英文摘要：

Exsolution microstructures in minerals of rocks from orogenic belts played an important role in recognition of ultrahigh-pressure （UHP） metamorphism in their host rocks by defining the subduction depth and improving our understanding of the dynamics during the subduction and exhumation of UHP rocks. However, it is a challenging scientific topic to distinguish the ＇exsolution microstructures＇ from the ＇non-exsolution microstructures＇ and decipher their geological implications. This paper describes the subtle differences between the ＇exsolution microstructures＇ and the ＇non-exsolution microstructures＇ and summarizes the progress in studies of exolution microstructures from UHP rocks and mantle rocks of ultra-deep origin. We emphasize distinguishing the ＇exsolution microstructures＇ from the ＇non-exsolution microstructures＇ based on their geometric topotaxy and chemistry. In order to decipher correctly the exsolution microstructures, it is crucial to understand the changes of chemistry and habits of host minerals with pressure and temperature, Therefore, it is important to combine observations of exsolution microstructure in natural rocks with experimental results at high pressure and temperature and results of micro-scale analyses. Such studies will improve our understanding of the UHP metamorphism and cast new lights on solid geoscience issues such as deep subduction of continental crusts and crust-mantle interactions.
