Seminar: Deep microbial colonization during impact-generated hydrothermal circulation of impact structures

LIVE SEMINAR: Tuesday 10th February 2026 16:00 CET Deeply fractured rocks within meteorite impact structures have been hypothesized as hot spots for microbial colonization on Earth and other planetary bodies, owing to their characteristic long-term heat flow, impact-generated hydrothermal (IGH) systems with geochemical and thermal gradients, and pore space enabling microbial colonization. Biosignatures of such colonization are rare, however, and most importantly, direct geochronological...
