Abstract
The Hukeng granite body locates in southeast limb of Wugongshan compound anticline, where developed large scale tungsten deposit that is an important part of poly-metallic metallogenetic belt in South China. The thermal history of the Hukeng granite has been studied based on zircon U-Pb dating, whole rock Rb-Sr dating and K-Ar dating of muscovite from the same rock body. From the beginning of zircon crystallization to the closure of whole rock Rb-Sr system, the Hukeng granite body had a relatively fast cooling rate (65°C/Ma), and from the closure of whole rock Rb-Sr system to the closure of K-Ar system of muscovite, the granite body had a very fast cooling rate (208.3°C/Ma). The Hukeng granite body had a very short cooling period (<5Ma) and experienced a rapid cooling process.
