摘要
本文详细地论述了秦岭铅硐山－手搬崖－银洞梁泥盆系铅锌矿床含矿地层的沉积特征，首次提出含矿地层为低能潮坪－湖相的碳酸盐沉积，并详细划分为潮下湖、低能潮间、生物礁、滩等沉积相，为本区今后矿床成因的深入研究提供了新的基础地质资料。
This paper describes in detail the sedimentary characteristics of the Devonian orebearing strata of the Pb-Zn deposits in the Qiandongshan-Shoubanya-Yingdon zonein the Qinling Mountain area. The author interpretes for the first time these strata as thecarbonate deposits in low-energy tidal flat-lagoon factes,which may be classified into thesubtidal lagoon,low-energy intertidal,organic reef and bank factes,thus providing new geological information for further study of the genesis of the ore deposits in this region.
