Abstract


DEEPER GEOLOGICAL STRUCTURES BETWEEN THE OLZA AND BIAŁA RIVERS (SOUTHERN SILESIA)

Drilling activities, carried out during post-war times on the area of Cieszyn Silesia, have brought about a fairly exact cognizance of its geological development. The individual bore-hole columnar sections have disclosed a number of structural stages enumerated hereafter, beginning with the lowermost:

1. C r y s t a l l i n e  s u b s t r a t u m, penetrated in bore-hole Puńców (Fig. 1 and 2), is represented by bimicaceous biotic gneisses, as has already been mentioned by K. Konior and A. Tokarski in their paper (1957).

2. Devonian rests, in that same bore-hole, upon an elevated crystalline substratum. In the Devonian, the above mentioned authors distinguished the following stages: the Eifelian, the Givetian, the Frasnian and the Fammenian.
