云南宾川斜角冲铜金矿地质特征及找矿靶区优选

Geological characteristics of xiejiaochong copper gold deposit in Binchuan,Yunnan and optimization of prospecting targets

本文从分析研究云南省宾川县斜角冲斑岩型铜金矿地质特征入手,提出了石英正长斑岩体边缘“岩浆侵入推挤破裂带”的存在是寻找斑岩型铁金铜铅锌等矿床的重要找矿标志。依据矿区地质背景和构造位置、地质特征、化探原生晕异常特征、民采点矿化信息对矿区进行了靶区优选,优选出了五个找矿靶区。

Based on the analysis and study of the geological characteristics of the oblique angle thrusting porphyry type copper gold deposit in Binchuan County, Yunnan Province, this paper puts forward that the existence of "magma intrusion and extrusion fracture zone" on the edge of quartz syenite porphyry is an important prospecting indicator for porphyry type iron, gold, copper, lead and zinc deposits. According to the geological background, structural location, geological characteristics, geochemical primary halo anomaly characteristics and mineralization information of civilian mining points, the target areas of the mining area were optimized, and five prospecting targets were selected.
