断裂附近的长石交代岩,是苏联地质人员发现的希有金属矿床的重要工业类型。这种矿床与构造一岩浆活化作用有关,形成于古地盾与固结褶皱区范围内。矿床通常赋存于深断裂内,断裂周围的岩石(各种片麻岩、古老花岗岩、基性岩)巴强烈微斜长石化,局部钠长石化和硅化。由于交代作用。产生了类似花岗岩的含希有金属矿化的长石或石英—长石交代岩,有时还保存着原岩的构造。这种矿床空间上与火成岩无关。由于岩
The feldspar metamorphic rocks near the fault are important industrial types discovered by the Soviet geologists for the Hixing metal deposit. This deposit is related to the tectono-magmatic activation and is formed in the range of ancient and consolidated fold zones. The deposits are usually found in deep faults. The rocks around the fault (various gneiss, ancient granites, basic rocks) have intense micro-plagioclase, local albite and silicification. Due to accountability. Generated similar to the granite containing Greek metal mineralized feldspar or quartz - feldspar metamorphic rocks, and sometimes preserved the original rock structure. This deposit is spatially independent of igneous rock. Due to the rock
