| Abstract: | This paper analyzed the ore features and metallogenic stage of the deposit through field geological survey and optical microscope.About 53 kinds of minerals have been identified in Longtan gold deposit.The ore structure is mainly crystalline structure and metasomatic structure,followed by solid solution separation structure and crushing structure.Ore structures mainly include vein structure,network vein structure,disseminated structure,lumpy structure and brecciated structure.The embedding type of natural gold is mainly inclusion gold,followed by fissure gold and interstitial gold.Through analysis,the metallogenic stage is divided into hydrothermal stage and supergene stage,which is divided into five endogenetic stages and one supergene stage. |
