The gold deposits of tectonic altered rock type in the ophiolite of Noith Ailao Mountain are located in the basalts and pyroclastic rocks of the upper ophiolite. The gold deposits are all under the control of northwest faulted structure, and associated with the different veins of lamprophyres and granodioritic porphyrys which have to do with ore-forming process. First wall-rock alteration is carbonation, second are sericitization and pyritisation. Main metallic sulphide ores are pyrites, arsenopyrites,...

The gold deposits of tectonic altered rock type in the ophiolite of Noith Ailao Mountain are located in the basalts and pyroclastic rocks of the upper ophiolite. The gold deposits are all under the control of northwest faulted structure, and associated with the different veins of lamprophyres and granodioritic porphyrys which have to do with ore-forming process. First wall-rock alteration is carbonation, second are sericitization and pyritisation. Main metallic sulphide ores are pyrites, arsenopyrites, stibnites, and form the different assemblages of min-eralization. The forming temperature of the gold deposits is low- to -moderate. The compo-sition of the fluid inclusions is abundant in Na+, Zn2+, Cl-; SO42- , H2O, CO2and so on. The main enrichmicroelements of the gold deposits are As, Sb, W, and REE evolutionary charac-teristics are LREE depressing and HREE increasing. Sulfur and oxygen isotope composition displays that the gold deposits are low -to -moderate hydrothermal deposits and their ore -forming solution is mainly composed of the magmatic hydrothermal solution which is added in some underground water.

哀牢山北段蛇绿岩中构造蚀变岩型金矿床主要产于蛇绿岩上部的玄武岩和火山碎屑岩中,并受北西向断裂构造控制。区内分布有喜玛拉雅期煌斑岩和花岗闪长斑岩等脉岩,其与成矿作用密切相关。围岩蚀变以碳酸盐化为主,其次是绢云母化和黄铁矿化。矿石主要金属矿物为黄铁矿、毒砂、辉锑矿;包裹体成分以Na~+、Zn~(2+)、Cl~-、SO_4~(2-)、H_2O和CO_2为主;主要微量元素是As、Sb、W;稀土元素表现出轻稀土降低和重稀土相对增加的演化特征。硫、氧同位素研究表明,该矿床属于以岩浆热液为主,伴有部分地下水加入的中低温热液矿床。

Dense Au deposit zone is located in the suture between Archaeozoic Zhongchao ancient land plate and Proterozoic Mongoliasea plate , controlled by NW Fuerhe and Gudonghe lithosphericfractures. Au ores are generally enriched in the edges of abovementioned plates, intermediate-acid intrusive complex related to ore-forming resulted from anatectic granite magma. Hoststructures are usually ductile shearzones or schistosity zones in brittle fracture zones. Au ores dominantly belong to sulphide-lacked type, and then...

Dense Au deposit zone is located in the suture between Archaeozoic Zhongchao ancient land plate and Proterozoic Mongoliasea plate , controlled by NW Fuerhe and Gudonghe lithosphericfractures. Au ores are generally enriched in the edges of abovementioned plates, intermediate-acid intrusive complex related to ore-forming resulted from anatectic granite magma. Hoststructures are usually ductile shearzones or schistosity zones in brittle fracture zones. Au ores dominantly belong to sulphide-lacked type, and then to tectonic altered rock type. The dense Au ore zone possesses excellent metallogenic conditions, is the mainprospect area of Au deposits in Jilin Province.

金矿密集带位于太古宙中朝古陆板块与元古宙蒙古海板块之间的缝合线上,受北西向的富尔河-古洞河岩石圈断裂带控制。金矿床普遍产在上述相邻二板块构造的边缘,与成矿有关的中酸性侵入杂岩体多为深熔花岗岩浆的产物,容矿构造往往为韧性剪切带或脆性构造破碎带内的片理化带。金矿床主要为少硫化物型,次为构造蚀变岩型,该带有优异的成矿条件,是吉林省金矿的主要远景区。

Types and stages of wallrock alteration,petrochemistry,minor element and REE geochemistry of tectonic-altered rock in Gala shear zone type gold deposit in the northern sectino of the Garze- Litang fracture zone are discussed.Relation of the gold mineralization with structure and alteration is exPOunded.The gold mineralization is associated with wallrock alteration spatially and temporally.Wallrock alteration resulting form shear deformation is of importance to gold mineralization .

本文重点论述了甘孜-理塘断裂带北段嘎拉金矿床含金剪切带围岩蚀变类型、阶段,讨论了构造-蚀变岩的岩石化学及稀土、微量元素地球化学特征,进一步阐明了构造-蚀变作用与金矿化的关系,即金矿化在空间上与围岩蚀变类型及强度关系密切,在时间上大致同期形成。这种由剪切构造变形作用引起的蚀变作用,对金矿化具有重要意义。
