Description

Fragment de brèche d'impactite du cratère d'impact de Rochechouart (France).

Brèche de Rochechouart

La ville de Rochechouart donne son nom au cratère de l'impact qui a eu lieu il y a 214 millions d'années. Ce fragment montre des fragments de gneiss, de granite, de quartz, et de leptinite liés entre eux par une matrice clastique, composée de poussières qui se sont solidifiées dans le temps.
