Oznaczenia radiowęglowe zbiorowych grobów ciałopalnych trzcinieckiego kręgu kulturowego z Polski Środkowej

The article presents new radiocarbon determinations obtained for collective graves from the Trzciniec cultural circle (TCC) in Central Poland. The dated graves were associated with the Konstantynów group and belong to the late phase of the TCC. As a result of the research carried out on this form of burial, it was possible to distinguish two types of graves and locate their concentrations in Central Poland in the zone where the materials of the Konstantynów group occur. The established dates, together with the technological and stylistic analysis of ceramic materials, make it possible to determine two time horizons in the late phase of the Trzciniec culture circle.
