| 摘 要： | 黑皮、褐皮是软玉子料的常见皮色。文章通过岩石薄片、电子探针、差热分析等多种手段测试,综合判定软玉子料的褐皮是含褐铁矿所致,黑皮是含褐铁矿加有机质所致,这为软玉子料鉴定提供了依据,对子料成因研究也有重要意义。

| Abstract: | Black and tawny cuticles are the most common colors among nephrite gravels.In this paper multi testing techniques including rock slip,electron probe,differential thermal analysis and so on were used to reveal color-causing of the nephrite gravels.The testing results showed that limonite caused the tawny cuticle color and limonite with organic compound caused the black cuticle color,which offers evidence for identifying nephrite gravels and is also of significance in genetic research of nephrite gravels. |
