| 摘 要： | 戏子洞铜多金属矿主要产于燕山期花岗闪长斑岩及其接触带附近,赋存于花岗闪长斑岩、矽卡岩内,具有典型岩浆热液矿床成因特点。在详细分析戏子洞铜多金属矿地质特征的基础上,认为矿体主要受花岗闪长斑岩、奥陶系与志留系之间岩性差异界面及北东向层滑断层等因素综合控制。

| Abstract: | The Xizidong copper polymetallic deposit in Ruichang of Jiangxi Province is hosted in Yanshanian granodiorite porphyry and the adjacent contact zone, with host rocks being granodiorite porphyry and skarn, and is a typical magmatic hydrothermal deposit. Detailed analysis of the geological characteristics shows that the orebodies are mainly controlled by granodiorite porphyry, the lithological difference interface between the Ordovician and Silurian strata, and the NE-trending strike slip faults. The orebodies occur in the fracture zone formed due to fault slip of the interface layers, and the ore-bearing rocks include granodiorite and skarn. Integrated analysis shows that this deposit shows a comprehensive control by stratigraphic-lithological, structural and magmatic factors, and each factor plays a different role at different stages of deposit formation. |
