Reservoir Potential Evaluation of the Middle Paleocene Lockhart Limestone of the Kohat Basin, Pakistan: Petrophysical Analyses

open access: yesInternational Journal of Economic and Environment Geology, 2020
The Lockhart Limestone is evaluated for its reservoir potential by utilizing wireline logs of Shakardara-01 well from Kohat Basin, Pakistan. The analyses showed 28.03% average volume of shale (Vsh), 25.57% average neutron porosity (NPHI), 3.31% average ...

Saheb Granitoid Batholith, North of Kurdistan: An Evidence of Cretaceous- Paleocene Magmatism in the Sanandaj-Sirjan Zone

open access: yesJournal of Economic Geology, 2020
Introduction The Iranian plateau is part of the Alpine-Himalayan orogenic belt, which consists of several continental fragments separated from each other by major boundary faults and/or ophiolitic suture zones (Gansser, 1981).

Could changing ocean circulation have destabilized methane hydrate at the Paleocene/Eocene boundary? [PDF]

open access: yes, 2002
During the Paleocene-Eocene Thermal Maximum (PETM, ~55 Ma), marine and terrestrial carbon isotope values exhibit a negative shift of at least 2.5‰, indicative of massive destabilization of marine methane hydrates, releasing ~1100 gigatonnes of methane ...

Spatial Patterns of Chemical Weathering at the Basal Tertiary Nonconformity in California from Multispectral and Hyperspectral Optical Remote Sensing

open access: yesRemote Sensing, 2019
Visible through shortwave (VSWIR) spectral reflectance of the geologic units across the basal Tertiary nonconformity (BTN) is characterized at three spatially disparate locations in California. At two of these sites, location-specific spectral endmembers

Scaled biotic disruption during early Eocene global warming events [PDF]

open access: yes, 2012
Late Paleocene and early Eocene hyperthermals are transient warming events associated with massive perturbations of the global carbon cycle, and are considered partial analogues for current anthropogenic climate change.

Modeling the climate response to a massive methane release from gas hydrates [PDF]

open access: yes, 2004
[1] The climate response to a massive release of methane from gas hydrates is simulated in two 2500-year-long numerical experiments performed with a three-dimensional, global coupled atmosphere-sea ice-ocean model of intermediate complexity.
