LITHOLOGICAL AND GEOCHEMICAL FEATURES OF TURONIAN CARBONATES WITH STYLOLITES IN POKUTTYA–BUKOVYNA (UKRAINIAN CARPATHIANS)
Journal Title: Biuletyn Państwowego Instytutu Geologicznego - Year 2012, Vol 449, Issue 449
Abstract
Chemical analysis of carbonates with stylolites from the autochthon of the Pokuttya–Bukovyna Carpathians showed that the СаСО3 content in the rocks ranges between 68 and 92%, insoluble residue makes 8–32%. Investigation of clayey limestones using the polarizing microscopy allowed to establish that the 0.02–1 mm sized organic debris (foraminifera, gastropods, brachiopods and inocerams) makes 40–55% of the rock. The rest is the matrix represented by pelitomorphic calcite. X-ray diffractometry showed that insoluble residue of the organic-rich clay from stylolites is represented by the hydromicaceous mineral – illite with admixture of organic matter. Results of quantitative spectral analysis revealed the increased iron and strontium (>10 times) content in both limestones and organic-rich clays. Infrared spectrometry of chloroform bitumen extracted from the organic-rich clay from stylolites showed that the dispersed organic matter by its origin consists mainly of planktonogenic (autochthonous) microcomponents and underwent significant postsedimentary transformations: polymerization and oxidation.
