Systematic Approach for Carbonate and Volcanic Facies Classification Based on Textural and Structural Variations Observed in Brazilian Pre‐Salt Acoustic Image Logs

open access: yesJournal of Petroleum Geology, Volume 49, Issue 3, Page 869-906, July 2026.
ABSTRACT Facies characterization in carbonate reservoirs remains challenging due to their pronounced textural and structural heterogeneity. Variations in grain packing, cementation, and diagenetic overprints produce contrasting acoustic responses in borehole image logs, often limiting the reproducibility of facies interpretation.

The Addition of a 3D Balanced Steady‐State Free Precession Pulse Sequence Improves Magnetic Resonance Imaging Identification of Certain Canine Cranial Nerves

open access: yesVeterinary Radiology &Ultrasound, Volume 67, Issue 4, July 2026.
ABSTRACT In people, magnetic resonance imaging (MRI) with high‐resolution, high T2‐weighted (T2w) contrast‐balanced steady‐state free precession (b‐SSFP) pulse sequences and 3D fast spoiled gradient‐echo (FSPGR) pulse sequences can improve visualization of cranial nerves (CNs) and associated osseous foramina. This prospective, observational study aimed

Pahoehoe Breakouts and Lava-Substrate Interactions: Insights from Large-Scale Experimental Lava Flows

open access: yes, 2023
Basaltic lava flows are one of the most visible geologic processes on Earth. Gaining a thorough knowledge of basaltic lava flow behavior is imperative to understanding Earth’s formation processes and for the protection of humanity. Studies of basalt flow

Lithosphere‐Asthenosphere Interactions Across the Indo‐Burma Subduction Zone From Sp Receiver Functions

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The Cenozoic convergence between the Indian and Asian plates has driven large‐scale mantle convection that interacts with both plates. Understanding this convergence benefits from clear imaging of the lithosphere‐asthenosphere boundary (LAB).

LAVA FLOWS AT SAKURAJIMA VOLCANO (II)-NUMERICAL SIMULATION OF THE 1914 LAVA FLOWS ON THE WESTERN SIDE OF SAKURAJIMA-

open access: yes, 1985
The progress of the 1914 lava flows on the western side of Sakurajima Volcano was examinedin detail by analyzing the photographs taken during the eruption and then the extrusion rateof the lava was estimated.

Subterranean environments contribute to three‐quarters of classified ecosystem services

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1582-1605, June 2026.
ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

Broad Fungal Compatibility and Seed Size May Facilitate Invasiveness in Two Asian Terrestrial Orchids Spathoglottis plicata and Arundina graminifolia

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
Two Asian orchids, Arundina graminifolia and Spathoglottis plicata, are expanding into tropical regions worldwide, showing invasive behavior. In this study, we investigated the factors underlying their success. Both species—as all orchids—require fungal carbon to germinate, but S.

Rapid changes of the lava‐delta coastlines formed by the 2021 volcanic eruption on La Palma, Canary Islands

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.
A new coastline formed during the 2021 eruption of La Palma quickly eroded, becoming crenellated and with pocket beaches, then retreated more gradually as resistant interiors of the lava were exposed. In contrast, a second thicker lava delta changed more gradually, highlighting the importance of lithology to coastal erosion.
