南岭地区铜山岭区域构造组合分析及其与矿产关系

    Tectonics portfolio analysis and their rela tion to ore resources in the Tongshanling area,Nanling

    • 摘要: 南岭地区铜山岭区域构造发育,矿产丰富。为了解区内构造与矿产关系,掌握区内控矿主导构造,为区内找矿工作提供指导,本文以1∶5万矿产远景调查成果为基础,从区域地质背景、研究区地质特征、研究区构造组合分析、构造与矿产的关系等方面进行分析,重点研究了区内构造演化与构造变形机制, 阐明了构造形迹之间、构造与矿产关系,指出东西向的铜山岭-九嶷山基底断裂在成矿作用中起主导作用,控制了研究区岩浆岩和矿产的空间展布,次一级的南北向、北北东向、北东向褶断带是矿体赋存有利空间。

       

      Abstract: Tectonic is developmental and mineral is rich in the Tongshanling area, Nanling. In order to understand the relationship between tectonic and mineral resources in this district, and to master the main ore-controlling tectonics, and to provide guidance for the next exploration work,based on the results of 1:50000 mineral prospects survey, the regional geological background, the geological characteristics,the tectonics portfolio characteristics of the study area, and the relationship between tectonics and mineral resources were analyzed in this paper. The tectonic evolution and tectonic deformation mechanism was discussed in this district among tectonics, and between tectonics and mineral relations. The EW-tending Tongshanling -Jiuyishan basal faults was pointed out assumed the leading role in mineralizationin. Magmatic rocks and minerals were controlled in the spatial distribution. The second level SN-tending, NNE-tending, NE-tending fold and fracture belt is favorable space for ore-forming.
