Abstract:

The Hulalin gold deposit is located in the north of Erguna ore-forming belt, belongs to the cryptoexplosion breccia type gold deposit related to the porphyry body. The mineralization distribution is featured by the model of onebody withmuhi-type. The orebodies are controlled by cryptoexplosion breccia and faults, Bi、As、Au、Sb、Ag、Pb are obviously enriched and have characteristics of big variation coeficient, uneven distribution. δ³⁴S rangers from -0.2‰～0.8‰ and shows S features of plutonic magmas. The ore-forming materials derive from deep crust or mantle, and the ore-forming fluids derive from the deep magmatic hydrothermal solution. The ore-forming age was 135.5 Ma. The genetic type belongs to the meso-epithermal altered hydrothermal. It will is good prospecting exploration direction for the outside orebodies.
