The protolish of host rocks and near deposits wall rocks of the orthophyric tectonic altered rock type gold deposits was the orthophyre.It became more complication as underwent the mylonitization,brecciation,catagenesis and the late different alterations.The early alterations of mineralization were the biotitization and potassium feldsparization,and mainly the pyritized phyllite and pyritized fluoritization argillization in the mineralization period,and but the carbonatization in the postore period.The aspect of the hosted and near ore mylonite is hardly identified because of the overprints of multiphase tectonics and alterations.Only on the ground of some vestiges and relics of the blastomylonite seen under a microscope can be they recovered and discriminated.The protolish of indirect wall rock of the orebody is basaltic andesite,which undergoing the contact metamorphism changed into the hornfels consisting of hornblende and plagioclase in the early period.But the texture and structure of the blasted initial rock can be identified.Then it yet underwent a series of the tectonic processes and alterations.Its alterations were mainly the biotitization,chloritization,and the second the carbonatization,potassium feldsparization and albitization.But,in the tectonic altered rocks consisted above altered minerals,the gold bearing content has common not attained to the pay grade.

正长斑岩构造蚀变岩型金矿容矿岩石和近矿围岩的原岩属正长斑岩,它先后发生糜棱岩化,角砾岩化、碎裂岩化,加上后期多种蚀变作用的叠置,使其变得较为复杂。成矿早期蚀变为黑云母化、钾长石化;成矿期主要是黄铁绢英岩化、黄铁萤石泥英岩化;而成岩后期则主要为碳酸盐化。由于多期构造和蚀变的叠置,容矿和近矿糜棱岩外观很难辨认,只有据显微镜下见到的一些残迹和变余的糜棱岩残体来恢复原岩。矿体间接围岩原岩为玄武安山岩,早期曾受接触变质变为角岩。主要由普通角闪石和斜长石组成。可见变余原岩结构构造,后来又接受一系列构造和蚀变作用,主要是黑云母化、绿泥石化,次为碳酸盐化、钾(钠)长石化。但在其形成的构造蚀变岩中,金含量一般未达工业品级

The country rock alteration at Tongchanggou Gold Deposit is well developed and the deposit is controlled by tectonic pulse. The alteration shows irregular ring shape zonations which are divided into four stages i.e. silicification chloritization, sililcification carbonization, pyritization and silicification pyritization. The Gold mineralization occurs in pyritization stage According to characters of country rock alterations, tectonic altered rock type Gold deposit can be explored under the known orebodies.

The geotectonic position of Kuslap Gold Deposit is in the north part of late Devonian Era's Aoyitag Kulliang rift trough of the juncture location between West Orogenic Zone and Talimu Plate.It belongs to a part of Kuslap Talong mineralized zone of West Kunlun Mountain Region.Through field probe,synthetic determination and mineral analysis,it is considered that the region began to be in tension from middle Devonian Era thus taking shape of fragmental rock carbonate formation which became the original ore ...

The geotectonic position of Kuslap Gold Deposit is in the north part of late Devonian Era's Aoyitag Kulliang rift trough of the juncture location between West Orogenic Zone and Talimu Plate.It belongs to a part of Kuslap Talong mineralized zone of West Kunlun Mountain Region.Through field probe,synthetic determination and mineral analysis,it is considered that the region began to be in tension from middle Devonian Era thus taking shape of fragmental rock carbonate formation which became the original ore source bed of gold;the activity of deep concealed rock mass provides the required thermal source of the movement of mineralized materials in the region;tough shear zone is the main passageway for the upflowing of deep gold bearing thermal fluids in the region.Accordingly,the emphasis must by placed on the prospecting of tough shear zone type and tectonic altered rock type gold deposits.

库斯拉甫金矿 ,在大地构造位置上 ,处于西昆仑造山带与塔里木板块交接部位的晚古生代奥依塔格—库尔良裂陷槽的北段 ,属于西昆仑地区库斯拉甫—他龙成矿带的一部分。笔者通过详实的野外考察和综合室内测试、岩矿鉴定等研究资料分析 ,认为该区中泥盆世开始拉张形成的碎屑岩—碳酸盐岩建造 ,是金的原始矿源层 ,深部隐伏岩体的活动为区内金的成矿作用提供了成矿物质运移所需的热源 ,韧性剪切带是区内沟通深部含金热液上升的主要通道。因此 ,在库斯拉甫地区 ,应注重寻找韧性剪切带型金矿和构造蚀变岩型金矿。
