摘要
该区在大地构造上位于Ⅱ级构造单元江南台隆中雪峰弧形构造带由NE向构造转为NEE向构造而形成的弧形转折部位。金矿床赋存于元古界板溪群(Ptbn)和元古界冷家溪群(Ptln)地层中,严格受元古界浅海相沉积的一套浅变质(碎屑)岩及断裂构造、热液蚀变控制。通过成矿条件综合分析,该区金成矿地质条件优越,具有较好的找矿潜力。
The area is located on the tectonic curved transition parts Ⅱ -class tectonic units the Jiangnan stacked platform uplift in Xuefeng arcuate tectonic belt into a NEE by NE trending tectonic formation of the constructor. The gold deposit occurrence in the Proterozoic Banxi Group (Ptbn) and Proterozoic Lengjiaxi (Ptln), strictly controlled by Fracture structure,hydrothermal alteration and the set of low-grade metamorphic (clastic) rocks in shallow marine deposition of the Proterozoic. Through comprehensive analysis of metallogenic conditions, that the area of gold metallogenic geological condition is superior, and has better prospecting potential.
