Description

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

Brèche à forte fusion : type Babaudus

Baubadus est un lieu-dit situé au centre de l'impact. L'échantillon montre une matrice présentant un taux de fusion extrème. La roche a complètement fondu, et seul les cristaux de quartz ont subsisté. Les bulles nombreuses dont la taille varie du millimètre au centimètre ont été générées par une température de plusieurs milliers de degrés.
