辽宁岫岩软玉砂矿 (又称河磨玉矿 )是原生软玉矿的次生砂矿床。其玉石质地细腻 ,光泽滋润。作为装饰文化的宝玉石资源 ,越来越受到人们的青睐。岫岩软玉砂矿的发现和深入研究 ,不仅具有经济意义 ,还具有宝石学、考古学等多方面的意义。本文认为岫岩软玉砂矿属冲洪积类型 ,是第四世纪以来构造活动和气候环境的产物。河磨玉皮壳层是表生作用下元素迁移和交换的结果。本文还对宝石资源的开发利用与保护提出了建议。
Liaoning Xiuyan soft jade ore (also known as river grind jade ore) is a native secondary jade ore mineral deposits. Its delicate jade texture, gloss moisture. As a decorative gem of cultural resources, more and more people of all ages. Xiuyan soft jade ore discovery and in-depth study, not only of economic significance, but also has gemmological, archaeological and other aspects of significance. This paper argues that Xiuyan nephrite ore belongs to the alluvial-alluvial type and is the product of tectonic activities and climate and environment since the fourth century. River mill jade shell is superficial migration and exchange of the results. This article also puts forward suggestions on the development, utilization and protection of gem resources.
