研究方向 Research Interests

My research is motivated by a desire to understand how rocks/minerals were formed by extreme deformation events, e.g., faulting or lightning. I mainly work on the investigation of fault behaviors of a fault during the seismic cycle, to obtain earthquake physics for a seismically active fault, and to expand understanding of fault deformation together with significant applications to other natural faults. By means of the integration of the data of (1) natural observation of active fault zones, (2) microstructural /geochemical investigation of fault rocks, and (3) experiments conducted under expected deformation condition, the field- and laboratory-based complementary data set shall uncover the secrets hidden on seismic faults. Meanwhile, I focus on the lightning-induced textures on rocks, namely fulgurite. The high temperature (>1000˚C) and high pressure (~1.5 GPa) textural context of fulgurite are similar to both shocked minerals by meteorite impacts and pseudotachylyte by seismic faulting. Our results shed light on the meteoritics, planetary geology, and regional tectonics and will be of interest of a broad audience (geologists, geochemists, planetary scientists, petrologists, mineralogists, etc.). The relevant published (under review) works in 3 years (2018-2021) are shown as following:
