A Fluvio‐Lacustrine Environment Preserved in the Jezero Crater Inlet Channel, Neretva Vallis, Mars

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Martian fluvial valleys provide evidence for the surface flow of liquid water, making them a key target for rover‐based investigations of ancient habitability. The Mars 2020 Perseverance rover spent ∼85 sols exploring the Bright Angel formation, exposed across the floor of Neretva Vallis: the western inlet channel of Jezero crater.

Tourmaline records the hydrothermal events related to Zn-Pb mineralization around the Murguía diapir (Basque Cantabrian Basin, N Spain)

open access: yesGeologica Acta, 2019
The chemical composition of tourmaline has been used as a host environment register as well as a potential exploration tool for mineral deposits. In this study, the textural and chemical composition of tourmalines associated with Zn-Pb mineralizations ...

The Gravity Signature of a Large Quaternary Depocentre off Southeastern Canada [PDF]

open access: yes, 1992
New bathymetry, gravity and Pliocene - Quaternary sediment isopach maps have been compiled and gridded for the Scotian margin. A large positive gravity anomaly exists over the Laurentian Fan, which is the major Pliocene - Quaternary depocentre on the ...

Anatomy of Rift‐Segmenting Transfer Zones: New Insights From the 3D Integrated Interpretation of the Southeastern Sector of the Basque‐Cantabrian Basin and the Pamplona Fault (Pyrenees, N Spain)

open access: yesBasin Research, Volume 38, Issue 1, January–February 2026.
An updated view of the southern part of the Cantabrian‐Pyrenean junction through a 3D geological model shows the first conclusive evidence for the ~65 km‐wide diffuse Pamplona transfer zone linking the Basque‐Cantabrian and Mauleon segments of the Pyrenean rift. This transfer zone also affected the style of deformation and configuration of the Pyrenean

The impact of diapirism on geothermal reservoir properties of the Estopanyà and Boix synclines (South-Central Pyrenees)

open access: yesGeothermal Energy
This study investigates petrological and thermophysical properties of rocks from the Estopanyà and Boix synclines (salt basins) to evaluate their potential as analogues for geothermal reservoir.

Submarine Salt Karst Terrains [PDF]

open access: yes, 2016
Karst terrains that develop in bodies of rock salt (taken as mainly of halite, NaCl) are special not only for developing in one of the most soluble of all rocks, but also for developing in one of the weakest rocks.

Radar Polarimetry in Glaciology: Theory, Measurement Techniques, and Scientific Applications for Investigating the Anisotropy of Ice Masses

open access: yesReviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract Dielectric anisotropy in ice alters the propagation of polarized radio waves, so polarimetric radar sounding can be used to survey anisotropic properties of ice masses. Ice anisotropy is either intrinsic, associated with ice‐crystal orientation fabric (COF), or extrinsic, associated with material heterogeneity, such as bubbles, fractures, and ...

Geology of the Central High Atlas diapiric province (Rich-Imilchil): a cartographic synthesis

open access: yesJournal of Maps
We present a geological map of the Central High Atlas of Morocco (excluding the mountain fronts), illustrating a structure consisting of narrow ridges of lower Jurassic carbonates, occasionally cored by Triassic Keuper rocks and basalt, or by mid-late ...

Salt and the Development of Human Settlements with Balnear and Climateric Potential within the Romanian Intra-Carpathian Space

open access: yesPresent Environment and Sustainable Development, 2019
Deposit salt in Romania has extremely important reserves, considered even inexhaustible at the current exploitation level. The biggest salt resources are found in the intra-Carpathian arch, represented by Transylvania and Maramures.
