中文摘要:
      勐板铅锌矿区位于云南西部的保山地块中,该区复杂的地质构造活动为铅、锌等金属矿床的形成奠定了良好的成矿地质基础,但也极大的增加了矿产资源勘查的难度。为进一步探索勐板矿区的矿产资源储备前景,本研究基于岩(矿)石标本物性分析和现场的试验结果,发现该区含矿的岩体可产生明显的激电异常。故在研究区范围内部署多条激电中梯剖面,圈定出9个异常区,综合化探、地质资料成果,确定了5个重点找矿靶区。基于上述工作,在重点异常区布设两条激电对称四极测深剖面,对重点异常体的深部纵向分布和延伸进行探索。本文以研究矿区横纵向激电响应特征为主,地质、化探成果为辅的综合找矿方法技术组合,可为云南勐板地区及其邻区或类似地区的矿产勘查工作提供一定的借鉴。
英文摘要:
      Mengban lead-zinc mining area is located in Baoshan block in western Yunnan Province. The complex geotectonic activities in this area had laid favourable solid metallogenic foundation for the development of lead and zinc deposits, which also raised the difficulty on exploration of mineral resources. In order to further explore the prospects of mineral resources reserve in Mengban mining area, we found that the ore-bearing rock mass can observably generate induced polarization anomalies, based on the physical property analysis of rock (ore) samples and field test results. Therefore, several dual-frequency IP intermediate gradient profiles were deployed within the study area with 9 abnormal areas delineated, it resulted that five key prospecting targets have been determined by synthesizing the geochemical and geological data. Based on the above work, two IP Schlumberger sounding profiles were deployed in the key anomaly area to explore the deep vertical distribution and extension of the key anomaly body. This study provides a reference for the mineral exploration in Mengban area and its adjacent areas or similar areas, which is based on the study of the horizontal and vertical IP response characteristics in the mining area and supplemented by geological and geochemical exploration results.
