Abstract

The present study is aimed at characterizing the subsurface geological and tectonic structure in Deir El-Adas area, by using Vertical Electrical Sounding survey (VES) and hydrogeological investigations, in order to determine the causes of the failure for the majority of the wells drilled in the area. The survey data was treated in three different approaches including direct VES inversion, pseudo-2D method and horizontal profiling, in order to maximize the reliability of the data interpretation. The results revealed the presence of a local faulted anticline structure at the top of the Paleogene formation, underneath the basaltic outcrops where Deir El-Adas village is situated. The appearance of this subsurface anticline structure has complicated the local hydro-geological situation, and most likely led to limitation of the groundwater recharge in the area. Moreover, the performed piezometric and discharge maps indicated the presence of a notable groundwater watershed, in addition to feeble water productivity of the wells drilled adjacent to Deir El-Adas, mostly related to the subsurface geological and tectonic settings in the area.

利用垂直电测深表征叙利亚耶尔穆克盆地Deir El-Adas地区水文地质和构造环境
本研究旨在通过垂直电测深(VES)和水文地质调查,描述Deir El-Adas地区的地下地质构造特征,以确定该地区大部分钻井的失效原因。为了最大限度地提高数据解释的可靠性,对调查数据进行了三种不同的处理方法,包括直接VES反演、伪2d方法和水平剖面。结果显示,在古近系地层顶部,在Deir El-Adas村所在的玄武岩露头下方,存在一个局部断裂背斜结构。这种地下背斜构造的出现使当地水文地质情况复杂化,很可能导致该地区地下水补给受到限制。此外,所进行的压力测量和流量图表明,除了在Deir El-Adas附近钻探的井的水生产力很弱之外,还存在一个显著的地下水分水岭,这主要与该地区的地下地质和构造环境有关。
