Late Viséan (Mississippian) ammonoids (Cephalopoda) from the Central Moroccan Meseta

European Journal of Taxonomy
Late Viséan (Mississippian) ammonoids (Cephalopoda) from the Central Moroccan Meseta are described monographically for the first time. Several localities have yielded low-diversity assemblages, consisting mainly of species already known from southern ...

Multi‐proxy sequence stratigraphy of a mixed carbonate–siliciclastic shelf across the Jurassic–Cretaceous transition

The Depositional Record, Volume 12, Issue 4, September 2026.
An integrated facies, MS and XRF‐based approach applied to the Tithonian–Berriasian Sidi Khalif Formation (central Tunisia) resolves five Tithonian and eight Berriasian third‐order sequences, showing how mixed carbonate–siliciclastic shelves record coupled eustatic, climatic and tectonic controls and providing a transferable template for similar mud ...

Contrasting Dispersal Histories Shape Distinct Evolutionary Trajectories Between Malesian and Pantropical Talipariti (Malvaceae)

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Talipariti (Malvaceae) comprises two lineages with contrasting geographic ranges across Malesia: a pantropical sea hibiscus group and a Papuan group restricted to New Guinea and adjacent islands. Using phylogenomics, divergence‐time estimation, and quantitative biogeographical modelling applied to herbarium‐derived genomic data, we demonstrate that the

MULTI-ARCHIVE TEMPERATURE RECONSTRUCTION OF THE RUSSIAN ARCTIC FOR THE PAST TWO MILLENNIA

Geography, Environment, Sustainability, 2014
We present a multi-archival mean annual quantitative temperature reconstruction for Northeastern Europe covering the period of the past two millennia based on tree-ring, pollen, and historical data. This reconstruction was developed primarily to build up

High‐frequency sequences within a retrogradational deltaic succession: Upper Cenomanian Dunvegan Formation, Western Canada Foreland Basin

The Depositional Record, 2020
After prograding for several hundred kilometres during Middle Cenomanian time, the Dunvegan delta complex in north‐west Alberta and adjacent British Columbia experienced stepwise transgression, commencing at about the Middle to Late Cenomanian boundary ...

Introduction: Advances in Palaeogeography [PDF]

Geological Magazine, 2019
This special issue of Geological Magazine is dedicated to the memory of Dr Alan Gilbert Smith, Fellow of St John's College and Emeritus Reader in Geology at the University of Cambridge, who passed away on 13 August 2017 at the age of 80. I first met Alan at the 5th International Symposium on Eastern Mediterranean Geology in Thessaloniki, Greece, in ...

Exhumed eo‐Alpine High‐Pressure Rocks Fed Campanian Turbidites in Eastern Sardinia

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract This study investigates the detrital record of the early orogenic evolution of the Sardinia‐Calabria system, preserved in Upper Cretaceous arenites exposed in eastern Sardinia. Sardinia and Corsica form a continental block that includes a segment of the Alpine orogen and of its former foreland basin.

Oxygen Isotopic Composition of Miocene Meteoric Water (δ18Ow) in Alpine Foreland Basins

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract The reconstructed stable oxygen isotopic composition of meteoric water (δ18Ow) is widely used for paleoclimate reconstructions. Understanding past environmental factors that drove changes in δ18Ow is essential for interpreting past climate conditions.

Change in South Asian Summer Monsoon During MIS7, an Interglacial Complex of the Middle Pleistocene With High Obliquity Forcing

Paleoceanography and Paleoclimatology, Volume 41, Issue 8, August 2026.
Abstract The South Asian summer monsoon is a major component of the global climate system, yet its response to varying boundary conditions remains debated. We present pollen data from IODP Site U1446 (Bay of Bengal), recording vegetation changes in India's Core Monsoon Zone (CMZ) between 260 and 190 ka, spanning Marine Isotopic Stage (MIS) 7.

Thermal and Structural Reconstruction of an Eroded Foreland Basin: Central Appalachian Basin, USA

Basin Research, Volume 38, Issue 4, July–August 2026.
New low‐temperature thermochronology and modelling reveal a complex thermal history for the central Appalachian Basin. Results indicate Carboniferous exhumation of the fold‐thrust belt and Mesozoic heating in the foredeep linked to the Rome Trough. Deeply buried Devonian source rocks were consequently pushed past the peak oil and gas windows.
