Abstract
This paper deals with the effects of thermal and collision events which had been experienced by the Jilin (H5) and Qingzhen (EH3) chondrites before they fell to the earth. The HRTEM and optical microscopic investigations show that the Jilin chondrite has undergone more extensive thermal heating and two stages of collision, while the Qingzhen chondrite has experienced weak thermal events after the accretion of its parent body and one stage of moderate collision. The schematic diagrams of the process of formation and evolution of these two meteorites are given in the present paper.
