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.

Scientists discover ancient seawater preserved from the last Ice Age

Twenty thousand years ago, in the thick of an Ice Age, Earth looked very different. Because water was locked up in glaciers hundreds of feet thick, which stretched down over Chicago and New York City, the ocean was smaller—shorelines ...

Agrochemists find proof of the ferrous wheel hypothesis

A team of agrochemists from Russia, Germany, and Chile confirmed the so-called ferrous wheel hypothesis—the turnover of iron in the soil that enriches it with organic nitrogen. The results of the study were published in ...

Subglacial weathering alters nutrient cycles in Greenland

The nutrient cycles that underpin how carbon is stored and released from two of Greenland's glaciers is significantly affected by subglacial weathering, a new study has found, shedding further light on the geochemistry of ...

Extra-terrestrial Hypatia stone rattles solar system status quo

In 2013, researchers announced that a pebble found in south-west Egypt, was definitely not from Earth. By 2015, other research teams had announced that the 'Hypatia' stone was not part of any known types of meteorite or comet, ...
