An extension of the Svecofennian orogenic province into NE Poland: Evidence from geochemistry and detrital zircon from Paleoproterozoic paragneisses
The Precambrian crystalline rocks of northern Poland are known only from deep drill cores. Drilling at Jastrzebna and Monki, in the Mazowsze Domain, NE Poland, has intersected a monotonous sequence of grey paragneisses superficially similar to the paragneisses of the Svecofennian Domain exposed in Sweden and Finland. Petrographically, geochemically and isotopically the rocks from the two regions are in fact almost the same. The Jastrzebna paragneiss is an immature metasediment characterised by...[Show more]
