赤铁矿矿石形态
Hematite ore morphology
单晶常呈板状,主要由板面(平行双面)与菱面体等所组成的聚形。集合体形态多样:显晶质的有片状、鳞片状或块状;隐晶质的又鲕状、肾状、粉末状和土状等。赤铁矿根据形态等特征,又有以下的一些名称:具金属光泽的片状集合体者,称镜铁矿;具金属光泽的细鳞片状集合体者,称云母赤铁矿;呈鲕状或肾状的称鲕状或肾状赤铁矿;粉末状的赤铁矿称铁赭石。
Crystal often presents a plate shape, mainly by the surface (parallel sided) and rhombohedral consisting of poly shape. A collection of morphological diversity: explicit crystalline flake, flake or block; cryptocrystalline and oolitic, reniform, powder and earthy etc.. According to the morphological characteristics of hematite, and some of the names of the following: the metallic luster of lamellar aggregates, called Specularite; metallic luster of fine scale like aggregates, called mica hematite; is called the oolitic or kidney shaped oolitic hematite or kidney shaped; powdered hematite called iron ochre.
赤铁矿的形态特征与其形成条件的关系是:一般由热液作用形成的赤铁矿可呈板状、片状或菱面体的晶体形态;云母赤铁矿是沉积变质作用的产物;鲕状和肾状赤铁矿是沉积作用的产物。
The relationship between morphological features of hematite and forming condition is: generally formed by the hydrothermal process of hematite crystalline morphology of plate, sheet or rhombohedral; mica hematite is a product of sedimentary metamorphism; oolitic and kidney shaped hematite is a product of sedimentation.
