Egzotyk granitoidowy z warstw jaklowieckich kop. "Marcel"
Abstract
GRANITOID EXOTIC FROM JAKLOWIECKIE BEDS EXPOSED IN THE "MARCEL" MINE
Summary
Granitoid exotic identified as tonalite on the basis of mineralogical analyses was found at the level 713 in the Marcel mine (Upper Silesian Coal Basin). It resembles tonalites from Bachowice (7) in mineral chemical composition. It is assumed, therefore, that the material for Jakłowieckie Beds in the Rybnik region came from the crystalline massif of the Precarpathians.
