摘　　要：朱家洞饰面用大理岩矿是江西省近年来探明的一处大型大理岩矿床,矿床地质特征和控矿因素研究较薄弱。通过分析朱家洞饰面用大理岩矿地质特征,初步探索矿床成因。结果表明:朱家洞饰面用大理石矿赋矿地层为石炭系上统黄龙组,为一套浅海相沉积的白云岩、灰质白云岩、大理岩化灰岩地层;根据其颜色、花纹、光泽度等,判定材料档次为中等;碳酸盐沉积与成矿具有明显相关性。通过分析本区大理岩成矿地质特征,总结大理岩矿床成因,对区内找矿有现实的指导作用。Zhujiadong marble deposit is a large marble deposit discovered in Jiangxi Province in re-cent years.The geological characteristics and ore-controlling factors of the deposit are weak.By analyzing the geological characteristics of Zhujiadong marble mine,the genesis of the deposit is preliminarily explored.The results show that the ore-bearing strata of Zhujiadong facing marble mine is the Upper Carboniferous Huanglong Formation,which is a set of neritic sedimentary dolomite,calcareous dolomite and marbleized limestone strata.According to its color,pattern,gloss,etc.,the grade is determined to be medium.Carbon-ate deposition and mineralization have obvious correlation.By analyzing the geological characteristics of mar-ble mineralization in this area,the genesis of marble deposits is summarized,which has a practical guiding role in prospecting in the area.
