| 摘 要： | 鄂尔多斯盆地周边岩溶区岩溶含水岩组主要由奥陶系和寒武系灰岩组成,岩溶发育受层状裂隙和构造裂隙控制,主要分布在盆地的东缘、南缘和西缘。文中通过对鄂尔多斯盆地周边岩溶区碳酸盐岩分布特征和埋藏条件的分析,提出3种岩溶发育模式:斜坡顺层岩溶发育模式、裂谷逆层岩溶发育模式和逆冲断层岩溶发育模式,对3种模式下岩溶发育的地质构造特点、水动力及水化学条件、岩溶发育特点进行分析和总结。初步探讨了3种模式下岩溶地下水资源量和开发利用规划。结果表明鄂尔多斯盆地周边岩溶地下水具有巨大的开发潜力。

| Abstract: | The karst water-bearing layers are composed of Ordovician and Cambrian limestones in the peripheral area of Ordos Basin,and the development of karst is under the control of stratiform cracks and structural fractures,mainly distributed in the east,south and west margins of the basin.Based on the analysis of carbonate rock distribution and burial condition in peripheral area of Ordos Basin,we put forth three modes of karst development: the slope-bedding karst development,the rift valley-reversing karst development and the thrust belt karst development.In present paper we analyze and summarize the geological structure characteristics,hydrodynamic and hydrochemical conditions and the karst development characteristics in the three modes of karst development and discuss the karst groundwater resources development and utilization planning in the three modes.The results show that the karst groundwater has great development potential in the peripheral area of Ordos Basin. |
