Wulong gold deposit is a large scale gold lodes.The gold mineralization is close relatedto the Yanshanian period tecto—magmatisms.Geological,Petrochemical,geochemical andisotopic characteristics have been studied and indicate that Sanguliu intrusion、dikes and goldmineralization were the products of remelting of old gold—bearing source beds.They comefrom the same deep—seated magama chamber.Wulong gold deposit belongs to remelted mag-matic hydrothermal gold deposit.

五龙金矿是一大型脉状金矿床,金矿化与燕山期构造—岩浆活动密切相关,野外地质特征及大量岩石化学、地球化学及同位素资料表明,三股流岩体、脉岩和含金石英脉是古老含金矿源层重熔的产物,三者具有相同的来源。矿床成因类型为重熔岩浆热液金矿床。

Xianjin chang gold deposit occuring in Archaeozoic charnohite and tonalite is near Zhuang xianghu quartz-diorite stock, which is Mesozoic in age. In the mine field, the dikies included basic, medium and acid rooks were widely distributed. Both the stock and the dikies have high gold abundancec, which are much higher than the clarke value. The gold deposit is consist of several auriferous quartz-veins, which are related geneticly to the dikies in spatial position and age. The compositions of sulphur isotope of the gold deposit are δ34S = 2. 08‰-10. 5‰, which descend gradually due to the increase of the distance from auriferous quartz?veins to the zhuangxianghu stock. Ore lead isotopic compositions of various auriferous quartz ?veins are stable, which indicate the ore-forming metal of various ore veins come from the same source. On the δD-δ18O diagram, the ore-forming fluid of Xian jinchang gold deposit are plotted near the magmatic water field, indicating that most part of the ore-forming fluid belonged to magmatic hydrothermal fluid and little part came from underground hydrother-mal fluid. According to above date, the Xian jinchang gold deposit is thought as magmatic hydrothermal gold deposit, which related to Zhuangxanghu stock in genesis.

线金厂金矿床赋存于太古宙紫苏花岗岩、英云闪长岩中,矿床与中生代转湘湖石英闪长岩空间关系密切。矿区各类脉岩发育。脉岩和转湘湖岩体的金丰度均远高于克拉克值,二者为同源岩浆不同演化阶段的产物。金矿床由数条含金石英脉组成,矿脉与脉岩有密切的空间关系和时间联系。矿床硫同位素组成呈有规律变化,即随矿脉与转湘湖岩体之间距离增加,δ~(34)S逐渐降低。矿床各矿脉铅同位素组成变化小,表明成矿物质为单一来源。在δD—δ~(18)O图解上,成矿流体投影点落于岩浆热液区附近,表明成矿流体主要为岩浆热液。根据以上特征,可以认为线金厂金矿床是与转湘湖岩体有成因联系的岩浆热液型金矿床。

On the basis of gold analyses of 1080 samples in Jinchangyu district, gold abundance ofdiffernt rocks was counted. The result shows that the gold abundance is similar to that ofcrust.S,Pb,C,O isotopes of ores are consistant with those of vein rocks and granite,but dif-ferent from countryrock-amphibolite. Factor analysis of REE shows that ore ,vein rocks andgranite are correlated. Compared with other magmatic hydrothermal gold deposits, Jin-changyu gold deposit has magmatic element association....

On the basis of gold analyses of 1080 samples in Jinchangyu district, gold abundance ofdiffernt rocks was counted. The result shows that the gold abundance is similar to that ofcrust.S,Pb,C,O isotopes of ores are consistant with those of vein rocks and granite,but dif-ferent from countryrock-amphibolite. Factor analysis of REE shows that ore ,vein rocks andgranite are correlated. Compared with other magmatic hydrothermal gold deposits, Jin-changyu gold deposit has magmatic element association. According to the proves above,it canbe concluded that gold of the deposit is derived from the magma which has the same origin asthe granite.

本文在测试金厂峪金矿区1080个样品的基础上,统计出各类岩石的金丰度,其与地壳中的金丰度值相当。金矿床矿石的硫、铅、碳、氧同位素值与脉岩和花岗岩相近,而与围岩斜长角闪岩有别,因子分析结果也表明矿与脉岩、花岗岩位于同一组,显示三者具有地球化学的亲缘性。与其他岩浆热液金矿床相比,金厂峪金矿床具岩浆热液金矿床成矿元素组合特征。据此确定金厂峪金矿的成矿物质来自于与花岗岩同源的岩浆。
