摘　　要：夜郎坝构造盆地内多处泉水点及地下水机井水质中锶含量达到国家现行饮用天然矿泉水标准要求,反映了该区具有明显的锶异常显示。通过对水文地质条件及地下水露头(泉点、机井)水化学成份的综合分析研究,表明该区是由多支箕状向斜构造集中交汇构成的环状构造盆地,盆地中侏罗系砂岩地层含富锶膏盐矿物,是形成锶型矿泉水的物质基础,大气降水从盆地边缘和盆地内斜坡地带进入砂岩含水层形成地下水,在径流途中不断溶滤富锶矿物而形成锶型矿泉水;受砂岩与泥岩互层状分布及地下水径流条件控制,矿泉水含水层具有多层性及承压性,越靠近盆地中心地下水径流途径越长、运移速度越慢、溶滤时间越久、富锶含量越高、矿泉水越富集,反之则矿泉水形成和赋存条件越差。The strontium content in the water quality of several spring points and groundwater machine Wells in Yelangba tectonic basin has reached the current national standard for drinking natural mineral water, which reflects that there are obvious strontium anomalies in this area Shaft, water chemical composition, a comprehensive analysis and research indicates that the area is more than by a white shape syncline structure concentrated intersection ring structure in the composition of the basin, basin in Jurassic sandstone formation contain rich cream strontium salt content, is the material basis for the formation of strontium type mineral water, atmospheric precipitation from the edge of basin and basin slope zone into the sandstone aquifer groundwater formation, on the runoff leached rich mineral and strontium Strontium mineral water was formed;Controlled by the interbedded distribution of sandstone and mudstone and groundwater runoff conditions, the mineral water aquifer is multi-layered and confined. The closer to the center of the basin, the longer the groundwater runoff path, the slower the migration speed, the longer the dissolution and filtration time, the higher the strontium-rich content, the richer the mineral water, and the worse the formation and occurrence conditions of mineral water.
