| 摘 要： | 太阳坪金矿位于鱼洞子-碧口地体和扬子地台、阳平关和青川断裂之间。矿区共圈定了5个金矿体,矿体产于志留系黄坪组地层中,受韧脆性剪切带断裂带控制明显,矿体形态主要为脉状、透镜状,矿石类型主要为石英脉型,围岩蚀变较强烈,主要为硅化、黄铁矿化。地球化学特征表明成矿物质主要来自于深部壳源,韧脆性剪切带是本区的导矿构造,也为成矿提供就位空间。

| Abstract: | Taiyangping gold deposit is located between the Yangzi platform and Yudongzi-Bikou massif or the Yangpingguan and Qingchuan boundary faults. There are outlined 5 gold ore bodies,ore bodies are formed in the Huangping formation of Silurian system,which are obvious dominated by ductile-brittle shear fault zone,the morphologies of ore body are mainly Veined,lenticular,Ore types are mostly quartz veins,wall rock alteration includes silication,pyritization. The geochemical characteristics indicate that the ore-forming materials come from the deep position of crust,ductile-brittle shear zone not only are the passage of ore fluid,also provide ore-contained space for mineralization.. |
