%X The Da Higgan Mts. is an impotent polymetallic mineralized zone in the north part of China. This paper discusses the metallogenetic system of the Da Higgan Mts. according to the source of its metallogenic materials and its tectonic settings. Sr-Nd-O-Pb isotopic researches show a deep source of the metallogenic materials in the Da Higgan Mts., and studies on composition of the Late Mesozoic crust-mantle migmatitic granitic rocks in the Da Higgan Mts. and their structural environment indicate that they are A-type granitic rocks formed in an intraplate and non-orogenic extensional environment. Understanding of the Mesozoic metallgenetic characteristics of the Da Higgan Mts. is deepened through comparison with Nanling granitic rocks and its mineralization. The deep structures of the Da Higgan Mts. further reveal its tectonic background of lithogenesis and mineralization.
