Abstract

NOTES ON THE STRATIGRAPHY OF THE CRYSTALLINE SUBSTRATUM OF NORTHEASTERN POLANDThe Precambrian substratum of northeastern Poland is nowhere exposed on the surface. Thus far, it has been ascertained in 9 drillings. In bore hole Pisz, pink quartzites were penetrated and, underlying them, gabbro with syenite; in bore hole Ostrów Mazowiecka - pink quartzites, with granitoids underneath; in bore hole Ełk - syenites; in bore hole Krynki - biotite parachists; in bore hole Suwałki - anorthosites, in bore hole Sokółka 1 - phyllite schists with ophiolites underneath. The latter are deposited on gneisses and migmatites; in bore hole Sokółka 2 are gneisses and migmatites, in bore hole Sokółka 3 gneisses and migmatites, in bore hole Wisznica granitoids and quartz diorites.AlI these rocks may be divided into: A -quartzite rocks, and B - intrusive and metamorphic rocks.
