高松山金矿床位于中国东北小兴安岭矿集区,赋矿围岩主要为下白垩统安山岩等中基性火山岩.矿体受张性断裂的控制,呈高角度脉状产出.矿石中金属矿物主要为黄铁矿和少量的黄铜矿、方铅矿、闪锌矿、自然金和银金矿.蚀变矿物组合为石英-冰长石-绢云母(伊利石)-方解石.矿石构造主要为细脉-网脉状构造,次为角砾状构造、浸染状构造、叶片状构造等.成矿流体具有低温、低盐度的特征,主要来源于大气降水,C-S-Pb同位素组成表明成矿物质主要来源于赋矿火山岩或岩浆气体.通过与东北地区其他典型的中生代浅成低温热液型金矿床特征进行对比,地质地球化学特征支持高松山金矿床属于典型的低硫化型浅成低温热液金矿床.
Gaosongshan gold deposit is located in the Xiaoxing'anling Ore Concentrating District,Northeast China.Lower Cretaceous andesite is the main host rock.Ore bodies occur as high angle veins controlled by tensile faults.Metallic minerals consist of pyrite,less chalcopyrite,galena and sphalerite,native gold and electrum.Alteration mineral assemblages are quartz,adularia,sericite (illite) and calcite.Ore structures mainly include veinlet-stock-work structure,brecciated structure,disseminated structure and bladed structure,etc.Ore forming fluids are low-temperature,low-salinity and of meteoric water origin.C-S-Pb isotope compositions show that ore hosting volcanic rocks or magmatic vapor provided ore-forming materials.By comparing with the geological geochemical characteristics of typical Mesozoic epithermal gold deposits in northeastern China,it is evidenced that the Gaosongshan gold deposit is a typical low-sulfidation epithermal gold deposit.
