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.

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。

Metamorplic gold deposit is applied to that of gold ore anriperous sulphide quartz vin.developed in the cause of evolution of the earth's crust.It is related to the pre—cambran greenrocks. On the basis of the characteristics of the crust changes and the mineralization,the deposits can be classified into 4 type:the bedded gold ore deposit in silicoous ferriginous formation;the matamorphic hydrotherrnal gold vin in the“zone of greenrock”;the mixfed hydrotherrnal gold vin in migmatite;the hydrothermal gold...

On combination with the history of the crust evolution,the auther supposed a model of“rectilinear development”of the crust and mineralization.

Mineral associations of gold deposits of following types are of typomorphic significance. There are: precious metal bearing shale hosted type, Au-U bearing meta-conglomerate(conglomerite) type, volcanogene epithermal type, Hemlo type and gossany type. 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.

本文提出了贵金属页岩型金矿床、金铀变质砾岩型金矿床、浅成火山热液型金矿床、赫姆洛型金矿床和铁帽型金矿床矿物共生组合具有标型意义。同时指出只有镍黄铁矿、水硅铀矿和火山热液型金矿床蚀变带中的绿帘石为标型矿物。并以新资料介绍了金矿石矿物具有形态、化学成分、晶体结构、物理性质、包裹体成分及同位素组成方面的找矿标型特征。最后列举了近几年成功地应用金矿找矿矿物学,对中国一些金矿区的找矿工作成果。
