New OA paper: niobium-rich carbonatites in Australia formed ~830 Million years ago as Rodinia rifted. Multi-method geochronology + isotopes trace mantle melts funneled up long-lived faults = insights for Nb/REE exploration. doi.org/10.1017/S0016756825100204

Reviewing Earth’s earliest continental crust; exploring how internal tectonics and possible external forces, from impacts to astrophysical cycles, shaped the continents that underpin habitability.

Earth’s energy switch recorded in mineral grains
New research suggests Earth’s early crust stopped being powered mainly by giant asteroid impacts and started running on its own internal heat about 3.9 billion years ago. doi.org/10.1038/s432...

Check out this incredible cave system in the Tamala Limestone on Rottnest Island; sculpted by rhizoliths (fossilised root structures) and now a perfect hideout for Sand Tiger Sharks. WA’s geology rocks! More on Rotto’s geology here: doi.org/10.1111/bre....

Sand… deceptively simple, endlessly fascinating. Through geochronology and isotope fingerprinting, even a handful of beach sand can tell the story of mountains rising, continents colliding, and ancient rocks eroding. A whole world in a grain of sand. doi.org/10.1144/jgs2...

Just had a great visit to @UniofAdelaide where I had the chance to present on crustal evolution and impact processes, representing C-FIGS at Curtin. Really valuable discussions with the Earth Sciences team. #CFIGS #CurtinGeology #GeoscienceCollaboration #timescales
