【摘要】 <正> 菱铁矿有产于伟晶岩脉、热液矿床及沉积矿床中等多种产状。目前,我国对许多矿床内菱铁矿的成因有沉积论、热液论和沉积热液改造论等不同观点的争议。本文对河南某斑岩型钼-多金属硫铁矿床中菱铁矿的成因标型特征研究初步成果作一简介。更多还原

【Abstract】 This paper deals with some problems of basic theory on the typomorphic characteristics of siderite.The results of the study of typomorphic characteristics of siderite from a certain polymetal-sulphur ore deposit of Henan Province are reported.Siderite in this deposit provides some information on magmatogene hydrothermal origin.The chemical characteristics of siderite will conduce to the identification of deposit genesis between sedimentary and magmatogene hydrothermal origin.更多还原
