Title: TYPES AND PROSPECTING TREND OF LEAD AND ZINC ORES IN SHAANXI PROVINCE
Abstract: The genetic types of lead-zinc deposits in Shaanxi province are divided into four grades on the basis of analysis of literature information about the previous and new-discovered lead-zinc resources,in which the first grade includes endogenetic deposit,exogenetic deposit,metamorphic deposit and diplogenetic deposit;and the second grade stratabound deposit,regionally metamorphosed deposit,sedimentary deposit,volcanogenic deposit,hydrothermal deposit,contact-metasomatic deposit(skarn-type) and pegmatite deposit,in which the stratabound type is the most important and the regionally metamorphosed types secondary.The metallogenic series pertaining to the major lead-zinc deposits is primarily designated as 4 groups of metallogenic series,6 types of metallogenic series,9 metallogenic series,in which the metallogenic series,mostly intimate to lead-zinc deposits,are(1) submarine hydrothermal cascade-sedimentary;(2) related to thermal water leakage;and(3) lead-zinc-copper series of submarine cascade sedimentary-hydrothermal deformation types,5 III-grade mineralized zones relevant to lead-zinc deposit and 7 IV-grade mineralized zones.There are 12 lead-zinc mineralized zones in this area,of which 7 are important.They are Qiandongshan-Huangboyuan lead-zinc-copper mineralized zone,Yindongzi-Tongmugou silver-lead-zinc-barite zone,Dongchuan-Xiaochuan lead-zinc-copper zone,Xitonggou-Banyanzhen lead-zinc-gold-mercury-antimony zone,Zhaowan-Huangshiban lead-zinc-gold zone,Yangpingguan-zhujiaba Paleozoic lead-zinc-cobalt-phosphor-sepiolite zone and gold-silver-lead-zinc-copper-sulfur zone from Chadianzi in Mianxian-Qingmuchuan in Ningqiang.
