On the mid-Atlantic Coastal Plain of the United States, Paleocene sands and silts are replaced during the Paleocene-Eocene Thermal Maximum (PETM) by the kaolinite-rich Marlboro Clay. The clay preserves abundant magnetite produced by magnetotactic bacteria and novel, presumptively eukaryotic, iron-biomineralizing microorganisms. Using ferromagnetic resonance spectroscopy and electron microscopy,...

Deep complex oil and gas reservoirs are the future directions of exploration. The exploration potential Paleocene deposits in Lufeng sag is enormous. However, due to greater burial depth accumulation conditions Paleocene, few large-scale have been discovered next strategy unclear. In this study, based on geological data Southern sag, a model hydrocarbon functional element control constructed us...

Abstract Plant megafossils from the Paleocene-Eocene Thermal Maximum (PETM) in Bighorn Basin, north-central Wyoming, USA, document a dramatic shift floral composition, whereas palynofloral change same sections has appeared to be more subtle. We investigated this discrepancy by quantifying pollen preservation and measuring stable carbon isotope composition of specific taxa. Pollen grains belongi...

Extreme global warmth and an abrupt negative carbon isotope excursion during the Paleocene–Eocene Thermal Maximum (PETM) have been attributed to a massive release of methane hydrate from sediments on the continental slope [G.R. Dickens, J.R. O'Neil, D.K. Rea, R.M. Owen, Dissociation of oceanic methane hydrate as a cause of the carbon isotope excursion at the end of the Paleocene, Paleoceanograp...

The specified systematic study of calcareous nannofossils was carried out on successions Shiranish and Aaliji Formations. Four Samples have taken from (Kh-4) well, between (2600-2630) m, Northern Iraq. Twenty-five species were identified. According to the identified taxa, two biostratigraphic biozones determined, oldest youngest: 
 1- Rienhardtites lives Interval Biozone (CC24) Part. 2- Fa...
