鲁西北地区理疗热矿水的形成条件及找矿靶区

鲁西北地区赋存发育碳酸盐岩类裂隙-岩溶型与砂岩类裂隙-孔隙型2种理疗热矿水,碳酸盐岩类裂隙-岩溶型理疗热矿水主要为氟·锶水;砂岩类裂隙-孔隙型理疗热矿水主要为锶水和溴·锶水。根据对理疗热矿水形成条件的分析,研究区内的鲁西地块阳谷-齐河凸起与坳(凹)陷区内的顶部风化壳岩溶发育的基底凸起(潜山)是碳酸盐岩类裂隙-岩溶型理疗热矿水的找矿靶区;华北坳陷区内深大断裂及坳(凹)陷边缘较大断裂附近的次级构造发育区是砂岩类裂隙-孔隙型理疗热矿水的找矿靶区。

Formation conditions and prospecting targets of physiotherapy geothermal mineral water in northwest Shandong Province

Abstract: There are two kinds of physiotherapy geothermal mineral water developed in the northwest of Shandong Province, one referring to carbonate fissure?karst type and the other referring to sandstone fissure?pore type. The carbonate fissure?karst water belongs to Sr·F water, whereas the sandstone fissure?pore water belongs to Sr water and Br·Sr water. According to the analysis of the formation conditions of geothermal mineral water, the authors hold that the weathering crust and karst well?developed buried hill at the top of the Yanggu?Qihe uplift and depression are favorable prospecting target areas for carbonate fissure?karst geothermal mineral water, whereas the secondary structural zones near the deep faults within the North China depression and on the edge of the depression are favorable prospecting target areas for sandstone fissure?pore geothermal mineral water.
