Abstract

Abstract The paper is aiming to determinate the extent of the north eastern arm of Kozłowicka buried valley on the grounds of own re search by means of electrical resistivity tomography- ERT and avail able archival researches. On the Hydro-geological map of Poland, Żyrardów sheet (Felter and Nowicki, 1998a, b) Kozłowicka buried valley was differentiated as an individual hydro-geological unit. The results of the anal y sis show that the ex tent of the structure, defined by its up per boundary, differs significantly from the one suggested on the sheet of Hydrogeological map of Poland. Since there was no data avail able in the north eastern part of the dis cussed arm of Kozłowicka buried valley, the northern boundary was defined only based on avail able geoelectrical sounding profiles (Czerwiñska, 1988; Topolewska, 2015). In order to confirm suggested solution, geoelectrical re search by means of electrical resistivity tomography (ERT) was con ducted. The measurements were per formed along 3 pro files located in the area of interest. The authors would like to point out the need of the us age of ERT in map ping and studying buried structures that might be ground water reservoirs. As a result, one obtains quasi-continuous image of electrical resistivity of the subsurface. Due to the contrast of electrical properties of sediments, it is possible to determine upper and bottom surfaces of buried structures, formed within glacial deposits.

基于地电数据的Kozłowicka隐谷东北部填图

摘要本文在自身研究的基础上，利用电阻率断层成像(ERT)和可利用的档案资料，确定了Kozłowicka隐谷东北臂的范围。在波兰水文地质图上，Żyrardów页(Felter and Nowicki, 1998a, b) Kozłowicka隐谷被划分为一个单独的水文地质单元。分析结果表明，以其上边界定义的构造范围与波兰水文地质图上的建议有很大差异。由于所讨论的Kozłowicka隐谷臂的东北部分没有资料可用，因此仅根据可用的地电测深剖面确定了北部边界(Czerwiñska, 1988;Topolewska, 2015)。为了确定建议的解决方案，利用电阻率层析成像(ERT)进行了地电研究。测量沿着位于感兴趣区域的3个剖面进行。作者想指出，在绘制和研究可能是地下水库的埋藏结构时，需要使用ERT技术。得到了地下电阻率的准连续图像。由于沉积物电学性质的对比，可以确定冰川沉积物中形成的埋藏结构的上下表面。

期刊介绍： Studia Quaternaria is designed to publish scientific works concerning the Quaternary, on local, regional and global scale. Studia Quaternaria is interested in all fields of research dealing with stratigraphy and reconstruction of the past environments, including palaeogeography, palaeoecology, palaeoclimatology, palaeohydrology etc. The journal is also open to studies of natural environmental processes, and to recognition of mechanisms involved in the dynamics of our environment. The clue is that the Quaternary is still ongoing and vivid, and understanding of its past and present development support each other.
