The genesis of depositwhicn has been discussed are from gold source form of gold mobilization,and condition of gold abudence and concentration. The hydrothermal alteration occurred in ultrabasic rocks is of great importance for the formation of gold deposit

金厂金矿床是我国西南最大的与超基性岩有生因关系的中低温热液石英脉型金矿床。本文论述了矿床地质特征、金质来源、金的活化迁移以及金的沉淀富集成矿机理。笔者认为成矿物质主要来源于超基性岩体,并与其强烈的蛇纹岩化、碳酸盐化等蚀变作用密切相关。金厂超基性岩体不尽为金的活化迁移提供了热力条件,而且是成矿母岩。尽管部分金质来自矿源层,但只是金的次要来源。本文从与超基性岩有关的中低温热液叠生成矿作用,探讨了金矿床的成因问题。

Wulong gold deposits are distributed in the Precambrian granites gneiss and closely associated with the Jurassic granite. The research work has been done on the ore mineral association and the distribution of minor elements in individual minerarls. Co/Ni value in sulfide ranges from 0.41 to18.57, with mean value of 5.05.The homogenization temperature of the gas-liquid inclusions in the quartz of the vein ranges from 190℃ to 330℃. The compositions of the liquid and trace gases of the inclusions show the characteristics of Cl~(-1)-F~(-1)-SO_4~(-2), Na~(+1)-K~(+1)-Ca~(+2). The ore-forming solution is weak acid.Sulfur isotopic composition of ores is similar to magmatic hydrothermal deposits. The δ~(34)S value ranges from 0.9‰ to 3.5‰. Lead isotopic composition in the deposits is relative stable. All of them belong to the ordinary lead type. Most of the calculated model ages range from 719 to 847 Ma. The ~(238)U/~(204)Pb and Th/U ratios for the provenace of the lead comes from the upper crust, while a little comes from the lower crust or the upper mantle.In terms of the transecting relationship of quartz vein and dike, the age of formation of the gold deposits is between 117-52 Ma.According to the above data, the authers suggest that the gold deposits belong to the magmatic hydrothermal deposits of gold-bearing quartz vein that closely associated with the Jurassic granites.

This paper deals with some geochemical features of the Saiwusu gold deposit of the quartz vein type, the difference of gold quartz veins and barren ones, and geochemical features of the gold quartz veins at the occurrence position of the ores. Focal point of the discussion is put on the vertical variation regularity of the geochemical features of the gold quartz veins and the zoning of anomaly. In addition the gold ore yield prognostic indicator of the quartz veins is also summarized.
