Objawy sylifikacji w skałach węglanowych dolnego cechsztynu w rejonie Lubina i Polkowic

Abstract

SILIFICATION PHENOMENA IN CARBONATE ROCKS OF THE LOWER ZECHSTEIN IN THE REGION OF LUBIN AND POLKOWICE Summary Local silification phenomena have been observed to occur in the carbonate rocks of the Lower Zechstein in the region of Lubin and Polkowice (Lower Silesia). Most probably, this process took place during the later diagenetic phases of the carbonate rocks here. It led to the crystallization of the authigene quartz that developed in the form of porphyroblasts, frequently showing ideal crystallographic forms.
