摘要
The Fule Pb-Zn-Cd-Ge-Se-Ga polymetallic deposit is located on the southwestern margin of the Yangtze block, southeast of the Sichuan-Yunnan-Guizhou lead-zinc polymetallic region. It is a medium-sized lead-zinc deposit and contains associated dispersed minerals of Cd, Ge, Se, Ga with commercial values. The reserves of Cd, Ge, and Se reach the standard of a large-scale deposit. The orebodies occur in the interlayer fracture zones of the Permian Maokou Fm. dolomite, with lenticular, layering-like and veined shape. The orebodies are generally 100~1000m long, 50~500m wide and 0.5~25m thick. The ores are of coarse-grained texture and brecciated structure. The ore minerals are dominated by sphalerite and galena with major gangue minerals of dolomite and calcite. The dispersed elements are present in the sphalerite ores. The strong extraction of the ore-originated horizons-Carbonaceous and Permian strata through paleo-brine is responsible for the enrichment of the dispersed elements in this deposit.
