Abstract: Leitang molybdenum ore spot is a new discovery in the gold-copper polymetallic ore re⁃ source investigation and evaluation area of Baocun（Jingxian County）—Banqiao（Jingde County）area.1∶50， 000 drilling holes revealed that molybdenum mineralization developed in the deep part of the rock mass， and the minerals were mainly molybdenite，pyrite，etc.，which mainly occurred in quartz veins of granodio⁃ rite or the edge of quartz veins，and it was quartz veins disseminated molybdenum ore. Compared with oth⁃ er similar deposits in the area，it is found that Leitang molybdenum ore spot is located in the northern edge of Maolin granodiorite body. The intrusion of Maolin rock mass and its post-magmatic hydrothermal activi⁃ ties provided the necessary heat source for the mineralization，enrichment and mineralization in this area， and were closely related to the structure and hydrothermal alteration. Based on the study，it is considered that Leitang molybdenum deposit is a low temperature hydrothermal deposit，and the deposit type is por⁃ phyry molybdenum deposit.
