🧪⚒️ What did the massive flux of large impacts do the Early Earth's crust? "the upper 8 km shell...may have been made highly permeable by impacts prior to 4.3 Ga...a significant portion of this volume would have been permeable until 3.5 Ga - likely leading to prolonged hydrothermal activity."
Vast permeable regions were generated in the upper crust by impact-generated fracturing in the Hadean and Archean The volume of impact-induced permeable regions is strongly dependent on impact en...
