Flow units classification for geostatisitical three-dimensional modeling of a non-marine sandstone reservoir: A case study from the Paleocene Funing Formation of the Gaoji Oilfield, east China

open access: yesOpen Geosciences, 2018
Flow units classification can be used in reservoir characterization. In addition, characterizing the reservoir interval into flow units is an effective way to simulate the reservoir.

First shark record (Chondrichthyes, Elasmobranchii) from the Paleogene of Spitsbergen, Svalbard [PDF]

open access: yesPolish Polar Research, 2019
This is a short report about the first Cenozoic shark fossil from Svalbard. The specimen derives from the late Paleocene greenish sandstone of the Grumantbyen Formation, which is exposed in Fossildalen on the western side of Colesbukta on Spitsbergen ...

The first fossil representative of the dragonfly family Synthemistidae

open access: yesActa Palaeontologica Polonica
Gallosynthemis bechlyi gen. et sp. nov., described from the Paleocene maar of Menat (Puy-de-Dôme, France) is the firstever fossil record of the dragonfly family Synthemistidae. It shows the main synapomorphies of the family, viz.

Cenozoic evolution of the eastern Black Sea: a test of depth-dependent stretching models [PDF]

open access: yes, 2008
Subsidence analysis of the eastern Black Sea basin suggests that the stratigraphy of this deep, extensional basin can be explained by a predominantly pure-shear stretching history.

Upper Cretaceous, K/T boundary, and Paleocene agglutinated foraminifers from Hole 959D (Côte d'Ivoire-Ghana Transform Margin) [PDF]

open access: yes, 1998
Upper Cretaceous agglutinated foraminifer assemblages from Hole 959D of Ocean Drilling Program (ODP) Leg 159, Côte d’Ivoire-Ghana Transform Margin, reflect the subsidence history and paleoceanography of the widening equatorial Atlantic gateway.

Deformation of continental crust along a transform boundary, Coast Mountains, British Columbia [PDF]

open access: yes, 2010
New structural, paleomagnetic, and apatite (U-Th)/He results from the continental margin inboard of the Queen Charlotte fault (~54°N) delineate patterns of brittle faulting linked to transform development since ~50 Ma.

Indicators of hot fluid migration in sedimentary basins: evidence from the UK Atlantic Margin [PDF]

open access: yes, 2003
Microthermometric, petrographic and isotopic methods have been used to detect evidence for hot fluid flow in Mesozoic and Tertiary sediments from the NW UK continental margin, West of Shetland. New data presented here show that temperatures are hotter by

Tracing the origins and evolution of nymphalid butterflies (Lepidoptera) in the Atlantic Forest

open access: yesEcography, EarlyView.
Understanding the relative roles of diversification and dispersal is key to explaining large‐scale biogeographical patterns. Although both processes are known to shape biodiversity, their relative contributions remain understudied for many organisms. Here, we examine how these processes have jointly contributed to the exceptional diversity and endemism

Sedimentology and Economic Significance of Hangu Formation, Northwest Pakistan

open access: yesInternational Journal of Economic and Environment Geology, 2020
The Hangu Formation (Paleocene) consists of sandstone, siltstone, carbonaceous shale, coal and laterite. It is well exposed in the Trans Indus Surghar range and the southern Hazara basin.
