Hornblende bearing varieties bridge the gap over to amphibolites which are in bands and dikes . 含角闪石的变种填补了带状和脉状角闪岩的中间相。
The ore is partly massive and partly disseminated (veinlets and speckles) and there is a halo of disseminated minerals in the surrounding rock . 矿石部分呈块状,部分呈浸染状(细脉状和斑点状),围岩中并有矿物的浸染晕存在。
Study of mining method for inclined thin vein in a copper ore mine 倾斜脉状薄矿体开采方法的研究
The ore body totally shows the characteristics of fan - shaped , which mode of occurrence is 18 - 25 32 - 70 矿体多呈脉状、囊状、似板状、不规则状,总体呈扇形分布,产状18 ? 45 32 ? 70 。
The main ore structure include massive % vein > drusy structure , etc . the second type ore penetrates last type ore in some areas 主要矿石构造为块状构造、脉状构造、晶洞状构造、聚晶镶嵌构造等。
Various shapes that the color is leather , it is vaporific that some become clouds , some are the pulse form , some distribute some forms 色皮的形态各种各样,有的成云雾状,有的为脉状,有的为散点状。
For most of independent gold deposits , especially those of vein type , the ore mineral assemblages and mineral sequences are similar 摘要绝大多数独立金矿床,特别是脉状金矿的矿石矿物组合及其成矿阶段都是十分相似的。
The ore is partly massive and partly disseminated ( veinlets and speckles ) and there is a halo of disseminated minerals in the surrounding rock 矿石部分呈块状,部分呈浸染状(细脉状和斑点状) ,围岩中并有矿物的浸染晕存在。
The structure of mineral stone is priority to dip - dye shape and veins shape ; the framework of mineral is composition with self form , semi - self form , its form , embody composition and false appearance composition in second 矿石构造以浸染状、脉状为主;矿石结构以自形、半自形、它形为主,其次为包含结构、假象结构等。
The dark - gray traction current deposits belong to internal - tide deposits , it develops sandstones and siltsands , and charactered with lenticular , wave , flaser bedding , bimodal cross - bedding and ripple mark 深水牵引流沉积为内潮汐沉积类型,岩性为细砂岩、粉砂岩,以发育透镜状、波状、脉状层理、双向交错层理、波痕等沉积构造为特征。
