Automatic Crater Classification Using a Deep‐Learning‐Based Pipeline
Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.Abstract Identifying and classifying impact craters on Mars is crucial for understanding the planet's geological history and surface evolution. Traditional crater classification relies on manual annotation methods, which are often limited by human biases and the difficulty of interpreting geomorphological features.

Sedimentology, Volume 73, Issue 6, Page 2353-2380, October 2026.ABSTRACT Microporous carbonate rocks typically record complex diagenetic histories driven by microbial activity and fluid interactions within multiple diagenetic environments. The relative roles of meteoric and burial diagenetic processes in pore evolution remain debated, particularly within Cretaceous carbonate systems of the Middle East, as does the ...

Limitotipes of Lower Sakmarian and Artinskian stages boundary in the Urals
Литосфера, 2015 The section Usolka and duplicating its section Dal’ny Tulkas (Bashkortostan) are proposed as the stratotypes of the Lower Sakmarian stage boundary and Lower Artinskian stage boundary of the International Stratigraphic scale.

Sedimentology, Volume 73, Issue 6, Page 2488-2518, October 2026.ABSTRACT Previous studies have documented genetic divergence within the last few million years between northern and southern populations of terrestrial plants and animals along the Baja California peninsula, with many studies hypothesising that the divergence is due to an ancient seaway that crossed the central peninsula and created a physical barrier ...

A Shallow‐Marine Ecosystem Before Initial Tibetan Plateau Uplift
Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract The uplift of the Tibetan Plateau profoundly influences global atmospheric circulation, sediment transport, and biodiversity, but its pre‐uplift marine paleoenvironment remains poorly understood. Here we report the first discovery of an in situ benthic fossil assemblage from the Puga area in central Tibet, which was deposited on a shallow ...

The Depositional Record, Volume 12, Issue 4, September 2026.Middle Triassic turbidites in the Youjiang Basin were chiefly derived from a Late Palaeozoic continental arc along the southeastern South China Block, as revealed by detrital zircon U–Pb geochronology and tourmaline geochemistry, supporting a tectonic model driven by Paleo‐Pacific subduction rather than Paleo‐Tethyan closure.

The Depositional Record, Volume 12, Issue 4, September 2026.Allostratigraphically defined mudstone packages show marked along‐strike thickness variation, interpreted to be related to shifting thrust activity in the orogen; loading cycles lasted about 750 kyr. Close to the orogen, the forebulge is mantled by shelly sandstone whereas far from the orogen, the forebulge is typified by organic‐rich mudstone ...
