摘要
四平山热泉型金矿床产于环太平洋成矿带的完达山脉东麓。金矿体赋存于白垩系上统大塔山林场组和四平山组地层的硅化带中。岩石化学,氢、氧、硫同位素地球化学及围岩蚀变特征等研究表明:该矿床的成矿流体成分中既有大气降水,也有岩浆水的加入,以大气水为主,具有岩浆水与大气降水的双重性质;成矿物质主要来源于地下岩浆热液的分异,少量来源于高背景的围岩;成矿热源来自于岩浆的余热。结合该矿床产出的构造环境建立了该矿床的成矿模型。
Sipingshan hot spring type gold deposit is located in eastern Wandashan of circum Pacific metallogenic belt, and the gold ores are yielded in silicified zones in Datashanlichang and Sipingshan formations of Upper Cretaceous. The research on petrochemistry, H, 0 and S isotopic geochemistry and wall rock alterations indicated that the metallogenic fluid composition in this deposit was meteoric water and magmatic water with dual nature of them. The ore-forming materials mainly came from the differentiation of underground magma, and few from high background wall rocks. The magmatic heat source came from the residual heat of magma. The metallogenic model has been established combined with the tectonic setting.
