摘　　要：广西壮族自治区(简称广西)泥盆系岩层广泛出露,其中,唐家湾组灰岩矿体内部结构简单,主要组分CaCO_(3)品位高且稳定,在走向和倾向上变化小,有害组分含量均很少,满足工业指标要求,矿石可正常破碎开采。本文结合平南县狼狗窝制碱用灰岩矿的地质特征和矿体特征,分析矿床成因,明确找矿方向。研究认为,该矿床由浅海开阔台地相化学沉积而成,属陆台型浅海相碳酸盐建造,广泛分布于平南县-桂平市一带,找矿前景较好。本研究为广西泥盆系唐家湾组制碱用灰岩矿找矿提供参考。The Devonian strata in Guangxi Zhuang Autonomous region(referred to as Guangxi)are widely exposed,among them,the internal structure of the Tangjiawan Formation limestone ore body is simple,and the main component CaCO,has a high and stable grade,with little variation in direction and dip,and the content of harmful components is very low,meeting the requirements of industrial indicators,and the ore can be crushed and mined normally.Based on the geological characteristics and ore body characteristics of the limestone ore used for alkali production in Langgouwo,Pingnan county,this paper analyzes the genesis of the deposit and clarifies the direction of exploration.Research suggests that the deposit is formed by the chemical deposition of shallow sea open platform facies,belonging to the continental platform type shallow sea carbonate formation,and it is widely distributed in the Pingnan County-Guiping city area and has good prospecting prospects.This study provides a reference for the exploration of alkaline limestone deposits in the Tangjiawan Formation of the Devonian in Guangxi.
