【Abstract】 Laerma Se-Cu -U -Ni -Mo -PGE -Au deposit located in the south subzone of the western Qinling is the only gold deposit related with submarine exhalative sedimentation in China. The deposit is controlled by the strata and occurs in the Cambrain Taiyangding group which is about 1000 meters thick and is composed of silicalite, palitic silicanlite and slate. More than eighty percent of the orebodies are present in silicalite. The silicalite controlling orebodies is a product of submarine exhalative sedimentation. The action also lead to the concentration of Au, PGE, Se and other metallogonic elements, which ore principal source of precious metal elements. It is of much significace to discover Se -mineralization in silicalite at present. So, the deposit is typical and unconventional Se-precious metal deposit.
