锡铁山多金属矿床位于青海柴达木盆地东北边缘埃姆尼克山南端。该矿床规模巨大,其中伴生有贵金属和稀有分散元素。多年来,一直认为该矿床的形成与岩浆热液有关。最近笔者根据野外观察,结合地质构造、控矿因素及硫同位素资料等,认为该矿床与岩浆活动无明显关系,而与碳酸盐岩和构造关系较密切,并受后期地质作用的改造,为一受构造、地层岩性双重因素控制的改造型层控矿床。现简要叙述如下,不当之处,望批评指正。
Xishan Mountain polymetallic deposits located in the northeast edge of Qaidam Basin in Qinghai Emine Hill southern tip. The deposit is huge, with associated precious metals and rare dispersing elements. Over the years, the deposit has been considered to be associated with magmatic hydrothermal fluids. Recently, based on the field observation, combined with the geological structure, ore-controlling factors and sulfur isotope data, the authors believe that the deposit has no obvious relationship with magmatism, but is closely related to carbonate rocks and tectonism, A subject to the formation, stratigraphy and lithology dual factor control of the modified stratabound deposit. Is now briefly described below, inappropriate, hope to criticism and correction.
