【摘要】：酒泉东盆地与张掖盆地之间的地质接触关系,至今为止还没有系统的研究。酒泉东盆地与张掖盆地之间的水力联系一直不能做出正确的判断。在分析区域资料的基础上,进行了研究区地质和电性特征研究工作,对比了地质接触关系与电性特征的符合程度,并进一步分析了酒泉东盆地与张掖盆地的地质接触关系和水力联系。电性特征研究结果显示酒泉东盆地与张掖盆地地质接触关系及其电性特征存在明显的一一对应关系。研究结论认为酒泉东盆地与张掖盆地的地质接触关系为北西-南东向的古近系新近系泥岩、砂质泥岩隆起,且该隆起导致酒泉东盆地与张掖盆地在中、南部地下水水力联系比较微弱,而北部基本无水力联系。研究工作为黑河中游地下水水资源量评价、区域生态环境治理和恢复提供了科学的依据。
[Abstract]:The geological contact relationship between Jiuquan East Basin and Zhangye Basin has not been systematically studied so far. The hydraulic relation between Jiuquan East Basin and Zhangye Basin can not be judged correctly all the time. Based on the analysis of the regional data, the geological and electrical characteristics of the study area are studied, and the degree of coincidence between the geological contact relationship and the electrical characteristics is compared. The geological contact relation and hydraulic relation between Jiuquan East Basin and Zhangye Basin are further analyzed. The results show that the geological contact relationship and electrical characteristics of Jiuquan East Basin and Zhangye Basin have obvious one-to-one correspondence. It is concluded that the geological contact relationship between Jiuquandong basin and Zhangye basin is Neogene mudstone and sandy mudstone uplift in the NW-SE direction, and this uplift leads to the middle of Jiuquandong basin and Zhangye basin. The hydraulic relation of groundwater in the south is weak, but there is no hydraulic connection in the north. The research provides a scientific basis for the evaluation of groundwater resources in the middle reaches of Heihe River and the restoration of regional ecological environment.
