APPLICATION OF CHEMOSTRATIGRAPHY AND RE-OS GEOCHRONOLOGY TO THE MAIKOP SERIES OF EASTERN AZERBAIJAN: CONSTRAINING KURA AND SOUTH CASPIAN BASIN EVOLUTION
In addition to geochemical analysis of samples, this study seeks to better constrain the geochronology of the Maikop Series strata. Re-Os geochronology, originally developed for the dating of ore bodies in metamorphic and igneous rocks, has recently been applied to organic-rich mudstones. Re and Os bind to preserved organic matter and remain stable in high temperatures and through the generation and migration of hydrocarbons. Re-Os abundances in sediments are controlled by the input of continental vs. marine sediments, and the relative abundances of Re-Os may vary from basin to basin depending on the degree of basin isolation and the influx of sediment. Therefore, in addition to providing geochronologic data, the abundances of Re-Os may be used to reconstruct depositional environments and further constrain stratigraphy of the Maikop Series.
