Sub-Quaternary depression in the Lower Narew Region, its age and origin
A depression in the sub-Quaternary surface, demarcated by Ostrołęka, Ostrw Mazowiecka and Chorzele, reaches in its bottom 80-120 m b.s.l. and possesses also a branch of the same depth. In the Quaternary substrate there are rocks of the Upper Cretaceous, Palaeogene and Neogene. A significant role for...
