新疆若羌县沟口泉金矿矿床成因探讨

Genesis of gold deposit in Xinjiang County of Ruoqiang ditch Stephen

位于新疆若羌县城东偏北280 km处。大地构造位于阿尔金古陆块和红柳沟-拉配泉奥陶纪裂谷,构造复杂,岩浆岩发育。矿体产于奥陶系中上统拉配泉群(O_(2-3)L)的凝灰质粉砂岩中。通过大量深入细致的地质勘查工作和研究,对控矿因素和矿物共生组合特征等进行分析,并对矿床成因进行了初步分析。

Xinjiang county is situated in the east of Ruoqiang North 280 km. Located in Altun tectonic block and Hongliugou Lapeiquan Ordovician rift, complex structure, magmatite development. The ore bodies are found in the middle and Upper Ordovician(O_(2-3)L) of the middle and Upper Ordovician. Through a large number of in-depth and detailed geological exploration work and research, the ore controlling factors and the characteristics of mineral assemblages were analyzed, and the causes of the deposit were analyzed.
