Strontium isotope detection is tricky as no characteristic high energy ray emission is present. Fluorogenic natural due - Thioflavin T- is used to detect strontium as when exposed to strontium there is a change in fluorescence intensity.

An interesting read on how volcanos could be the origin of nitrogen for biological use and the origin of life. #geochemchat

[Science News @ScienceNews]

Millions of years ago, giant volcanic eruptions in what’s now Turkey and Peru deposited millions of metric tons of nitrate on the surrounding land.

@LWGChem The timescale will only go as far back as that colony of Hyrax's were present which is a relatively short timescale. A more detailed explanation of N-isotopes which dives deeper into plant and soil based Nitrogen isotopes can be found at: https://t.co/RqzExZPjdz #geochemchat

Stable Nitrogen isotopes can be used as a historical tracker of the type of food consumed by an organism. N levels will increase as you move up a trophic level. With change on climate organisms diet will alter and then so will the N isotope levels.#geochemchat

Millennia of a rodentlike animal’s urine preserve crucial data on climate. https://t.co/35foZcJyyk

@Witsgeochem Carbon isotopes relate to vegetation eaten by hyrax's which can be related to rainfall in the area. Nitrogen isotopes in hyrax middens are related to rainfall with low N concentrations relating to low rainfall #geochemchat

Lead contaminated Algae movement could contribute to pollution of water bodies
The algae will adsorb lead, get moved over the water to a new location, and when the algae dies the lead could be deposited back into the water column.

Check out Elora’s awesome project comparing effects of groundwater sampling techniques on analytical results. Thank you @TNQDroughtHub for supporting Elora’s work in @JCUGeoscience at @jcu 🤙🏝💦🧪

@KayGee_Sci Would ocean acidification have an effect on analysis of corals, as corals are seneitive to Ph and will dissolve more rapidly in higher Ph environment?

@Witsgeochem Cyclones can also be a cause of mass movement of soil, and can cause mass erosion and weathering over a large area. By analyzing these direct effects of the cyclone a history can be determined

An interesting article showing an novel idea for a method to track historical tsunamis via their heavy mineral sediment deposits on land. Unfortunately the deposits are eroded too easily to identifiy historical tsunami events. #geochemchat

The link between how minerals form on coral features and obtaining reliable geological records of changes in oceanic composition overtime. #geochemchat

Nano mesh could be the next breakthrough for aquatic cleanups of oil spills. This mesh can also degrade oils using photosensitive dies.

An article that identifies the source of magma supply for arc volcanos by analyzing Pb and Sr isotopic composition of ash in the area. It was determined that there ads no mantel processes involved with magma supply to the volcano.

@KayGee_Sci What about the burning of landfills contributing to the levels of pollution in streams?

An article on how ammonia levels can be tracked in real time in soil samples in the field. Ammonia levels are critical to both flora and fauna health, so being able to accurately determine their concentration is extremely helpful.#geochemchat
