摘要：
<正> The Devonian System in Qinling Mountains consists of thick flyschoid formation formed in E-W Paleozoic rifting basin between the Yangtze Plate and North China Platform. The Feng-Tai ore field is a part of the Qinling Devonian stratiform Pb-Zn metallogenic belt. The ore bodies are all stratiform or stratoid and occur in the transitional zone between the Middle Devonian Gudaoling limestone and the Upper Devonian Xinghongpu fine-groined clastic rocks. The host of the ore deposit is siliceous rocks containing ankerite and siderite. The siliceous rocks are stratiform and mainly composed of micritic quartz. The larger the siliceous
