摘要
沉积矿床包括:①海相、湖相沉积的煤、磷、锰、铁、重晶石、石膏、油气等矿床;②风化壳、古风化壳矿床如风化壳铝、锰、镍、粘土、稀有等矿床③外生沉积后在表生条件改造的沉积改造矿床如Hg、Pb、Zn、Sb等硫化矿及碳酸盐岩中菱铁矿等沉积改造矿床。近年来对其沉积微相及成矿机理研究均有较大进展。
The existing sedimentary ore deposits in China include: a. caol, phosphorite, manganese, iron, barite, gypsum, gas and oil and so on in marine and lake facies. b. weathering crust and paleo_weathering crust deposits such as weathering crust types of manganese, nickel, clay, rare metal and paleo_weathering crust types of bauxite and clay; c. sedimentary ore deposits reformed in hypergenic zone such as Hg_, Pb_Zn_, Sb_sulfide deposits , and siderite deposits in carbonate. Recently, a great progress has been gotten on the study of micro_facies and mineralization mechanism of the deposits.
