摘要
在野外地质工作的基础上,采用Landsat7 ETM+和Landsat8 OLI_TIRS融合图像为数据源,对鲁西兰陵龙宝山地区地层、构造和侵入岩遥感地质解译发现:龙宝山地区金成矿与地层无明显关系,北北东向断裂以及龙宝山杂岩体周围的放射状断裂构造系统和岩体与围岩的接触带构造等控制金矿化的形成及分布,中生代燕山期侵入岩特别是龙宝山杂岩体与金成矿直接相关。遥感找矿规律表现为解译线型构造、环型构造的交汇部位及其附近,且羟基异常发育的地段以及杂岩体的边缘,是寻找该类型金矿的最佳地段。
Based on feld work and using the fused images of Landsat 7 ETM ＋ and Landsat 8 OLI_TIRS data, remote-sensing interpretation of strata, structure, and intrusive rocks was carried out in the Longbaoshan area. Gold mineralization is not obviously related to strata. Gold mineralization and deposits are controlled by NNE-trending faults, radial faults, and structural systems around the Longbaoshan complex and contact belt between the rock mass and surrounding rock. Mesozoic Yanshanian intrusive rocks, particularly the Longbaoshan complex, are directly related to gold deposits. The rule of remote sensing prospecting was expressed as the best location to search for this type of gold deposit is the intersection of linear and ring structures and its vicinity, where the hydroxyl is abnormally developed at the edge of the complex.
