Shifting the Paradigm: Redefining the Chronostratigraphy of the Triassic Rewan Group, Bowen Basin, Australia

Basin Research, Volume 38, Issue 3, May–June 2026.
New U–Pb zircon dating shows the Rewan Group was deposited between ~250 and 233 million years ago and that sedimentation shifted across the basin through time, with earlier deposition in the foredeep and later deposition in the back bulge. Testing multiple dating approaches and grain‐selection strategies improves confidence in these age estimates and ...

Diagenetic Heterogeneity of Deep Sandstones and Its Relationship to Oil Emplacement: A Case Study from the Middle Jurassic Toutunhe Formation in the Fukang Sag, Central Junggar Basin (NW China)

Geofluids, Volume 2017, Issue 1, 2017., 2017
The Middle Jurassic Toutunhe Formation at depths of approximately 4000–6000 m has increasingly come into focus as a current deep reservoir target in the central Junggar Basin (NW China). Based on petrography, SEM, stable isotopes, and fluid inclusion analyses, the goals of this study were to investigate the effect of depositional lithofacies on ...

Microfacies analysis, sedimentary environment and sequence stratigraphy of the Ilam Formation (Coniacian? - Santonian) in the northwestern part of the Abadan Plain [PDF]

Journal of Stratigraphy and Sedimentology Researches, 2020
The Ilam Formation (Coniacian? –Santonian), is among the most important oil reservoirs of the Abadan Plain, SW Iran. Despite its reservoir significance, there is no comprehensive knowledge about the geological characteristics and factors controlling ...

Late Triassic Hydroclimatic Changes in Central China Linked to Evolving Mountain Topography

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract During the Late Triassic, tropical Pangea drifted northward into subtropical latitudes and became progressively drier. In contrast, South China, despite experiencing a similar latitudinal shift, transitioned from an arid to humid climate. Based on the sedimentary record of the Zigui Basin, this study constrains the arid to humid climatic shift

Tectonics, geology and origins of Te Riu‐a‐Māui / Zealandia

New Zealand Journal of Geology and Geophysics, Volume 68, Issue 4, Page 531-567, December 2025.
ABSTRACT Te Riu‐a‐Māui / Zealandia is a 95% submerged, five million square km southern hemisphere continent that includes the islands of New Zealand and New Caledonia. For the last 45 million years (Ma) Zealandia has been cut by the Pacific‐Australian plate boundary which today changes character from a west‐dipping subduction zone in the north to ...

High‐level stratigraphic scheme for New Zealand rocks

New Zealand Journal of Geology and Geophysics, Volume 57, Issue 4, Page 402-419, December 2014., 2014
We formally introduce 14 new high‐level stratigraphic names to augment existing names and to hierarchically organise all of New Zealand's onland and offshore Cambrian–Holocene rocks and unconsolidated deposits. The two highest‐level units are Austral Superprovince (new) and Zealandia Megasequence (new).

Microfacies, depositional environment, sequence stratigraphy and diagenetic process affected the Doroud Formation in the Eram Section (south Neka), north flank of central Alborz [PDF]

Journal of Stratigraphy and Sedimentology Researches, 2020
The Permian deposits (Doroud Formation) are exposed in a wide area of central Alborz. A stratigraphic section of Permian deposits in the Eram section (South Neka) has been selected for the study of facies, depositional environments, sequence stratigraphy,
