江苏省溧阳县透闪石岩研究

Study on the Tremolitite in Liyang County, Jiangsu

江苏省溧阳县小梅岭地区透闪石岩矿床,经研究后认为其矿石主要是钙镁透闪石岩,其中部分岩石微透明,与软玉中的粗玉极相似。本文对透闪石岩的产状、用途做一简介,从矿物学、岩石学方面对透闪石岩矿床进行研究,对其成因进行了初步探讨,认为透闪石岩是典型的接触交代变质作用形成的。

The tremolitite deposit has been found recently in Xiaomeiling area of Liyang County, Jiangsu Province. By studying, the author suggests that the tremolitite body mainly consists of tremolite, and part of the tremolitites are possessed of the limpid feature, which are similar to the rough nephrite.In this paper, the occurence and uses of the tremolitite are introduced simply, and including the study of mineralogy and petrology for the deposit and the initial discussion of its origin. We suggest that the origin of the deposit is the result of a typical contact metasomatic metamorphism.
