The formation and emplacement of some hydrothermal metal deposits, such as Jiaodong gold deposits, are obviously controlled by the nature and evolution of the fault structure. Group members, Kuifeng Yang and Xuan Liu, are interested in retrieving the dynamic properties of the fault and the variation of corresponding tectonic stress field during ore forming by means of structural geological survey.

And at present, our work is mainly focused on the research of Jiaodong gold deposits. In addition, metal deposits are usually formed in a certain depth (1-10 km) of crust, thus their present-day crustal depths (usually less than 1 km) clearly indicate that they underwent a tectonic or erosion process.

We are currently trying to combine low-temperature thermochronology (U-Th-He, fission track) and structural measurements to study the after-forming thermal history of the deposits, and constrain their exhumation degree and preservation potential.
