文章论述了瑞昌旋卷构造的主要旋迴面之一的宋家湾—武山复向斜与北西向构造带的复合控制武山矿田的形成和分布。通过构造形迹观察、裂隙统计、显微构造和组构分析以及趋势面分析等研究,确定了矿田主要构造格架和成矿构造体系。成矿期的构造应力场主要反映了北北西—南南东方向的挤压和北(北)东—南(南)西方向的挤压作用,两者所形成的构造叠加是形成武山矿田的最重要的构造条件。对于主要控矿断裂带岩石矿物的形变相变特征进行了重点研究,与此同时还探讨了不同方式的构造应力作用对成矿期地球化学场产生的影响,以及某些元素浓度分布和地球化学异常所反映的构造应力场特征。
The paper discusses the formation and distribution of the Wushan orefield in the Songjiawan-Wushan syncoconversion and the NW-trending tectonic belt, one of the major gyration faces of the Ruichang spiral volcanic structure. Through the study of tectonic trace observation, fracture statistics, microstructure and structure analysis and trend surface analysis, the main tectonic framework and metallogenic tectonic system in the ore field are determined. The tectonic stress field in the ore-forming stage mainly reflects the compression in north-northwest-south-south east direction and the extrusion in the north (north) east-south (south) west direction. The tectonic superimposition formed by the two forms the formation of Wushan orefield The most important tectonic conditions. The deformation and transformation features of rock minerals in major ore-controlling fault zones are mainly studied. At the same time, the influences of different tectonic stress on the geochemical field during mineralization and the distribution of some elemental concentrations and geochemistry Tectonic stress field characteristics reflected by anomalies.
