Silicon and oxygen isotope evidence for exhalative genesis of the Devonian Pb-Zn deposits in the Feng-Tai region, Qinling Mountains, China

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