Wall rock alteration variable deposit of altered rocks, development, space was zonal distribution alteration Center for silicification porphyry, out, followed by quasi elliptic ring of potash feldspathization belt, biotite zone, sericite of belt and propylitization with (Figure 3.7.4).

１）硅化斑岩带（石英核） 分布于矿床中心，由部分斑岩和其邻近的岩石碎裂后被含钾长石、钠长石网脉石英脉充填交代而成。硅化强的部位已被交代成块状石英岩，弱的仅有稀疏网脉石英脉穿插。

1) the porphyry belt (quartz core) is distributed in the center of the deposit, which is composed of a part of the porphyry and its adjacent rock, which is composed of a quartz vein filling with a quartz vein and quartz vein. The site has been strong silicified metasomatism into massive quartzite, quartz vein only sparse network with weak gangue.
