WYNIKI BADAŃ PALEOMAGNETYCZNYCH OSADÓW JEZIORNYCH Z PROFILU CZARNUCHA (RÓWNINA AUGUSTOWSKA, PÓŁNOCNO-WSCHODNIA POLSKA)

Abstract

THE RESULTS OF PALAEOMAGNETIC INVESTIGATIONS OF LACUSTRINE DEPOSITS FROM THE CZARNUCHA SECTION (AUGUSTÓW PLAIN, NORTHEASTERN POLAND)Abstract. Paleomagnetic analysis was performed on 51 core samples from the Czarnucha borehole. The lacustrine deposits were mostly remagnetized as a results of diagenetic processes leading to the formation of secondary magnetization carries. Single samples of negative inclination, found mainly in the lower portion of the section, most likely represents the original palaeomagnetic record. Their presence can indicate that at least part of the sequence was deposited during the Matuyama chrone of reverse magnetization.
