| 摘 要： | 采用常规宝石学测试、偏光显微镜观察与电子探针(EPMA)分析对具有矿化分带的韩国春川软玉进行研究。结果表明,春川软玉主要矿物组成为透闪石,其次有透辉石、方解石、白云石、滑石等。矿化分带分为大理岩带、蚀变带、软玉+蚀变带、软玉带,是白云质大理岩经过多次交代与变质作用形成的。

| Abstract: | The Chuncheon nephrite of South Korea is becoming more and more common on Chinese market. It is usually called the Chuncheon nephrite or Chuncheon jade, and on the market it is often referred to as "Han Guo Liao". In this study, polarizing microscope and electron microprobe (EPMA) analysis were used to study Chuncheon nephrite samples with the emphasis placed on the mineralized zone. The results show that the major mineral component of Chuncheon nephrite is tremolite, followed by diopside, calcite, dolomite and talc. The mineralized zone is classified into marble zone, alteration zone, nephrite+alteration zone and nephrite zone. The mineralized zone of the Chuncheon nephrite was formed by metasomatism and deformation of the dolomitic marble zone. |
