Development and Application of a Simplified Method for Preliminary Assessment of Enhanced Oil Recovery and CO2 Geological Storage in Petroleum Reservoirs

open access: yesGreenhouse Gases: Science and Technology, Volume 16, Issue 2, Page 238-252, April 2026.
ABSTRACT Geologic carbon storage in depleted oil and gas reservoirs is a key CO2 mitigation strategy, utilizing existing infrastructure such as injection wells and pipelines, while capitalizing on well‐characterized subsurface properties. This article introduces a versatile methodology designed to estimate critical parameters, including the number of ...

Polycyclic Metamorphism, Exhumation, and Recycling of Subduction Complex Rocks, Cedros Island, Baja California

open access: yesTectonics, Volume 45, Issue 4, April 2026.
Abstract High‐pressure rocks from subduction complexes are key records of the physical and chemical processes that operate on the subduction interface, but interpretation of these records requires accurate structural understanding of where they formed in the subduction zone and the mechanisms by which they were exhumed. We present new geologic mapping,

Biostratigraphy and microfacies of the pelagic carbonate formations in the Yavorets section (Tithonian–Berriasian), Western Balkan Mts, Bulgaria

open access: yes, 2019
Calpionellid study has provided new evidence of early and late Tithonian age of the top of the Gintsi Formation, and of late Tithonian and early Berriasian age of the Glozhene Formation in the Yavorets section (Western Balkan Mts, Bulgaria).

A new spiny lobster from the Upper Jurassic Štramberk-type limestones of Inwałd, Andrychów Klippen, southern Poland

open access: yesBSGF - Earth Sciences Bulletin, 2017
A new palinurid, Palaeopalinurus czarnieckii, is recorded from Upper Tithonian Štramberk-type limestones at Inwałd, southern Poland. The specimen shows better preservation anteriorly than available specimens of the type species of the genus.

Systematic revision and evolution of the Tithonian family Chitinoidellidae Trejo, 1975

open access: yesCarnets de géologie (Notebooks on geology), 2021
Several new genera and species of the family Chitinoidellidae Trejo, 1975, were erected by Pop (1997, 1998a, 1998b). Some of these taxa are justified, but others are inadequately defined, and require revision. I discuss herein the non-validity of some taxa and propose a new systematic classification and an evolutionary framework for the family ...

Depositional Facies, Sequence Stratigraphy, and Diagenesis of Lower Cretaceous Carbonate Reservoir, Southern Iraq: Implications for Petroleum Exploration

open access: yesJournal of Petroleum Geology, Volume 49, Issue 2, Page 312-345, April 2026.
ABSTRACT The Lower Cretaceous Yamama Formation of southern Iraq represents a key carbonate reservoir within Iraq and the Middle East, yet its complex depositional facies architecture and diagenetic alterations present challenges for predicting reservoir quality.

Early Tithonian (Late Jurassic) ammonite Parapallasiceras newly discovered from the Itoshiro Subgroup (Tetori Group) in the Hida Belt, northern Central Japan

open access: yes, 2005
Early Tithonian (Late Jurassic) ammonite Parapallasiceras cf. pseudocontiguum (Donze and Enay) was discovered in situ from the Kamihambara Formation of the Itoshiro Subgroup (Tetori Group) distributed in the Hida Belt, in Fukui Prefecture, northern ...

A new thalattosuchian crocodyliform from the Tithonian (Upper Jurassic) of northeastern Mexico

open access: yesComptes Rendus Palevol, 2006
Recent fieldwork in the Early Tithonian of northeastern Mexico has yielded the partial cranium and associated fragmentary postcranial elements of a thalattosuchian. The specimen is described and referred to a new species of the genus Geosaurus characterised by elongated, narrow, oval supratemporal fenestrae, and a prefrontal that excludes the frontal ...

New Zealand Geological Timescale 2025

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
New Zealand Geological Timescale 2025 (NZGT 2025) is the first comprehensive update and revision of the New Zealand Geological Timescale in a decade. The criteria used to establish age ranges of New Zealand Stages within the NZGT have been reviewed, calibrated, and revised where required against the 2023/04 International Chronostratigraphic Chart and ...
