Abstract

The results of our micro-mineralogical study show that the shock-induced temperature and pressure distribution in the Yanzhuang chondrite was not uniform, and four shock phases in this meteorite can be divided on the basis of shock effects of its rocks and minerals. They are shock-melt and recrystallized phase (M), very strongly shocked phase (S6), strongly shocked phase (S5), and moderately shocked phase (S4). However, the shock-induced high pressure and high temperature did not result in the change of bulk compositions of different shocked phases in this meteorite. The collision event between two planetoids that caused the formation of Yanzhuang parent body happened at 2.6 Ma ago and the estimated collision speed was 7–8 km/s.
