摘　　要：甘肃省已发现的大中型白云岩矿主要集中分布在境内东西部区域,品质较佳,多用在冶金、冶镁、玻璃和建材等领域。白云岩在时间分布上以蓟县纪和前长城纪为主,次为长城纪、寒武纪和二叠纪;空间上主要集中分布在北祁连弧盆系、中祁连岩浆弧、鄂尔多斯西缘裂陷带、北秦岭弧沟系及南秦岭裂陷大陆边缘等构造单元中。本文收集、研究分析全省已发现的白云岩矿床,在总结其分布特征和成矿规律的基础上,圈定了3个成矿远景区,为今后白云岩的找矿、勘查等提供参考。The large and medium-sized dolomite deposits discovered in Gansu province are mainly concentrated in the eastern and western regions,with good quality and mostly used in metallurgy,magnesium smelting,glass and building materials industries.The temporal distribution of dolomite is mainly dominated by the Jixian and Pre Great Wall periods,followed by the Great Wall period,cambrian period,and permian period;Spatially,it is mainly concentrated in tectonic units such as the north Qilian Arc basin system,the central Qilian magma Arc,the western margin of the Ordos rift zone,the north Qinling arc gully system,and the continental margin of the south Qinling rift.This article collects,studies,and analyzes the discovered dolomite deposits in the province.Based on summarizing their distribution characteristics and mineralization laws,three prospective mineralization areas are delineated,providing reference for future dolomite exploration and prospecting.
