| Abstract: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 shearing 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. |
