贵州省晴隆县金矿成矿特征及找矿方向

Mineralized Feature and Prospecting Direction of the Gold Deposits,Qinglong County,Guizhou

根据区域地质调查和几个矿床、矿点深入研究 ,初步总结了晴隆县碧痕营背斜金矿成矿特征。金矿主要分布在背斜南东翼南段老万场、紫马一带 ,有红土型、卡林型两种金矿类型 ,以前者为主。老万场、王家湾一带红土型金矿从“大厂层”中风化剥蚀堆积形成 ;紫马、羊昌一带红土型金矿从上二叠系龙潭组含金层风化剥蚀堆积形成。根据其成矿特征 ,提出今后找矿方向。

Based on regional geological survey and thorough studies of several deposits and occurrences,the mineralized feature of Bihengyin anticlinal gold deposit of Qinlong is initially generalized. The gold deposits predominantly distribute at the districts,like as Laowanchang and Zima on the south segment of the southeast wing of the anticline,in which such two types as lateristic and karlin gold deposits occurred,giving prior to the former. Lateritic-type gold deposit at the zones of Laowanchang and Wangjianwan formed within Dachang member by weather and denudation; Lateritic type gold deposit at Zima and Yangchang sites generated from gold-bearing layer of Upper Permian Longtan formation by weather and denudation. The prospecting bearing in further is put forward according to the mineralized feature.
