Abstract

GEOLOGICAL CONDITIONS OF THE OCCURRENCE OF MAGMATIC ROCKS IN MRZYGŁÓD NEAR ZAWIERCIE ŚLĄSKIE (LOWER SILESIA)

PALAEOZOIC DEPOSITS

In the substratum of Triassic rooks, at a depth beginning with 80 m. in bore-hole Nr 10 to over 200 m. in bore-hole Nr 4, a series of grey to black schists have been found. They are strongly compressed, hydrothermally transformed, silicified, albitized and chloritized.

Side by side with these hydrothermally metamorphosed schists lying Palaeozoic deposits consist of black sandstones and of grey, brown and green roofing slates.
