Abstract

NEW DATA ON PETROGRAPHY OF THE ROTLIEGEND ROCKS IN THE WESTERN PART OF THE FORE-SUDETIC MONOCLINEAbstract. The paper presents the results of studies of Rotliegend rocks from four boreholes located in the western part of the Fore-Sudetic Monocline. Standard petrographic (microscopic and planimetric) analysis accompanied by cathodoluminescence, SEM and XRD studies has been applied. The rocks are represented by conglomerates (mostly fine-grained and polymictic), sublithic, lithic and subarkosic quartz sandstones, mudstones and claystones. Their colours are variable and range from red-brown to light-grey-greenish. It is due to Eh and pH changes within the sediments during diagenetic alterations.
