摘要

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。

Abstract: Ailaoshan gold metallogenic belt is one of the most important gold metallogenic belts of Himalaya epoch in China, and Daping gold deposit is the most representative gold deposit in this metallogenic belt. On basis of the introduction of the geological features of Daping gold deposit, taking the relevant theories and methods of ore-controlling structure analysis, mineral exploration and metallogenic prediction as the main means, comprehensive investigation and research work are carried out around the geological structure pattern of the Daping gold deposit, the type and nature of ore-controlling structure of the main gold belt, the geometrical shape and extension of the main ore bodies, and the spatial distribution characteristics of the gold bodies. It is believed that the main conductance structure of the deposit is Xiao xinjie fault, and the secondary fault system, formed under the influence of the left walking slide on Xiao xinjie fault, is the main reservoir structure. On this basis, the tectonic ore-controlling model and prospecting model are established, and the direction and space of the deep and peripheral ore-prospecting of the main ore belts are stated, which can provide scientific basis for the deep prospecting verification.
