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

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.
