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...

New research shows a meteorite struck Scotland 1 billion years ago, close in time to some of Earth's earliest land fossils.
A rare glimpse into how ancient ecosystems responded to cosmic disruption.

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

Lead isotopes for #geology. Very handy for understanding igneous rocks - brace of recent open access contributions:

Shoutout to Priyanjan Datta for the 1st paper of his #PhD in #Lithos linking granite Pb-isotope signatures to intracrustal fractionation, crustal thickness, and the evolution of the Delamerian & Lachlan Fold Belt.

Geochronologists love U-Pb dating, but what do you do with all that discordant data? A new tool might help you turn that noise into useful signal. Worth a look. agupubs.onlinelibrary.wiley.com/doi/full/10....

Do you want to go back in time and research ancient geology and understand mineral systems and tectonics? Do you like field and lab work? Come do a PhD with us at Curtin University: www.earthworks-jobs.com/geoscience/c...

Great chat with Bob McDonald on CBC. It's great to be able to share the deep time history preserved in Western Australia. www-cbc-ca.cdn.ampproject.org/c/s/www.cbc....

Great interview on early earth Prof. Johnson and Roland Pease on science in action BBC. www.bbc.co.uk/sounds/play/...

Rocks from 700 million years ago hold the clues. From glaciers bulldozing landscapes to meltwater rivers flushing chemical elements into the oceans = it’s a story of how land, sea, and sky are all geochemically connected. theconversation.com/giant-glacie...

Boom! Earth's (currently) oldest crater right in the centre of the Pilbara Craton. 3.5 Billion Years old. Hummm.... implications for life. www.nature.com/articles/s41...
