FERRUGINOUS DEPOSITS OF LOWER CRETACEOUS AGE IN BORE HOLE RECZ 1

Fragmental iron ores of Neocomian age have been pierced by bore hole Recz 1 situated in the central part of the Mogilno trough (Fig. 1). The oolite-fragmental ore begins the younger sedimentary cycle of the Upper Hauterivian (cyde “b” - according to the oral information by A. Raczyńska).
