Abstract:The Da'anhe gold deposit in Heilongjiang Province is a typical skarn deposit. However, there was rare research on geochemistry and metallogenic dynamics of the ore-forming rock mass of the deposit previously. This study focuses on the gabbro that is closely related to mineralization. The result shows that the gabbro is Al-rich rock, with enrichment of large-ion lithophile elements(LILE)and depletion of high field strength elements(HFSE). The origin of magma is the mixture of main enriched mantle and continental crust. The diagenetic-mineralization mechanism is closely related to the amalgamation of Jiamusi and Songnen massifs and the subduction of Jurassic Pacific Plate.
