摘　　要：为详细研究筠连县上大山嘉陵江组建筑石料用灰岩地质特征,通过勘查研究及试验分析等方法对其岩石矿物学特征和物理性能特征进行研究。结果表明:矿石矿物组分以方解石为主,矿石的抗压强度(水饱和)、坚固性、压碎指标、硫酸盐及硫化物、碱活性等指标能达到建筑用碎石I级品要求。可见研究区嘉陵江组建筑石料用灰岩矿石能满足建筑用石料一般要求,对该地区同类矿产勘查、开发利用提供参考。To conduct a detailed study on the geological characteristics of limestone for construction aggregate in the Jialingjiang Formation of Shangdashan,Junlian County,this paper investigates and analyzes its petrological and mineralogical characteristics and physical performance characteristics through exploration research and experimental analysis.The results show that the ore mineral components are mainly calcite.The compressive strength(water saturated),firmness,crushing index,sulfate and sulfide,alkali activity and other indicators of the ore can meet the requirements of grade I crushed stone for construction.It can be seen that the limestone ore for construction aggregate in the Jialingjiang Formation in the study area can meet the general requirements for construction aggregate and provide a reference for the exploration,development and utilization of similar minerals in this area.
