The sulphur stable isotope composition of water in coal mines is often stratified, enriched with 34S at depth. Simple pyrite oxidation cannot explain this phenomenon.

Using forensic chemical methods to identify molecules of incomplete burning scientists find organic geochemical evidence of human-controlled fires in europe dating back to over 250 thousand years ago #geochemchat https://t.co/4783BsuOct

Seems like we need to be careful with our deep-time #CO2 reconstructions based on #carbon isotopes. https://t.co/lOP42J35VI

@TinyikoNovela @Obsidian211 AMS is distinct from conventional Mass Spectrometry because it accelerates ions to extremely high energies compared to the thousands of electron volts in MS, allowing for AMS to resolve ambiguities that arise in MS due to atomic and molecular ions of the same mass.

Fascinating detailed #geochem study @AGU_GCubed into the oxygen #isotope variability in cherts deposited at the ocean floor! Turns out we have to be careful interpreting these measurements for #paleoclimate reconstructions...

Funny enough, Mars volcanic geochemical character has been shown to differ from earth. K and Th are radioactive markers at volcanoes, as they emit gamma rays. However K and Th are found in very low amounts on Mars, the suspicion is a depletion over years of eruption. #geochemchat

A few sorts of decay include transmutation, where the parent isotope decays and yields a daughter isotope of a diverse component. In other sorts of decay, the nuclear number and component character of the parent and daughter are the same.

Analysis of PFAS present in blood samples. This is a helpful study as PFAS are forever chemicals, so its exposure levels can be determined, along with its effects and how this can be mitigated.
