What Happened When the Lithosphere of Venus Broke?

by Laurent G. J. Montési 5 January 202115 March 2022

Although Venus does not have plate tectonics today, previous episodes of intense tectonic activity could have resulted in a distribution of crustal thickness and age resembling the plate we see today.

Traces of Impacts on Warm Planetesimals Early in Solar System

by Laurent G. J. Montési and J. Filiberto 9 October 20208 March 2022

Meteorite NWA 11004 contains evidence of melting preceding an impact dated to 4546±36 Ma. Short lived radioactive decay had already heated the parent body of this meteorite before the impact.
