摘要
Single zircon MC-ICP-MS U-Pb dating and lithogeochemical studies of gabbro-diorite intrusives in the Huogeqi orefileld were conducted for the purpose of constraining their petrogenesis and their relationship with copper mineralization. Based on field observation and decrepitation curves of quartz and chalcopyrite, the authors have reached the conclusion that the Huogeqi copper deposit was reformed by magmatic hydrothermal fluid along the contact zone between the gabbro-diorite and the copper ore body.
