Geological Characteristics and Ore-probing Future of Silver-lead Multi-metallic Deposit in Jiaonan City, Shandong Province

Qibaoshan area locates in north edge of Jiaonan tectonic belt with a complicated geological structures. Through the work in a year, multi-metallic deposit which silver and lead are its major metals are found. Silver and lead are its major useful compositions, accompanying with fluorite, cooper and a little gold. Silicatized tectonic fractured belt, quartz vein and fluorite-quartz vein are ore-probing symbol. Two sides of Shanzhou fault and Weideshan wuperunit in late Yanshan period are major ore-probing areas, and there is a good ore-probing future in this area.
