Seismic Stratigraphy of Eocene–Recent Mixed Depositional Systems on the SE New Zealand Continental Margin, Great South Basin

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
The continental margin of SE New Zealand is strongly influenced by the Southland Current and associated water masses. This new seismic stratigraphic study of the margin has revealed a range of depositional mounds and erosional channels that document the close interaction of turbidity and bottom currents in shaping the margin from the Mid‐Eocene onward.

Seismogeological structure model of the Anabar-Olenek region

Georesursy
The velocity characteristics of the Upper Proterozoic-Phanerozoic sedimentary cover of the AnabarOlenek region were studied, in particular, the bimodal character of the distribution interval P-wave velocities was established.

Comparing the Last Interglacial (MIS 5e) with the present interglacial period (MIS 1) using a multidimensional functional diversity analysis: The marine molluscs from Santa Maria Island (Azores Archipelago, central Atlantic) as a case study

Journal of Quaternary Science, Volume 41, Issue 2, Page 333-360, February 2026.
ABSTRACT Marine fossil records hold outstanding importance for ecological, evolutionary and biogeographical studies. Santa Maria Island in the Azores Archipelago (central Atlantic) features a remarkable marine fossil record spanning from the Pliocene to recent times.

Study of distribution patterns of oil- and water-saturated reservoirs in a section of the Achimov Formation

Актуальные проблемы нефти и газа
Background. Achimov sediments of the north of Western Siberia have a complex geological structure, which together with extremely low filtration-capacity properties creates problems in understanding the spatial distribution of oil- and water-saturated ...

Seasonal Ice Cover Could Allow Liquid Lakes to Persist in a Cold Mars Paleoclimate

AGU Advances, Volume 7, Issue 1, February 2026.
Abstract Geomorphic and stratigraphic studies of Mars prove that extensive liquid water flowed and pooled on the surface early in Mars' history. Martian paleoclimate models, however, have difficulty simulating climate conditions warm enough to maintain liquid water on early Mars.

Reconstructing the Distribution of Turbiditic Gas Sandstones in the SW Pannonian Basin Using Machine Learning Methods

Geophysical Prospecting, Volume 74, Issue 2, February 2026.
ABSTRACT Seismic interpretation in geologically complex environments still remains a challenge due to limited resolution and ambiguous facies differentiation. In this article the 3D seismic data from the Gola field, south‐western Pannonian Basin, were interpreted using unsupervised self‐organizing maps (SOM) on unlabelled data.

Characterizing a complex buildup in the Pearl River Mouth Basin of the northern South China Sea: an interplay of carbonates and igneous rocks

Frontiers in Marine Science
Volcanic mounds and carbonate buildups share similar geometries, making their differentiation in seismic data a significant challenge. This challenge is further compounded in complex buildups composed of both multi-stage developed igneous rocks and ...

Upper Cretaceous Seismic Stratigraphy and Magma‐Enhanced Petroleum System of the Offshore Indus Basin

Basin Research, Volume 38, Issue 1, January–February 2026.
Seismic data reveals Cretaceous stratigraphy and hydrocarbon potential beneath volcanic rocks in Offshore Indus Basin, where magmatic intrusions enhanced source rock maturation and hydrocarbon generation by 8%–18% during favourable timing coinciding with Deccan volcanism.
