大理笔架山金矿区位于藏滇地槽褶皱系与扬子准地台的交接地带,处于红河断裂和程海断裂之间呈倒三角形分布的地段上,这些部位容易形成一系列裂隙及微裂隙,为成矿物质富集的有利场所。矿区共有5种金矿化类型,采用单一的地质找矿方法难以准确反映本区的各类型矿床特征,特别是隐伏的与斑岩有关的金矿床。本文介绍了在矿区开展的物化探综合找矿工作,取得了较好的找矿效果,初步建立起本区物化探找金矿模式。
Dali Beijingshan gold deposit is located in the transition zone between the Tibetian-Yunnan Trough fold system and the Yangtze Platform, and is located on an inverted triangular distribution between the Honghe fault and the Chenghai fault. These fractures are prone to form a series of fractures and micro-fractures. For enrichment of metallogenic sites. There are five types of gold deposits in the mining area. It is difficult to accurately reflect the characteristics of various types of deposit in this area by using a single geological prospecting method, especially the hidden gold deposits related to porphyry. This paper introduces geophysical and geochemical prospecting work carried out in the mining area, and has achieved good prospecting results, and initially established the pattern of physical and chemical prospecting gold deposits in this area.
