Abstract

COPPER MINERALIZATION AT MONASTERZEC NEAR LESKO (Middle Carpathianas)In the geological structure of the Monasterzec region (Fig. 1), there take part: variegated shales and marls belonging to the Silesian and Subsilesian series, the Menilite beds and the Krosno beds. The lithological development of the variegated sediments is illustrated on Fig. 2. Amidst the, variegated shales and marls there locally occur thin sandstone intercalations.Under the microscope both shales and marls appear as rocks consisting of argillaceous and carbonate substances of irregular, at times laminated, structure. Their texture is pelitic, compact; in it may be seen thin veins of granular calcite; sometimes, too, remnants of an undeterminable fauna with calcareous shells. Quartz appears as pelite; larger grains are rare. For illustrating the mineral composition of both shales and marls, the authors prepared differential thermal curves (Fig. 3) picturing the illitic character of the argillaceous substance.
