How old is the North Pole Dome impact in WA? In doi.org/10.1130/G548..., we date lightning-bolt-like skeletal zircon in shocked rocks and hydrothermal apatite, giving an age of ~3.02 billion years. North Pole Dome is a candidate for Earth’s oldest known impact structure. #geology

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...

Giant glaciers pulverised Earth’s ancient rocks, setting the stage for complex life

Hundreds of millions of years ago, rocks crushed under kilometres of ice injected vital nutrients into Earth’s oceans.

Alert!!! outstanding news!! We discovered the oldest and only Archean impact crater, located in the Pilbara Craton, with expectionally preserved shatter cones and much more! Much more to unravel about their role on the Early Earth ☄️☄️ www.nature.com/articles/s41... @naturecomms.bsky.social

Have you ever wondered what happens to the chemistry and isotopes of deformed garnet? Well, I did and it turned out to be very revealing. Check out our lastest #openaccess paper in EPSL. shorturl.at/S72aN
