    鄂爾多斯盆地是我國水資源十分短缺的大型內陸盆地之一，自五十年代以來，已開展了大量地質與水文地質工作，積累了豐富的水文地質資料和水化學資料，如何有效地管理和充分利用現有水化學資料，運用先進的技術手段，在前人資料的基礎上進行白堊系地下水水化學分佈規律研究，以利進一步掌握盆地地下水補、徑、排規律，充分發揮地下水資源的潛力，合理開發利用水資源，促進該區社會經濟發展和生態環境保護、治理，是一項非常緊迫且意義重大的工作。
  3. The palaeogeographic research indicate that the palaeogeographic outline of the study area recorded the evolution from a sedimentary basin in which the shallow - water carbonate platform sediments and deep - water terrigenous clastic submarine fan developed from southeast to northwest and northeast during the late triassic through a submarine sheet - like model composed of deep - water sandy turbidite and fine - grained turbidite during the early jurassic to a terrigenous clastic barrier coast during the middle and late jurassic and finally to the coal - bearing delta sediments during the late cretaceous

    古地理分析表明，研究區晚三疊世古地理輪廓是一個從東南向西北和東北方向由淺水碳酸鹽臺地及深水陸層海底扇沉積共同發育的沉積盆地；早中侏羅世，演變成為一個由深水砂質濁積巖和細屑濁積巖組成的水下席狀體沉積；進入中晚侏羅世，其古地理表現為一個陸屑淺海有障壁海岸；到了晚白堊世，研究區表現為以含煤沉積為特徵的三角洲相沉積。
