Seismic interpretation and sequence stratigraphic analysis of the Bahariya Formation in the South Umbaraka oilfields (Western Desert, Egypt): insights into reservoir distribution, architecture, and evaluation

open access: yesGeomechanics and Geophysics for Geo-Energy and Geo-Resources, 2023
The integration of multiscale datasets, including seismic, well-logs and stratigraphy, is providing a precise picture about reservoir evaluation and spatial distribution.

Sequence stratigraphy in Proterozoic successions

open access: yesGeology, 1988
Sedimentological logging and facies mapping have been used to identify depositional sequences bounded by subtle but regionally persistent unconformities in rocks of Proterozoic age in the western United States, South Australia, and northwestern Canada. We conclude from these studies that the sequence stratigraphic approach is of considerable importance

Mississippian (Early Carboniferous) sequence stratigraphy of the Rhenish Kulm Basin, Germany

open access: yes, 2016
1. IntroductionThe relation between sea-level variations and sedimentary sequences that are bound by erosional unconformities was already elucidated by Sloss et al. (1949) and Sloss (1963) concerning the cratonic sequences of the conterminous U.S.

Quantitative X‐Ray Fluorescence Imaging to Evaluate the Efficacy of Micro‐Structured Cellulose Foams and Poultices in Wall Painting Desalination

open access: yesChemistry–Methods, EarlyView.
This work assesses, through a quantitative micro energy dispersive X‐ray fluorescence imaging, the effective use of micro‐structured cellulose foams as a sustainable alternative to traditional poultices for desalinating fresco paintings. Foams were between 6 and 10 times more efficient, achieving rapid and in‐depth salt removal with reusability and ...

Revision of the age and stratigraphic relationships of Hinemaiaia Tephra and Whakatane Ash, North Island, New Zealand, using distal occurrences in organic deposits [PDF]

open access: yes, 1986
The stratigraphic and chronologic relationships of Hinemaiaia Tephra and Whakatane Ash are examined using distal tephras preserved in organic-rich deposits at five sites in eastern and northern North Island, New Zealand. A c.

Wetlands as environments of early human occupation: A new classification for freshwater palaeowetlands

open access: yesThe Depositional Record, EarlyView.
A new classification for inland freshwater palaeowetlands to be used in the field or core laboratory by sedimentologists, providing examples from the Guadix Basin (southern Spain). Abstract Present wetlands have proven to be delicate, biodiverse ecosystems, that are natural sinks for CO2 and act as good indicators for climate changes.

Sequence stratigraphy and uranium mineralization model of uranium-bearing rock series in the southern margin of Erlian Basin

open access: yes矿业科学学报, 2018
Based on drilling data, seismic sections and sample test results, the theory of continental to sequence stratigraphy was applied to investigate uranium accumulation of the Early Cretaceous uranium-bearing rock series in the southern margin of Erlian ...

Ages on weathered Plio-Pleistocene tephra sequences, western North Island, New Zealand [PDF]

open access: yes, 2001
Using the zircon fission-track method, we have obtained five ages on members of two strongly-weathered silicic, Pliocene-Pleistocene tephra sequences, the Kauroa and Hamilton Ash formations, in western North Island, New Zealand.

Stratigraphy of Tithonian (Ohauan-Puaroan ) marine beds near Port Waikato, New Zealand, and a redescription of Belemnopsis aucklandica (Hochstetter). [PDF]

open access: yes, 2001
Some 1500 m of marine Ohauan and Puaroan strata in the Port Waikato region of New Zealand are restudied in an attempt to resolve lithostratigraphic and biostratigraphic anomalies in published works.
