Abstract:

Hulalin gold deposit is a middle-scale gold deposit located in north part of Eergunam ineralization belt, and the explosive breccia is the host rock. The deposit locates between North China plate and Siberia plate, is one of the growth area of porphyry type and explosive breccia type gold deposit. Mineralization age of gold deposit is 135Ma, mineralized breccia has the characteristics of typical crypto-explosion breccia. Mineralization has close relationship with the explosive breccia in space, time and genesis. The gold deposit has got the petrochemical characteristics that δ34S is from -0.2‰to 0.8‰, and Scharacteristics of deep-seatedmagma. The characteristics of S and Pb isotope, fluid inclusion and REE show that metallogenic material is from deep crust ormantle, and metallogenic fluid mainly is deep magmatic hydrotherm. Hulalin deposit is a typical crypto-explosive breccia type gold deposit.

Key words: Eerguna metallogenic belt, Crypto-explosion breccias, Petrolchemistry, Hulalin gold deposit, Inner Mongolia
