摘要/Abstract

摘要： 最近在福建南平地区发现软玉，其质地细腻，白色－浅绿色，ＲＩ＝１．６１￣１．６２，密度２．９７９￣２．９８９ｇ／ｃｍ＾３，硬度６．０￣６．１，矿物成分较为简单，为透闪石，局部含少量透辉石包裹体。化学成分接近于透闪石的理论成分，ＦｅＯ的含量很低，是一种品质较好的玉雕材料。

Abstract: The nephrite was first found in Nanping, Fujian recently. The primary studies show that Nanping nephrites have white to light green color, RI of 1.61-1.62, density of 2.979- 2.989 and hardness of 6.0- 6.1. The nephrites consist simply of tremolite, but sometimes some diopsides. The chemical compositions of the nephrites are close to the theoretical value of tremolite, with low content of FeO. Comparing to XinJiang nephrites they have a stronger 3671cm-1 hand in their IR spectra, which might indicate their lower content of F. Nanping nephrite occurred in Precambrian metamorphic rocks, marble and diopside marble, and was formed through the regional metamorphism.
