江西浮梁县黄金坑矿区饰面用角岩矿地质特征及矿床成因OA

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.
