摘要
通过对井下现场调查、构造编图和成矿期构造应力场的数值模拟等方面的成果综合分析,提出金华山金矿区控矿构造型式为前孙家—洼孙家主断裂及其平行次级断裂所夹的雁行张裂带。矿区构造控矿规律表现为:构造与矿化具有垂向上的分层性,构造张开中心与矿化富集中心具有一致性、成矿构造方位具有近南北向和北北东向的优选性、矿体总体产状的南东倾和南西侧伏的规律以及脉岩具有明显的控矿作用等。在此基础上对本区下一步的找矿提出了明确的方向。
According to geological investigation in tunnel, map compilation of structure and numerical simulation of tectonic stress field in mineralization period, the type of ore-controlling structure in this area is proposed, which is the echelon tensile fracture belt controlled by Qiansunjia-Wasunjia main faults and its parallel secondary faults. Structural ore-controlling regularity is shown as: the zoning of structure and mineralization in vertical direction, the coinci-dence of structural opening centre and centre of mineralization enrichment, the preferred direction of near SN and NNE metallogenie structure, the regularity of southeastern tendency and southwestern lateral trending of orebody, andthe obvious ore-controlling role of vein rock. On this basis, the next prospecting directions and locations were proposed.
