a 135-year-old mystery in cosmochemistry. "I'm a fairly sober guy. People didn't ...
Earthworms could help scientists 'dig' into past climates
A team of UK researchers believe earthworms could provide a window into past climates, allowing scientists to piece together the prevailing weather conditions thousands of years ago.
Magnetic rocks aid oil exploration
A new study has pinpointed the relationship between oil reservoirs and magnetic rocks, which could lead to more accurate oil exploration.
Studying meteorites may reveal Mars' secrets of life
In an effort to determine if conditions were ever right on Mars to sustain life, a team of scientists, including a Michigan State University professor, has examined a meteorite that formed on the red planet ...
Power behind primordial soup discovered
(Phys.org) —Researchers at the University of Leeds may have solved a key puzzle about how objects from space could have kindled life on Earth.
Impact craters may have been cradles of life
(Phys.org)—Even comparatively small meteorite impact craters may have played a key role in the origin and evolution of early life on Earth, according to a researcher at The University of Western Australia.
Hawaiian Islands are dissolving, study says
(Phys.org)—Someday, Oahu's Koolau and Waianae mountains will be reduced to nothing more than a flat, low-lying island like Midway.
Life from Mars could have 'polluted' Earth: Krauss
Unless you've been living under a rock—Earth or Martian—in the past month, surely you have heard about the Curiosity rover's landing and early adventures on Mars.
Unusual reaction eschews high temperatures and water to lock carbon dioxide away
(Phys.org) -- When it comes to reducing the impact of the energy we use to cool our homes and power our computers, one option is to remove gaseous carbon dioxide (CO2), pump it into underground reservoirs ...
