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.
An asteroid smashing into a planet can dramatically alter the planet's habitability by setting back evolution or even encouraging biodiversity.
Dartmouth College researchers are shedding light on the early chemical reactions in the organic sediments that would ultimately become the Marcellus Shale, a major source of natural gas and petroleum.
How acidic is the ocean on Saturn's icy moon Enceladus? It's a fundamental question to understanding if this geyser-spouting moon could support life.
A Florida State University student has cracked the code to reveal the deep and interesting history of an ancient meteorite that likely formed at the time our planets were just developing.
Geochemists from Trinity College Dublin's School of Natural Sciences may have found a solution to a long-debated problem as to where - and how - life first formed on Earth.
University of Wyoming scientists have found evidence of continental collisions in Wyoming's Teton Range, similar to those in the Himalayas, dating to as early as 2.68 billion years ago.
Approximately 790,000 years ago, there were multiple cosmic impacts on earth with global consequences. Geoscientists from Heidelberg University reached this conclusion after dating so-called tektites from various parts of ...
Fracking has not contaminated groundwater in northwestern West Virginia, but accidental spills of fracking wastewater may pose a threat to surface water in the region, according to a new study led by scientists at Duke University.
Within the deep strata of the San Telmo "acid pit lake" in southwestern Spain rests a wealth of rich geochemical knowledge. That knowledge recently helped researchers at Penn State discover new information about the chemical ...
Ancient Earth might have had an extraterrestrial supply of vitamin B3 delivered by carbon-rich meteorites, according to a new analysis by NASA-funded researchers. The result supports a theory that the origin of life may have ...
