Geochronology of the Pleistocene deposits exposed at Wąchock, northern part of the Holy Cross Mts

Abstract

The determinations of absolute age (by means of the thermoluminescence method) of the Pleistocene deposits exposed at Wąchock, northern part of the Holy Cross Mts, Central Poland, are presented. The oldest deposits, the sub-till fluvial sands, dated for 352 000 BP, represent the end of the Mazovian Interglacial (Mindel II/Riss I). Supra-till silts, dated for 245,000±45,000 BP deposited at the beginning of the Lublinian Interglacial (Riss I/Riss II). The overlying cover sands, dated for 142,550±3,650 BP, represent a younger part of the Vartanian Glaciation (Riss II). The loesses of the uppermost part of the section, dated for 42,000±1,500 BP, 24,087±2,587 BP, and 15,830±1,830 BP, are related to the Middle and the Late Vistulian (Würm) Glaciation.
