'Highway from hell' fueled Costa Rican volcano

If some volcanoes operate on geologic timescales, Costa Rica's Irazú had something of a short fuse. In a new study in the journal Nature, scientists suggest that the 1960s eruption of Costa Rica's largest stratovolcano was ...

Copper chains: Study reveals Earth's deep-seated hold on copper

Earth is clingy when it comes to copper. A new Rice University study this week in the journal Science finds that nature conspires at scales both large and small -- from the realms of tectonic plates down to molecular bonds ...

Mystery Solved: Marine Microbe Is Source of Rare Nutrient

(PhysOrg.com) -- A new study of microscopic marine microbes, called phytoplankton, by researchers at Woods Hole Oceanographic Institution (WHOI) and the University of South Carolina has solved a ten-year-old mystery about ...

Pumping draws arsenic toward a big-city aquifer

Naturally occurring arsenic pollutes wells across the world, especially in south and southeast Asia, where an estimated 100 million people are exposed to levels that can cause heart, liver and kidney problems, diabetes and ...

Meteorites' age is at center of Mars history debate

Planetary scientists dream of sending a geologist to Mars to study its rocks by hand. Until then, they have to settle for examining meteorites - chunks of the Red Planet that land on Earth after hurtling through space and ...

Aquatic microbe oxidizes iron minerals from the surface inward

(Phys.org) —When the water-dwelling microbe Sideroxydans lithotrophicus ES-1 connects with iron mineral particulates, three microbial proteins quickly extract electrons from divalent iron or Fe(II), leaving behind trivalent ...

Geochemistry

The field of geochemistry involves study of the chemical composition of the Earth and other planets, chemical processes and reactions that govern the composition of rocks, water, and soils, and the cycles of matter and energy that transport the Earth's chemical components in time and space, and their interaction with the hydrosphere and the atmosphere.

Some subsets of geochemistry are:

Victor Goldschmidt is considered by most to be the father of modern geochemistry and the ideas of the subject were formed by him in a series of publications from 1922 under the title ‘Geochemische Verteilungsgesetze der Elemente’ (geochemical laws of distribution of the elements).
