摘要

The Shanhou lead-zinc deposit is located in Gaoyang Township of Shunchang County, Fujian Province. It occurs in green schist of the Dongyan Fomaation. Presently, 12 Pb-Zn orebodies and 3 low-grade Pb-Zn ore-bodies have been found there. The ore-bodies occur as stratified or stra- told beds and lentieular type in diopside or tremollte of the Dongyan Formation between faults FI3 and FI4. The grade of Pb plus Zn is 7.21% , and the amount of 332 and 333 reserve is 124.6 thousand tons, reaching the medium-sized deposit. The study indicates that the lead-zinc deposit is controlled by greensehist association of the Dongyan Formation, subjected to superimposed reformation of hydrothen＇nal solution. It belongs to submarine volcano - sedimenta17 metamorphic （hydrothermal modification） massive sulfide deposit. And we summarize the prospecting indicators, including the greenschist association of the middle-late Proterozoie Dongyan Formation, henomenon of black limonite spots that are often seen after oxidation of ground orebodies, chloritization, epidotization, pyritized and silieification alteration of Surrounding rock, and geophysical and geochemical anomalies by the studies of the stratum, structure, rock mass and surrounding rock alteration on the Shanhou deposit. This study may have guiding significance for the similar deposits in Fujian Province and South China.
