Abstract
The north-western area of the Moscow region is located in the central part of the Moscow syneclise, on the southern slope of the Klin-Dmitrov ridge. Quaternary glacial loams dominates in the upper part of the geological section. Hydrogeologically, the Moscow region belongs to the Moscow artesian basin. Upper water supply, groundwater and aquifers are widely developed at the depths of 5–15 m. The authors set the following geological and hydrological objectives: clarifying the geological structure of the upper part of geological section, groundwater level mapping, evaluation of geophysical and soil properties. Glacial deposits are significantly different from host rocks in terms of density, electrical resistivity and elastic waves velocity, so the following geophysical methods were selected for their study: seismic prospecting, electrical exploration and radiometry. As a result of the study, a physical-geological model was constructed with refractive and geoelectric boundaries, which are compared with the roofs of uneven-aged moraine loams.
