Hyrax middens are high-resolution climate records trapping organic matter datable using 14C. Funding from @nyuniversity's Climate Change seed grant allows the Boomplaas project to sample nearby middens. Here @The_Palaeolab introduces hyrax midden survey techniques to SA students.

Archaeological article describes two women buried close together in a 7th-9th century English graveyard, with isotopic results indicating possible childhoods in southern Europe or North Africa.

Me, very simple: ::awed whisper:: "Medieval lesbians from Africa!" 😮😊

Check out this article where isotopic ratios are used to enhance the understanding of the formation of hydrothermal and magnetic core deposits

Check out this article where isotopic data is used to draw conclusions on the differentiation of magma types of Skye. https://t.co/wEP9nSbguC. #geochemchat

Check out this article where the natural variation of Copper isotopes is determined by plasma-source mass spectrometry.

@greyling_wits @Witsgeochem True! I'll definitely check it out

Nuclear technology uses the decay of isotopes to generate electrical energy. Check out this article where energy obtained from Pu-238 decay powers satellites orbiting the Earth.

Excited about the (LA-ICP-MS) B-Isotope measurements that we recently carried out at @goetheuni (A. Gerdes). The goal is to better understand the processes that enrich #lithium and other #critical elements in magmatic-hydrothermal systems. @TUBergakademie @HZDR_Dresden @SppDome

@tsutsu1632 @radioac97960451 @Witsgeochem Pu-238 decay occurs naturally. Finances would only be required to harvest this energy release. It might be costly, but it would be a feasible way to combat energy shortages. I will check out the disadvantages of this process though.

[Rethabile @Rethabile2892]

@radioac97960451 @Witsgeochem It could really help with the Load Shedding crisis.

Isotopic & geochemical tracers are used to understand how confined aquifers undergo mineralization and salinization. Check out this article where stable isotopes show a direct saline intrusion from the sea, in comparison to underground water.

Check out this interesting article of how geochemists used sulfur isotopes to determine a baseline from which the fractionation of the Earth's crust began. https://t.co/JnN94g9nNB. @Witsgeochem #geochemchat

@Witsgeochem Scientists used the combination US-ESR age estimate obtained from teeth with U-Th age from palaeomagnetic analysis of flow stones. They managed to determine the depositional age of Homo naledi.

[Rethabile @Rethabile2892]

@Witsgeochem The earth's crust changes overtime. Scientists date the radioactive rocks embedded within the crust and thus they can determine the age of the Earth. #geochemchat

Check out this article that describes the methods used to compile radiocarbon database for the archeology of Mesoamerica. #geochemistry #geochemchat

[Pandora & IsoMemo @IsomemoPandora]

Happy to announce MesoRAD, a radiocarbon database for the archaeology of Mesoamerica (https://t.co/mCjjfjWaE8), which has been just published on @up_joad by @JA_Hoggarth, @c_ebert1 and Victor E. Castelazo-Calva (https://t.co/P2KEf20DfJ).
