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 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 evidence that ...
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.
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 resins. The results ...
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, and have it become ...
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.
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 more than a billion ...
