摘要
The authors discussed the geological properties of sedimentary transformation deposit in Youxi County of Fujian Province,summarized three types of deposit modes:Meixian-type stratiform Pb-Zn(Ag) polymetallic deposit;Xiaoban-type Au deposit of brittleductile shear zone mode and Longmenchang type Pb-Zn(Au-Ag) polymetallic deposit.In combination with element properties,the authors depicted the structural evolution properties and metallogenic mechanism,put forward the ore exploration orientation for sedimentary transformation deposit in Youxi County.
