@KLSDM23 @Tas_geochem Crocodiles are easier to locate at night by eyeshine. It is sometimes possible to catch them while they are basking during the day but you need to be quick! Most are caught in the water at night #geochemchat

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

More information about bioaccumulation, biomonitoring and bioconcentration. This study was done on coral reef food web.

"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.

For those who love Barium or Silicon (bio)geochemistry, please don't miss our recent publication in which we combined stable Ba and Si isotopes to understand the differing behaviors of barium and silicon at the continental margin.

Mediterranean cave clues show that islanders ingested mind-bending plants around 3,000 years ago. Analysis of hair strand found in this cave have provided Europe’s oldest direct evidence of psychoactive drug use #geochemchat

[Science News @ScienceNews]

Analyses of human hair found in a Mediterranean cave turned up psychoactive plant substances, revealing use of hallucinogens around 3,000 years ago.

More insight on how photoremediaion can be used to solve environmental problems such as pollution, reforestation, biofuels, and landfilling. #geochemchat

Nb is a very complex element. It's study of its speciation in solids is quite a challenge when it comes to geological analysis. Here is a techniques that has been developed to measure Nb minerals and synthetic oxides with geological relevance:https://t.co/jXiwKgqZhy

Interesting!! Project aims to understand the life history of the Speartooth Shark by quantifying the strontium and strontium isotope signatures of the Adelaide river #geochemchat

[Save Our Seas @saveourseas]

Researcher @Thesaltygeochem & supervisor Dr Brandon Mahan aim to better understand the life history of the Speartooth Shark, a rare river shark that occupies the Adelaide River.

University of Lausanne team has demonstrated that the phenomenon of iron oxidation occurred on Earth much earlier that previously thought. Techniques used behind this discovery: MC-ICP-MS and SIMS #geochemchat

[Faculté Géosciences et Environnement - UNIL @FGSE_UNIL]

Scientists at @unil have surprisingly observed traces of iron #oxidation in rocks dating from 3.8 to 1.8 billion years ago, well before what is known as the“Great Oxygenation Event ” What caused this oxidation? Bacteria? Oxygen? more info🌎👇@ElsevierNews https://t.co/FC1R2N5Aul
