Testing the fidelity of zircon as a provenance indicator in fluvial‐fan successions: An example from the Palaeogene Colton Formation, Central Utah, USA

The Depositional Record, Volume 11, Issue 2, Page 511-536, April 2025.
This study integrates and expands the U–Pb detrital zircon dataset from the Colton fluvial system to highlight spatial variations in provenance signals within the early Palaeogene infill of the south‐western Uinta Basin, in Utah. The provenance data sheds light on the origin of clastic sediment and on the relationship with potential palaeodrainage ...

Comparison of Tidalites in Siliciclastic, Carbonate, and Mixed Siliciclastic‐Carbonate Systems: Examples from Cambrian and Devonian Deposits of East‐Central Iran

International Scholarly Research Notices, Volume 2013, Issue 1, 2013., 2013
For the comparison of lithofacies in siliciclastic, carbonate, and mixed siliciclastic‐carbonate tidal systems, three successions including Top Quartzite (Lower‐Middle Cambrian), Deranjal Formation (Upper Cambrian), and Padeha Formation (Lower‐Middle Devonian) in the north of Kerman and Tabas regions (SE and E central Iran) were selected and described,

Sedimentology and reservoir characterisation of Lower Jurassic clastic sedimentary rocks, Salt and Trans Indus Ranges, Pakistan: Evidence from petrography, scanning electron microscopy and petrophysics

The Depositional Record, Volume 11, Issue 2, Page 698-717, April 2025.
In this study, sandstones of the Lower Jurassic Datta Formation (DF‐LJ) in the Salt and Trans‐Indus Ranges are investigated regarding composition, diagenesis, provenance and reservoir properties using petrography, scanning electron microscopy (SEM) and petrophysical analysis.

A tectonic reconstruction model for Aotearoa‐New Zealand from the mid‐Late Cretaceous to the present day

New Zealand Journal of Geology and Geophysics, Volume 67, Issue 4, Page 527-550, December 2024.
ABSTRACT We present a mid‐Late Cretaceous to present day tectonic reconstruction model for Aotearoa‐New Zealand. Our GPlates model comprises 50 rigid crustal blocks grouped into regions with common deformation histories set within a well‐defined Australia‐Pacific‐Antarctica plate circuit tied to a published global paleomagnetic absolute reference frame.

Sediment Provenance Along the Middle Miocene‐Pleistocene Nankai Subduction Zone From Sediment Transport to Accretion: Implications for Stratigraphy in the Accretionary Prism

Geochemistry, Geophysics, Geosystems, Volume 25, Issue 8, August 2024.
Abstract Based on U‐Pb dating of zircon crystals and petrographic analysis, this study provides new insights into the paleogeographic and accretion evolution along SW Japan. Our data are consistent with an older submarine fan identified from drilling in the Shikoku Basin (Kyushu Fan ∼14.7–12.2 Ma), having a mixed sand provenance from the paleo‐Yangtze ...

Petrofacies Analysis—A Petrophysical Tool for Geologic/Engineering Reservoir Characterization

, 1999
Abstract Petrofacies analysis is defined as the characterization and classification of pore types and fluid saturations as revealed by petrophysical measurements of a reservoir. The word “petrofacies” makes an explicit link between petroleum engineers' concerns with pore characteristics as arbiters of production performance and the ...

Detection of flow units of Quseir Formation (Lower Campanian) as a potential reservoir using experimental correlations of capillary pressure derived parameters, Gebel el-Silsila, Egypt

Journal of Petroleum Exploration and Production Technology, 2020
Sandstone surface samples were collected from Quseir Fm., a member of Nubian Sandstone at Gebel el-Silsila and subjected to petrographical investigation using polarizing microscope. X-Ray diffraction was carried out to determine mineralogy.

Porosity evolution and geometry in Santos Basin Aptian presalt petrofacies

AAPG Bulletin
ABSTRACT The presalt deposits from offshore southeastern Brazil account for approximately 3/4 of the total hydrocarbon production of the country. Consequently, they are the subject of various studies aimed at better understanding the primary and diagenetic controls on their reservoir quality.
