This article is our initial understanding of the process of studying the past data, is the result of collective labor, drafted by the author, and seek the views of comrades finalized. The text of the fallacy and inappropriate, please readers criticism. The Middle Devonian lead-zinc metallogenic belt in the Qinling Mountains is one of the major lead-zinc metallogenic belts in China. It is located in the east of Minxian in the southern part of Gansu and Shaanxi provinces and distributed in east-west belt. In the past a lot of work has been done to obtain a wealth of lead-zinc mineral reserves, known mineral resources have greater potential. Metallogenic belt belongs to South Qinling Variscan - Indosinian caprock fold belt. Middle Devonian this area is an east-west ancient sea. The ore-forming materials enter the sea area and diagenetic materials are deposited at the same time, and the ore bodies are formed by the regional diagenesis, which is then transformed into long-term
