| 中文摘要:应用个旧矿区控矿因素、成矿-控矿模式、元素分带规律, 结合矿区找矿勘查现状指出了今后在个旧矿区深部找矿的三个主要方向: 一是花岗岩凹陷构造中的找矿; 二是在断裂与深部花岗岩凹槽或“脊状”突起构造中的找矿; 三是在花岗岩次级突起上的找矿。提出了在个旧东区五大矿田及南部找矿的主要“靶区”、重要“靶区”和一般“靶区”。 |

| Abstract:Based on the data available concerning the ore-controlling factors, the metallogenic-ore-controlling model, and the element zoning regularity of the Gejiu ore district, in combination with the present situation of ore exploration in the ore district, the authors point out three major directions for further ore-prospecting work at the depth of the Gejiu ore district, i.e., the depression structure of the granite, the depression or ‘carinate’ relief structure of the granite at the depth, and the second-order relief of the granite. The major target areas, important target areas and common target areas for ore-prospecting work in five major ore fields of eastern Gejiu ore district as well as in the southern area are also delineated. |
