摘　　要：本文研究区为江西省浮梁县黄金坑矿区,研究对象为饰面用角岩矿,矿石取名为“玲珑墨玉”,有朴素、庄重、高雅、装饰性能好等特点,属黑色石材高档稀有品种。本文研究矿区饰面用角岩的成矿地质条件、矿床特征、矿体矿石特征及成矿规律,对探索高级饰面石材矿的成因有现实意义。综合分析认为,在新元古代早期经区域与动力变质作用形成了一套以浅变质的板岩、变碎屑岩及变凝灰质岩为特征的地层,发展到燕山中期构造运动期,区域变质作用逐渐消失,相继而至的岩浆活动,使得区内原岩在岩浆温度与挥发分的共同作用下发生热变质,从而形成了堇青石云母角岩。The research area of this article is the Huangjinkeng mining area in Fuliang county,Jiangxi province.The research object is the decorative hornstone,and the ore is named"Linglong Moyu".It has the characteristics of simplicity,solemnity,elegance,and good decorative performance,and belongs to a high-end and rare variety of black stone.This article studies the mineralization geological conditions,deposit characteristics,ore body characteristics,and mineralization laws of decorative hornston in mining areas,which has practical significance for exploring the genesis of high-grade decorative stone deposits.Through comprehensive analysis,it is believed that a set of strata characterized by shallow metamorphic slate,metamorphic clastic rocks,and metamorphic tuffaceous rocks was formed in the early Neoproterozoic through regional and dynamic metamorphism.By the middle stage of the Yanshanian tectonic movement,regional metamorphism gradually disappeared,and subsequent magmatic activity led to thermal metamorphism of the original rocks in the area under the combined action of magma temperature and volatile matter,thus forming cordierite mica hornfels.
