| Abstract: |
| In recent years, the molybdenum ore prospecting achievements in the area of malanyu compound anticline in East Hebei are remarkable, and this area has become an important molybdenum ore concentration area in Hebei province. Many evidences show that molybdenum mineralization is closely related to yanshanian granite intrusions, In this paper, the Husshi molybdenum mine geological characteristics and metallogenic stages are summarized and classified. Complex joints and fissures caused by multistage magmatic intrusion and tectonic activity are the main ore-controlling factors of Huashi molybdenum deposit. Molybdenum mineralization is mainly in the form of molybdenite-quartz vein or molybdenite in the form of thin film and veinlets along the fracture. Comprehensive analysis suggested that the genetic type of Huashi Mo deposit is hydrothermal quartz vein type. |
