Professor Xie’s research has centred on the behaviour of minerals and rocks under extreme pressure, with particular emphasis on dynamic high-pressure mineralogy, impact metamorphism, and planetary materials. His early systematic mineralogical studies contributed to the discovery of eight new minerals and to the publication of an early Chinese monograph on borate minerals. He subsequently conducted research on the geological and mineralogical effects of nuclear and artificial chemical explosions, contributing to the development of extreme-pressure mineralogy in China and to the interpretation of pressure conditions associated with explosive events. From the early 1980s, he investigated shock metamorphism in terrestrial impact craters and proposed a seven-stage shock metamorphic model for quartz, subsequently refining models for major rock-forming minerals. His later studies of meteorites and impact-crater minerals contributed to research in lunar geology, meteoritic mineralogy, and planetary impact processes, with twenty-seven new minerals discovered or co-discovered through this work. He has also led research programmes concerning the geological environment, resource management, and disaster prevention of the Dongjiang River basin and the Guangdong coast. Professor Xie has published more than 240 scientific papers and authored or co-authored fifteen monographs and a translated work, and has received two National Natural Science Awards and numerous provincial and ministerial awards. Through sustained research in systematic, dynamic high-pressure, and planetary mineralogy, together with academic and scientific leadership, Professor Xie has contributed to the development of mineralogical research in China and to the study of impact processes on Earth and in the solar system.
