A~tract--The Cretaceous/Tertiary (K/T) boundary is marked by extensive changes in the sedimentary fossil record of continental and marine life. Organic matter in sediments from above and below the K/T boundary has been studied to identify consequences of the biotic extinctions and of the changes in biological productivity which occurred at this time. Data from locations encompassing a variety o...

Tarim Basin is the largest Petroliferous basin in China, while its shale gas development potential has not been fully revealed. The organic-rich black middle Ordovician Heituao Formation from Tadong low uplift of considered as an important source rock and characteristic large thickness, high organic matter content thermal maturity degree. To obtain potential, geochemical, mineralogical mechanic...

The exploration well ANH-CR-Montecarlo-1X, in the southern part of Cesar-Ranchería basin Colombia, cuts sedimentary rocks assigned to Cogollo Group (Barremian-Cenomanian). present study integrates petrographic techniques (thin section microscopy and scanning electron microscopy), geochemistry (total organic carbon pyrolysis rock-eval) basic petrophysics establish thermal maturity potential thes...

The Taranaki Basin in New Zealand presents the most promising territory for strategies of hydrocarbon exploration and development. This basin contains multiple source rock levels its sedimentary successions formed during syn- post-rift periods. deepest rocks, found Rakopi Formation, were deposited deltaic to deep marine environments consist gas-prone coal organic-rich mudstone lithofacies. Howe...

Contrasting tillage strategies not only affect the stability and formation of soil aggregates but also modify concentration thermostability organic matter associated with aggregates. Understanding carbon retention ability under different systems is essential to ascertain potential terrestrial storage. We characterized (SOC) within various aggregate size classes both zero conventional using nove...

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...

Abstract The present study aims to investigate the origin, type, thermal maturity and hydrocarbon generation potential of organic matter paleo-depositional environment Early Paleocene (Danian) Hangu Formation outcropped in Kala-Chitta Range Northwest Pakistan, Eastern Tethys. Organic-rich shale coal intervals were utilized for geochemical analyses including TOC (total carbon) Rock–Eval pyrolysi...
