@Witsgeochem Yes, " Osmotic power".

When freshwater and seawater are mixed together, like when a freshwater river flows into the ocean, enormous amounts of energy are released. #geochemchat

It relies on a combination of activated magnesite, softeners and reverse osmosis to recover valuable minerals at different stages of the process.

The CSIR’s quest to find a better cleaning technology to curtail the impact of Acid Mine Drainage on the environment resulted in the development of a treatment technology called magnesite softening reverse osmosis. #geochemchat. Check this article: https://t.co/xg8DfWBXDb

Check this interesting article where researchers investigate dust particles and use Lead isotopes in the dust to trace historical lead sources. #geochemchat https://t.co/ni1QW4MTbS

If humans continue to release carbon into the atmosphere, many methods of radiocarbon dating will no longer be viable, and will not be able to provide absolute dates for artifacts up to 2,000 years old. Please check the article for more info. https://t.co/VuPR2aa7XR

#geochemchat. We have been talking about radiocarbon dating since the beginning of our course, we talked about it being better and reliable. The attached article is saying that,

“Rhisotope Project partners” are testing whether injecting harmless amounts of radioactive isotopes into the horns of living rhinos will make them unattractive to poachers by making them detectable when crossing international borders, as well as less desirable to buyers

[Wits Honours Geochemistry @Witsgeochem]

An interesting idea💡 Could radioisotopes be used to combat rhino poaching in South Africa? 🦏 #geochemchat

Radiocarbon dating can be used to determine when an earthquake occurred, however inaccuracies can arise. Check out this article on improving the dating of earthquakes through the use of tree rings and radiocarbon dating.

The processes that created Earth's first continents and the timescales over which they formed are debated. Check out this article and apply your knowledge. #geochemchat #geochemitsry https://t.co/DLxbqDCiOp

@Witsgeochem One problem with this approach to dating rocks and minerals on Earth is the presence of the rock cycle. To get around that, scientists have looked elsewhere in the solar system for even older rock samples.

[Daguy @Daguyinchem]

@Witsgeochem By determining the age of rocks. The age of rocks is determined by radiometric dating, it looks at the proportion of two different isotopes in a sample. Radioactive isotopes break down in a predictable amount of time, enabling geochemist/geologist to determine the age of a sample
