摘要
砂岩是一种沉积岩,广泛用作建筑石材。安徽枞阳麻布山砂岩矿床开发外部建设条件良好。文章通过系统分析矿床地质特征及矿床成因类型,认为矿床成矿物质主要由碎屑岩系河、湖相及沼泽相沉积形成,碎屑物经沉积成岩及与岩浆岩接触热变质形成砂岩和角岩,为内陆湖泊相碎屑沉积岩类矿床。
Sandstone is a kind of sedimentary rock,which is widely used as building stone.The industrial development and external construction conditions of Mabushan Sandstone Deposit in Zongyang,Anhui Province are good.Based on the systematic analysis of the geological features and genetic types of the deposit,it was considered that the ore-forming materials of the deposit is mainly formed by the deposition of clastic rock series river,lacustrine and swamp.The clastic material became sandstone and breccia through sedimentary diagenesis and thermal metamorphism in contact with magma,which is an inland lacustrine clastic sedimentary rock deposit.
