矿石结构有三种,即结晶的自形、半自形、他形粒状;溶蚀结构和碎裂结构。按硫化物的产出状态矿石的构造类型有:块状、浸染状、脉状、团块状及团斑状、斑杂状。
本矿床常见的近矿围岩蚀变有绢云母化、黄铁矿化、硅化、绿泥石化及碳酸盐化。其中与金矿化关系密切的是黄铁矿化、绢云母化、硅化。
The ore structure has three kinds, namely, the crystallization of euhedral subhedral xenomorphic granular structure, cataclastic structure and dissolution. According to the tectonic type of the sulfide in the output state of ore: massive, disseminated, vein, lumpy and porphyritic and mottled.
Near ore wall rock alteration in this ore deposit of common variable are sericitization, pyritization, silicification, chloritization and carbonatization. Which is closely related to the gold mineralization is the yellow iron mineralization, the silk mica, the silicon. |
