Abstract：The Neoproterozoic-Early cambrian Luomahu group metamorphic rocks, outcropped in Guliku gold field, Daxinganling Ridge, consist of gneiss, schist, metadolerite, marble and slate,which belong to low greenschist, high greenschist and low amphibolke facies. Restoration of original rocks shows intermediate-basic and acid-intermediate volcanic rocks, fragmental rocks, siltstone, sandstone and limestone. Theain mineralizing elements, i.e., Bi, Au, Ag and Hg are relatively richer than those in continental crust. After ductile shearing, there is apparent enrichment for Au, Ag and Bi, As well as As and Sb. Thus, it is concluded that the Luomahu group metamorphic rocks should be the provenance of ore and the ductile shearing concentrates the mineralizing elements such as Au, Ag,etc.
