Isotope Geochemistry

Geochemistry, 2020
We can broadly define two principal applications of radiogenic isotope geochemistry. The first is geochronology. Geochronology makes use of the constancy of the rate of radioactive decay to measure time. Since a radioactive nuclide decays to its daughter

The Impact of Geochemistry

Elements, 2015
As geochemists and mineralogists, we are well aware of the impact of our science. We can often reel off examples of how our discoveries have influenced industry and improved humankind's knowledge about how the Earth works, as well as how natural and anthropogenic processes have led to its present state.

Geochemistry of Impactites

Elements, 2012
Geochemical analysis is an essential tool for the confirmation and study of impact structures and the characterization of the various rock types involved (target rocks, impact breccias, melt rocks, etc.). Concentrations and interelement ratios of the platinum-group elements, as well as the osmium and chromium isotope systems, allow quantification of ...

The Carbonate Geochemistry of Enceladus' Ocean

Geophysical Research Letters, 2020
The plume composition at Enceladus contains clues about conditions and processes in the interior. We present new geochemical interpretations of Cassini mass spectrometry data from the plume gas and salt‐rich ice grains.
