ORE-CONTROLLING STRUCTURAL CHARACTERISTICS OF DAPING GOLD DEPOSIT IN YUNNAN AND PROSPECTING ORIENTATION RESEARCH

  • 摘要: 哀牢山金成矿带是我国最重要的喜马拉雅期金成矿带之一,大坪金矿是该成矿带内最具代表性的金矿床。本文在介绍该矿床地质特征的基础上,以矿田控矿构造解析、矿产勘查及成矿预测等相关理论与方法为主要手段,对大坪金矿区的地质构造格局、主要金矿带控矿构造类型及性质、主矿体空间几何形态及延伸特征、金矿体空间分布特征等开展综合调查及研究工作。研究认为小新街断裂为矿床的主要导矿构造,在小新街断裂左行走滑作用影响下形成的次级断裂系统为主要的储矿构造。在此基础上建立构造控矿模式,指出主要矿带深部及外围找矿方向及空间,为深部找矿验证提供科学依据。
