摘　　要：南江位于四川盆地东北部通南巴构造带以北的米仓山前缘,归属于扬子准地台北缘,区内地层保留较为齐全,建筑石料用灰岩矿主要赋存于二叠系、三叠系,通过对大地构造背景、地层、构造研究分析及典型矿床特征总结,认为区内有较好的成矿地质条件及较大资源潜力,市场前景较好。Nanjiang is located in the front of Micang Mountain to the north of Tongnanba structural belt in the northeast of Sichuan Basin, belonging to the northern margin of the Yangtze paraphernalia. The strata in the area are relatively complete.Limestone ore for building stone mainly occurs in the Permian and Triassic strata. Through the research and analysis of geotectonic background, stratum, structure and the summary of typical ore deposit characteristics, it is believed that the area has good metallogenic geological conditions, large resource potential and good market prospects.
