Experiments cast doubt on theory of how Earth was formed

New geochemical research indicates that existing theories of the formation of the Earth may be mistaken. The results of experiments to show how zinc...

Insights into biogeochemical cycles based on glacial meltwater chemistry

Ph.D. student Lukasz Stachnik received funding from the Arctic Field Grant (AFG) in 2012 and 2013. He has, together with colleagues from HiSF and...

Moon is proto-Earth’s mantle, relocated

Measurements of an element in Earth and Moon rocks have just disproved the leading hypotheses for the origin of the Moon. Tiny differences in the...

Some islands started in diamond-bearing regions under continents, geochemists say

The raw materials of some volcanic islands are shaped by some of the same processes that form diamonds deep under the continents, according to...

Project maps the chemistry of the world’s oceans

Human actions are changing the oceans' chemistry. Pollution washes in from the coasts, iron-laden dust blows in from increasingly arid land, greenhouse gases raise...

Geochemical detectives use lab mimicry to look back in time

New work from a research team led by Carnegie's Anat Shahar contains some unexpected findings about iron chemistry under high-pressure conditions, such as those...

Oxygen key to containing coal ash contamination

As energy companies decide what to do with aging coal ash disposal facilities in North Carolina and across the nation, they may be overlooking...

Geochemists show experimental verification of principle of detailed balance

Geochemists at Indiana University and Virginia Tech have developed and demonstrated a technique for assessing the validity of a principle that has long been...

Cosmochemists find evidence of rare element in early solar system

University of Chicago scientists have discovered evidence in a meteorite that a rare element, curium, was present during the formation of the solar system....

A distant planet’s interior chemistry may differ from our own

As astronomers continue finding new rocky planets around distant stars, high-pressure physicists are considering what the interiors of those planets might be like and...
