摘要
呷村地处特提斯－喜马拉雅构造域东缘。呷村银多金属矿床产于晚三叠世义敦古岛弧带的昌台火山－沉积盆地中，矿床规模经勘查证实为超大型。呷村矿床与日本黑矿类比，在构造背景、地质特征、剖面结构及蚀变和矿化分带、矿石类型、成矿机理等方面具有极大的相似性，说明海底喷气－沉积型块状硫化物矿床，在类似的地质构造环境中均具有极大的远景。
Xiacun Ag-polymetallic ore deposit in west Sichuan,China lies in the eastern matgin of the Tethys-Himalayan structural domain.It is confined to Changtai volcanicsedimentary basin controlled by Dege-Xiangcheng deep fracture in Yidun island arc zone in the Late Triassic Epoch.It is a giant Ag-polymetallic ore deposit.Xiacun Ag-polymetallic ore deposit may be correlated with Kurokodeposits in tectonic setting,geological features such as profile structure,alteration and mineralization zonations,ore types and genetic mechanism,etc.This indicates thar large exhalation-sedimentary type massive sulfide deposits may occur in the same trctonicsetting in different times.
