AUTHIGENIC FELDSPARS IN CARBONATE ROCKS OF THE WESTERN CARPATHIANS

Year, pages: 1994, 103 - 111

Authigenic albites with frequent intergrowths of Roc Tourne and orthoclases are present in many horizons of Permian, Mesozoic and occasionally also in Paleocene limestones. They are formed in lithified rocks tens of millions of years after deposition, by the destruction of clay minerals and clastic feldspars. Solutions proceeding from evaporites have a favourable influence. The formation of authigenic feldspars in clasts of conglomerates was proved. Tracing the frequency of authigenic feldspars in thin sections of approximately equal outcropping rocks in different tectonic units gave the possibility to compare the degree to which they have been affected by heat and pressure (the pre-metamorphic stage and initial anchimetamorphosis).
