New Zealand Geological Timescale 2025

New 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 ...

Multi-scale modelling of gas flow in nanoscale pore space with fractures

Journal of Rock Mechanics and Geotechnical Engineering, 2020
In this work, a multi-scale pore network with fractures is developed against experimental data in a wide range of degrees of water saturation. The pore network is constructed based on the measured microstructure information at several length scales.

The early origin of Iguanodontia: new insights into the macroevolution, diversity and biogeography of the clade

Palaeontology, Volume 69, Issue 2, 2026.
Abstract Iguanodontia (Dinosauria, Ornithischia) is a speciose group of herbivorous dinosaurs that include the famous genus Iguanodon, one of foundational members of the clade Dinosauria. Despite their very long history of research, several aspects of their systematic relationships and their evolutionary history remain somewhat nebulous.

The Jurassic of North-East Greenland: Jurassic dinoflagellate cyst stratigraphy of Hold with Hope, North-East Greenland [PDF]

Geological Survey of Denmark and Greenland Bulletin, 2004
Dinoflagellate cysts of the Middle–Upper Jurassic succession on northern Hold with Hope have been studied in order to establish a biostratigraphic framework and to date the succession.

High-precision U-Pb ages in the early Tithonian to early Berriasian and implications for the numerical age of the Jurassic-Cretaceous boundary [PDF]

, 2019
The numerical age of the Jurassic-Cretaceous boundary has been controversial and difficult to determine. In this study, we present high-precision U-Pb geochronological data around the Jurassic-Cretaceous boundary in two distinct sections from different ...

Sediment‐stressed reefs over the past 420 Myr

The Depositional Record, Volume 12, Issue 1, February 2026.
In order to fully elucidate the relationship between siliciclastic sedimentation and reef development, there needs to be a significant step change in how we record ancient and recent reefs. Only through the collection of constrained quantitative data, we can progress beyond the largely conjectural associations postulated for many ancient reefal systems.

The systematics and paleobiogeographic significance of Sub-Boreal and Boreal ammonites (Aulacostephanidae and Cardioceratidae) from the Upper Jurassic of the Bohemian Massif

Geologica Carpathica, 2014
Upper Jurassic marine deposits are either rarely preserved due to erosion or buried under younger sediments in the Bohemian Massif. However, fossil assemblages from a few successions exposed in northern Bohemia and Saxony and preserved in museum ...

From Quarries to Urban Construction Sites: Middle‐Late Mesozoic Limestones in the Public Architecture of Roman Verona, Italy

Geoarchaeology, Volume 41, Issue 1, January/February 2026.
ABSTRACT Numerous buildings, monuments, and infrastructural works in Verona were constructed during the Roman period using stone, a material abundantly available from quarrying areas located relatively close to the city. Petrographic investigations conducted by Transmitted Polarized Light Optical Microscopy (TPL‐OM) and complemented by colorimetric ...
