Thermal model for impact breccia lithification: Manicouagan and the moon

Abstract

This paper extends the thermal model of Simonds to the full spectrum of impact-produced rocks ranging from fragmental breccias to impact melts. This is done by relating the basic textural features of impact-lithified rocks to variations in the mixture, of superheated impact-fused material originating near the point of impact and much cooler fragmented debris originating farther from the point of impact.
