the petroleum potential of the seyahou (ordovician) and sarchahan (lower silurian) formations in northern bandar abbas has not been investigated sufficiently. these sediments crop out as thinly laminated shales and are about 100 meters thick. a number of thirty-five selected samples were subjected to rock-eval pyrolysis followed by transmitted, reflected and uv light microscopy together with cl...

Introduction: At least some meteoritic nano-diamonds are likely of presolar origin because of their association with anomalous Xe-HL and Te isotopic components indicative of a supernova (SN) origin [1,2]. But the abundance of Xe is such that only ~1 in 10 6 nano-diamonds contains a Xe atom, and the bulk 13 C/ 12 C composition of nano-diamond acid residues is chondritic (solar) [3]. Therefore, i...

Detailed organic petrography analysis were conducted on drill core and cutting samples from the Nahr Umr (Middle Albian), Burgan (Lower Albian) and Ratawi (Hauterivian) formations on the Soroosh and Nowrooz fields, NW part of the Iranian sector of the Persian Gulf. The thermal maturity of the Middle Albian Nahr Umr Formation appears to have reached the top of the oil window. The underlying Burg...

Environmental analysis of offshore shale members of Upper Pennsylvanian Midcontinent cyclothems was undertaken using a combination of high-resolution X-radiography, petrography, and geochemical analyses. A hierarchical sampling strategy permitted investigation of (1) broad stratigraphic and geographic patterns of compositional variation through analysis of three shale members (Hushpuckney, Star...

In this study, we propose a predictive model for maceral discrimination based on Raman spectroscopic analyses of dispersed organic matter. micro-spectroscopy was coupled with optical and Rock-Eval pyrolysis set seven samples collected from Mesozoic Cenozoic successions the Outer sector Carpathian fold thrust belt. Organic petrography evidence type II/III kerogen complex organofacies composed by...
