Zircon wouldn’t lie about its age, right? 🤔 Our experiments reveal #zircon modified by melt can become a hot mess overnight & that U-Pb ages are potentially meaningless! Dang! 😬 New paper led by Jeremy Asimus @IMASUTAS @AntarcticSciAus @Macquarie_Uni onlinelibrary.wiley.com/doi/…
Experimental Replacement of Zircon by Melt‐Mediated Coupled Dissolution‐Precipitation Causes...

Experimental Replacement of Zircon by Melt‐Mediated Coupled Dissolution‐Precipitation Causes...

Zircon geochronology provides critical information on the rates and durations of geological processes and enables researchers to explore deep time. However, some zircon datasets show a continuum of...

Stoked to have been awarded a #DECRA #DE25 fellowship where I'll look at the interplay of tectonics and climate on critical minerals in deep time. Grateful to my mentors, collaborators and the small but mighty geo community in Tas for helping me get here! @UTAS_

These are amazing! Is there likely to be an Archean or Cambrian poster anytime soon?

Great to see discussion on expanding the critical minerals list in Aus. We're going to need a lot more than what's on the official list to make the renewable energy technology needed to achieve net zero, especially Copper and Nickel abc.net.au/news/2023-10-10/c…
To the untrained eye it looks like any ordinary rock, but what it can produce is 'critical' to our...

The race towards to a clean energy future is driving a momentous increase in demand for critical minerals. But just what those minerals are in Australia is up for debate — and it will have a major...

Meet Dr Lejun Zhang - an economic geologist at @utas_ 🧗🏾 He studies the formation process of ore deposits and helps to develop efficient exploration tools that contribute to a more sustainable minerals and resource industry. Awesome work Lejun! @sciencetasmania
