摘要
根据韩国白玉的电子探针分析发现,韩国白玉富含FeO,贫MnO2,从而使得其外观上有一种泛青色调。在偏光显微镜下观察发现韩国白玉具有似变斑晶结构,透闪石呈放射状、纤维状、纺锤状、纤维束状分布,其粒度明显分为两组:一组为较大的变斑晶,其颗粒的大小范围在0.1×0.2~0.4×0.8(mm),大部分为0.2×0.4(mm);另一组为基质部分,其透闪石呈纤维状交织结构,粒度小于0.05mm。该种结构白玉质地较为粗糙,外观上也可见到白色的颗粒呈点状较均匀的分布。
According to the electron microprobe analysis,the white nephrites with rich FeO and depleted MnO2 from Korea will be greenish.It has resembling porphyroblast texture in which the tremolites present the radial,fibrous,fusiform and fibrous bundle distribution,their granularity obviously divides into two groups.The one is the bigger porphyroblast which size is from 0.1mm×0.2mm to 0.4mm×0.8mm,most of them are 0.2mm×0.4 mm.Another group is groundmass which tremolites present as fibrous pilotaxitic texture and the granularity is smaller than 0.05mm.The texture of this white nephrites is rough and the white pellets distribute evenly like punctate in appearance.
