Geochemistry used in a sentence

Geochemistry in a sentence as a noun

I'm a geochemistry PhD student working on volcanoes, but I have several website projects, of which climbshare. com is the most recent.

The same is true for deep-earth seismology and mantle geochemistry. A good new method is mapping the antineutrino flux from Earth.

Reminds me of one of my good friends from college, who bailed out in the second year of his PhD program in geochemistry and started anew in a MSc program in Computer Science. He now works happily in a startup company as a SDE and never looks back.

At location X, Scientist A finds some clues in plate tectonics, Scientist B finds something in geochemistry, and Scientist C finds something in fossil records. Then they piece them together and if these stories all tell the same thing without a serious conflict, you can construct a point on that map.

Only one reason I don't do any geochemistry or archaeology either, just produce boring old invoiceable paperwork.

So you have to correlate events, to find proxy signals like changes in water geochemistry and so on. This increases uncertainties when dealing with fossils, and may be an easy way to denigrate palaeontological studies, but there are still evidences of a progressive decline.

One of the elephant-sized gaps in our ability to model the climate is that we know our current understanding of subsurface oceanic geochemistry and geophysics is basically fiction, we are routinely surprised in this regard when we actually measure it. The measurements we've based models on have been extremely sparse relative to both the complexity and dynamics of the system.

The abstract clearly presents the question as an alternative, not "the only remaining possibility", as you stated: "PH3 could originate from unknown photochemistry or geochemistry, or, by analogy with biological production of PH3 on Earth, from the presence of life" It doesn't strike me as scientific to "ignore an unknown unknown", which would boil down to an assumption that we already know every possible reaction mechanism there is to know. Discovering unknown chemistry would be groundbreaking of course, but the same goes for confirming extraterrestial life.
