摘要
辽东玉隆铅锌矿田处于辽吉古裂谷西端中央地带,是区域上重要的铅锌成矿带。区内含矿母岩-大石桥组三段条带状透闪白云石大理岩发育,铅锌矿床成因类型为沉积-变质热液再造矿床,控矿构造为F1次级褶皱、F2褶皱转折端和褶皱翼部剪切滑动角砾岩带。文章提出区内存在类似检德铅锌矿床"如云硐"二期向斜的大褶皱转折端,论述了玉隆至烟囱砬子至响水沟二期向斜一线距地表600~1500m空间存在铅锌矿工业矿体的地质依据。
The Yulong lead and zinc ore deposit of eastern Liaoning, as an important lead zinc belt in the region,is located in the central zone of the western end of the Liaoning-Jilin Paleoproterozoic rift. There is mineral parent rock and stripe-like tremolite dolomite marbles in the third section of the Dashiqiao formation group in this area. The genetic type of the lead and zinc deposit is sedimentation-based and reworked by metamorphic hydrothermal solution. The ore-controlling structures include the second-order fold F1 , turning end of fold F2 , and limb of the fold with sheafing slide breccia belts. This paper suggests that there is a second-stage synclinal turn end of large fold, similar to the Ruyun cave of the Jiande lead and zinc deposit existing in this area. The geological evidence shows that industrial ore bodies of lead and zinc might exist in depth range 600-1500m below the earth surface along from Yulong, by Yanconglazi, to the Xiangshuigou second-stage syncline at Xiangshuigou.
