At the present time Jin Chang gold deposit is the only large one occurring in rocks in Yunnan. As far as we know in China it is also the only example showing that ultrabasic rocks provided gold for forming a large type gold deposit. This paper is to describe the general geological conditions in this area and the geological characteristics of the deposit. The formation of the gold (nickel) deposit is discussed from various aspects such as the nature of mineralizing source rocks (the gold-bearing ultrabasic rocks), the sulfur isotope composition, the source of silica, the gold abundance of ultrabasic rocks and the gold concentration in their weathering crust and the cilicified rocks, the characteristics of fluid inclusions and temperature of mineralization,the conditions of gold mobilization and removal the hydrothermal alteration series occurred in ultrabasic rocks, etc. It is thought to be mainly a middle-temperature hydrothermal gold deposit formed by acidic hydrothermal alteration of ultrabasic rocks. 'The Hydrothermal Type Gold Deposit in Altered ultrabasic Rocks' is a new type of gold deposits and suggests a new concept to metallogeny.

金厂金矿是我省当前唯一的大型金矿床,也是国内已知由超基性岩提供金质、构成大型金矿床的唯一实例。本文介绍了矿区地质概况和矿床地质特征,从矿源岩(含矿的超基性岩)属性、硫同位素组成、硅质来源、超基性岩含金丰度值及其风化壳和硅化岩的金富集、包裹体特征及成矿温度、活化转移条件——超基性岩热液蚀变序列的存在等方面,对金(镍)矿床的形成进行了探讨。认为它是由超基性岩经酸性热液蚀变而形成的中温热液型(为主)金矿床。“超基性岩蚀变热液型金矿床”,在岩金矿床中是新的类型,在矿床成因学上是新的概念。

In addition , only pentlandite, coffinite and the epidote in the alteration zone of volcanogene hydrothermal gold deposit are typomorphic minerals. In this paper the author, with new data he collected, illustrates the typomorphic characteristics of minerals in gold ore, including morphology, chemical composition, crystalline structure, physical Property nclusion data and isotope abundance. Lastly, some successful results recently obtained by the application of prospecting mineralogy Chinese to gold ore exploration are cited.

There are always mechanical mixtures of various minerals, impurity elements and fluid inclusions in quartz, the features of its infrared spectra are quite different. The experiments have shown that as orthoclase and oligoelase are mixed in quartz, the intensities of absorption band at 790 and 909cm~(-1) are related to the content of the quartz, and at 625 and 641cm~(-1) are to the content of the orthoclase and the oligoclase respectively. A negative correlative relation appears between the intensity at 695cm~(-1)...

There are always mechanical mixtures of various minerals, impurity elements and fluid inclusions in quartz, the features of its infrared spectra are quite different. The experiments have shown that as orthoclase and oligoelase are mixed in quartz, the intensities of absorption band at 790 and 909cm~(-1) are related to the content of the quartz, and at 625 and 641cm~(-1) are to the content of the orthoclase and the oligoclase respectively. A negative correlative relation appears between the intensity at 695cm~(-1) and the content of impurity-texture aluminium. The correlative coefficient equal to -0.62. The infrared spectra of quartz thin-section may be used to study fluid inclusio'n in the quartz and determine its genesis. In Tuan Jiegou porphyry gold deposits, the relative-absorbance of water is higher and there is on carbon-dioxide inclusion in the quartz. In Jiapigou metamorphic hydrothermal gold deposits the quartz usually contains more CO_2 inclusions. As relative-absorbance of the carbon dioxide in the quartz is higher, the quartz probably is auriferous one.

本文研究证明,当石英中有正长石和奥长石存在时,在790和909cm~(-1)吸收带的强度与石英有关,而625和641cm~(-1)的强度则分别与正长石和奥长石有关。在956cm~(-1)吸收带的强度与杂质结构铝含量之间有负的相关关系,相关系数是-0.62。石英薄片的红外吸收谱可以用来研究它的液态包裹体并决定其成因,在团结沟斑岩金矿床中,石英的水相对光密度较高,并且没有二氧化碳包裹体。在夹皮沟变质热液金矿床中,石英通常含有较多的二氧化碳包裹体。当石英中二氧化碳的相对吸光度较高时,则可能为含金石英。
