摘要
2:3的蒙皂石-云母间层矿物产于含锰碳酸盐矿物中,与方解石、钙菱锰矿、菱锰矿、菱铁矿、黄铁矿、黄铜矿和锐钛矿共生。矿物呈片状和不规则粒状,颜色呈灰、灰白色和浅黄色,条痕灰白色。显微硬度78kg/mm^2、摩氏硬度1.5。比重2.58。比磁化系数3.35×10^(-6)C·G·S·M·cm^3=/g。主要X射线粉晶线是11.39(100),5.06(87),4.48(81),3.28(70)。矿物的红外吸收谱特征为:3600—3700,1000—1050,540,490cm^(-1),此外还对该矿物作了差热分析。
The 2:3 interstratified mineral was found in Mn-bearing carbonate minerals, and associated with calcite, kuthahorite, rhodochrosite, siderite, pyrite, chalcopyrite and futile.The mineral is lamellar or irregular granular in shape. It is grey, greyish-white or light yellow in colour, with no cleavage. It may be opaque or moderately transparent depending on grain size. Streak greyish-white,H(Vickes)=78kg/mm^2,H(Mohs)=1.5,D(specific gravity)=2.58,K(specific susceptibility=3.35×10^(-6) C·G·S·M·cm^3/g,The strongest lines in the partially indexed X-ray pattern are: 11.39(100), 5.06(87), 4.48(81), 3.28(70),……Its infrared absorption bands appear at 3600—3700, 1000—1050, 540, and 490cm^(-1). The DTA curve for this mineral is also presented in this paper.
