Sažetak
The Navamuño depression, located in the high sector of the Cuerpo de Hombre valley (Sierra de Béjar), was partly occupied by a glacier during the Late Pleistocene. The basin is a ~14 Ha pseudoendorheic depression with boundaries defined by fault lineaments and the left lateral moraine of the Cuerpo de Hombre paleoglacier. The geometry of the base of the basin and the thickness of sediments that contain were studied together with the relationship of these deposits with the structural elements. Eight bi-dimensional profiles of electrical resistivity tomography were carried out supported by nine vertical electrical sounding logs. Although heterogeneous, the maximum thickness of the deposit infilling the basin is higher than approximately 20 m in some sectors, with three units under the urficial soil. The depression is interpreted as a basin filled with fluvioglaciar and fluviotorrential deposits with episodes of local shallow pond/bog peat sedimentation.
