Late Svecofennian sedimentary basins in the crystalline basement of NE Poland and adjacent area of Lithuania: ages, major sources of detritus, and correlations

Krzeminska, Ewa; Wiszniewska, Janina; Skridlaite, Grazina; Williams, Ian


The Precambrian basement of Lithuania and NE Poland, much of which is metasedimentary paragneiss, can be accessed only by cores from deep boreholes. Ion microprobe dating of detrital zircons from samples of these metasediments and the geochemical signatures of the rocks provide new insights into their age and provenance. Detrital zircons from metasediments from Jastrze{ogonek}bna and Mońki have Pb isotopic ages in the ranges 3.14-1.83 and 3.53-1.82 Ga, respectively. Similar results have been...[Show more]
