滩间山金矿床位于柴达木盆地北缘中西段。金矿体产于万洞沟群碳质千枚岩 -片岩地层中 ,受同碰撞造山期构造岩浆活动控制。岩石地球化学特征显示 ,酸性 -偏碱性岩脉中 Au与 As同步富集。矿床中成矿元素之间的相关性表明 ,Au主要来自岩浆热液。稳定同位素组成表明 ,矿床中的硫、碳、铅以及流体中的水主要来自岩浆。矿床地质特征及同位素地质年代学结果显示 ,矿床形成于晚华力西期。 The Tanjianshan gold deposit is located in the central and western parts of the northern margin of the Qaidam basin. The gold ore body is produced in Wancungou carbonaceous phyllite-schist formation controlled by tectonic magmatism in the syn-collision orogeny. Geochemical characteristics of rocks show that Au and As are enriched in acidic-alkaline rocks. The correlation between ore-forming elements in the deposit shows that Au is mainly derived from magmatic hydrothermal fluids. Stable isotopic composition suggests that the sulfur, carbon, lead, and fluids in the deposit are predominantly derived from magma. Geological characteristics of ore deposits and isotope geochronology results show that the deposit formed in the late Warring West period.
