The present paper deals with geological-geochemical characteristics of the ore-hosting strata of molybdenum and tungsten deposits in the nonferrous metallogenic belt of eastern Qinling. On the basis of a wealth of quantitative data obtained from the systematic sampling along seven measured geological-geochemical sections of ore-hosting strata, lithological characters, variation in contents of molybdenum and tungsten, distribution of trace elements, and multivariate regression analysis for correlation between molybdenum and trace metallogenic elements (copper, manganese, lead, zinc, tungsten), it is evident that the major ore-hosting strata for molybdenum and tungsten deposits are Baishugou Formation, Sanchuan Formation, Nannihu Formation, Meiyaogou Formation of Luanchuan Groupand Longjiayuan Formation of Quandaokou Group; these strata, therefore, are host rocks for large-size molybdenum and tungsten deposits: the Shangfang molybdenum deposit occurs in Meiyaogou Formation, the Nannihu molybdenum dgposit is Present in Nannihu Formation, the Sandaozhuang molybdenum and tungsten deposits exist in Sanchuan Formation and Baishugou Formation, and the Yechangping molybdenum depgsit is seen in Longjiayuan Formation and Xunjiansi Formation. The richer molybdenum and tungsten in ore-hosting strata might be attributed to inheriting these elements from erosional source rocks of Taihua Group and Xionger Group. This is a regional geochemical characteristic of the eastern Qinling metallogenic belt. Although different stratigraphic formations, members or lithologic units have remarkably different average contents of molybdenum and tungsten, they are all characterized strikingly by very high contents of these elements, i. e., from several to tens of times higher than their abundances in the earth's crust (molybdenum 1.3 ppm, tungsten 1.1 ppm). The preliminary concentration of the metallogenic elements in these strata, which served both as Wall rocks and as ore source beds, lald the material foundation for the formation nf Iarge-size molybdenum and tungsten deposits in eastern Qinling.

对东秦岭有色金属成矿带中典型矿床赋矿地层的地质地球化学剖面、岩性特征、沉积环境、钼(钨)元素含量、微量元素分布及钼与微量成矿元素相关关系的多元回归分析等研究结果表明,栾川群白术沟、三川、南泥湖、煤窑沟及官道口群龙家园等各组地层是该成矿带中主要控矿层位;滨海相及滞流较深相条件下沉积的陆源碎屑岩类平均含钼(钨)较高,赋矿地层富含钼(钨)可能与继承蚀源区太华群和熊耳群钼、钨高含量有关;钼与钨、锰成显著的正相关,而与铅或锌成负相关;东秦岭赋矿地层的直接标志是钼、钨平均含量均几倍到几十倍地高于它们在地壳中的丰度,该赋矿地层就是矿源层。并分析了主赋矿地层与非主赋矿地层中钼、钨的丰度,证实了矿化与含矿地层之间的内在联系。确认该成矿带中大型铝(钨)层控矿床之赋矿地层既是它们的矿源层,又是它们的围岩,这些含矿地层是形成东秦岭成矿带中大型、特大型钼、钨矿床的物质基础。

In this paper the characteristics of development of structure in the Lengshuikeng Ag—Pb—Zn ore field and some problems of tectono—geochemistry are mainly discussed. By means of joints' statistical analysis,microstructure analysis and fabric analysis,the mechanical natures and manner of action of NE—,NW—and EW—trending fanlts in the ore field are also discussed. According to the analysis of three sections of tectono—geochemistry in the Yinluling ore deposit, the relation between the distribution and abundance variation of main ore-forming elements and associated elements and development of structure shows that the tectono—geochemical field possesses definite regularities. The fault F_1 is regional and important rock—and ore—forming and rock—and ore—controlling structure in the ore field. In this work the fault F_1 zone at the Chatian section is preliminarily discussed on the features of tectono—geochemistry.
