Groundwater has better hydrogeochemical quality than surface water and was more favorable for human society utilization.

Soils serves as a sink for carbon, lessening the effects of climate change. Interestingly, microbes in soil store the most significant amount of carbon due to their efficient carbon use.

@GeochemTee @TinyikoNovela Thank you @GeochemTee . So AMS can detect the amount of radioactive carbon in samples. The main difference to MS is the energy of the acceleration of ions. So this then solves some of the gaps and uncertainties in MS due to atomic and molecular ions of the same mass.

Why thermochemistry matters. Beautiful application in #IJMS of electron photodetachment for isobar removal in accelerator #massspec because EA(AlO) > EA(MgO). @LabLaskin

"This gives a better understanding of why some dubduction zones fail while others set up as long term, steady-state systems" said Joshua Garber, assistant research professor of geoscience at Penn State.

Geochronometer uses radiometric dating which means they use the number of atoms of a known radioactive isotope and the number of daughter atoms produced when the radioactive isotopes decay. #geochemchat

A beautifully euhedral titanite xl in granodiorite from the Mt. Whitney pluton, CA.
Also known as sphene (if you're old school), titanite can be used as a geochronometer, to tell geologists the age of a rock!
