    西藏勒青拉铁矿床地质特征及其找矿意义

    Geological characteristics of the Leqingla iron deposit, Tibet, and their prospecting significance

    • 摘要: 提要:笔者对勒青拉铁矿床形成的地质背景、矿床地质特征、成矿机制和找矿前景进行了研究。研究结果表明,矿床位于冈底斯岛弧造山带东段北矿带,矿体产出部位严格受碳酸盐岩层位及其层间破碎带的控制,矿体主要为层状。容矿岩石主要为矽卡岩、矽卡岩化灰岩。矿石类型简单,主要为磁铁矿矿石。矿化富集与喜马拉雅早期居布札日花岗闪长岩密切相关,矿床类型属矽卡岩型矿床。勒青拉铁矿床潜在资源量巨大,外围地区具有相同类型铁矿床的找矿远景。

       

      Abstract: Abstract:The paper discusses the geological settings, geological characteristics, metallogenic mechanism and ore prospects of the Leqingla iron deposit. The Leqingla iron deposit is located in the northern ore belt of the eastern segment of the Gangdise arc orogen and the orebodies mainly occur in the stratiform shape and are controlled by carbonate rock formations and interformational fracture zones. The host rocks are mainly skarn and skarnized limestone. The ore types are simple, dominated by magnetite ore. The enrichment of the mineralization is closely related to the early Himalayan Jubuzhari granodiorite, and the deposit is of skarn type. The potential resources of the Leqingla iron deposit is huge and there are ore prospects of the same type of iron deposit in the surrounding areas.
