1、硫酸盐类矿物硫酸盐类矿物 硫酸盐矿物为金属元素与硫酸根形成的化合物，占地壳重量的0.1%。组成矿物的阳离子为Ca、Mg、K、Na、Ba、Sr、Pb、Fe、Al、Cu等元素，矿物中常含有水与(OH)-。阳离子以离子键与硫酸根结合，形成的矿物种有：重晶石 BaBaSOSO4 4 ；天青石 SrSrSOSO4 4 ；铅矾 PbPbSOSO4 4 ；硬石膏 CaSOCaSO4 4 ；石膏 CaSOCaSO4 4.2H.2H2 2O O；芒硝 NaNa2 2(H(H2 2O)O)1010SOSO4 4 ；明矾石 KAlKAl3 3SOSO4 4 2 2(OH)(OH)6 6；黄钾铁矾 KFeKFe3 3

2、SOSO4 4 2 2(OH)(OH)6 6;胆矾CuSOCuSO4 4.5H.5H2 2O O。SulfatesSulfates minerals are the compounds of metallic cation with sulfate radicals,which make up by weight 0.1%of the whole Earths crust.Elements serving ascation are Ca,Mg,K,Na,Ba,Sr,Pb,Fe,Al and Cu,there are often H2Oand(OH)-contained.The cations are combined with acid radicals through ionic bonds.There are maked up the minerals:Barite BaSO4 ;Celestite SrSO4 ;Anglesite PbSO4 ;Anhydrite CaSO4 ;Gypsum CaSO4.2H2O;Mirabilite Na2(H2O)10SO4 ;Alunite KAl3SO42(OH)6;Jarosite KFe3SO42(OH)6 ;Chalcanthite CuSO4.5H2O.
