Toward a standardization of cryostructure and cryogenic soil structure terminology for the field description of permafrost‐affected soils

Soil Science Society of America Journal, Volume 90, Issue 1, January/February 2026.
Abstract This paper establishes standardized terminology and field documentation protocols for cryostructures and cryogenic soil structures in permafrost‐affected soils and provides brief guidance on descriptions of ground ice morphology and ice volume estimates.

Crustal Structure Across the Okavango Rift, Botswana: The SEISORZ Wide‐Angle Seismic Experiment

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract The Okavango Rift Zone (ORZ) is an incipient continental rift in Botswana at the terminus of the Southwestern Branch of the East African Rift System. The lack of syn‐rift magmatism and tectonic processes overprinting pre‐rift structures provide an opportunity to investigate incipient‐stage rift processes and the role of pre‐existing structures

Pseudotachylyte Formation in Brittle–Ductile Transition of the Anning River Fault Zone: Implications for Seismic Processes

Applied Sciences
Pseudotachylytes and cataclasites record transient seismic slips within the brittle–ductile transition zone and ductile flow layers. Investigating the mechanisms of pseudotachylytes can provide the most direct geological evidence for revealing seismic ...

East Meets West: The Trace of the Mesoproterozoic Kibaran Event in the Mantle Lithosphere Beneath Eastern Tanzania

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract We present elemental geochemistry and multiple isotopic systematics (Re‐Os, Lu‐Hf, Sm‐Nd and Sr) for mantle peridotite xenoliths from Lashaine in northern Tanzania. We use the data to examine how the major Proterozoic tectono‐thermal events that affected the crust of the western Tanzanian craton are imprinted on the lithospheric mantle in the ...

A compilation of information and data on the Manson impact structure [PDF]

A problem for the impact hypothesis for the Cretaceous-Tertiary (K-T) mass extinction is the apparent absence of an identifiable impact site. The Manson Impact Structure is a candidate because it is the largest recognized in the U.S.; it is relatively ...

Field Studies of the Archean in Grand Canyon [PDF]

, 1933
The oldest rocks of Arizona which form the precipitous walls of the inner or granite gorge of the Grand Canyon have never received the intensive study that has been given to their counterparts over the great northeastern plains of Canada, in the ...

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

Journal 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.

Creating a Critical Zone: Feedbacks Between Bedrock Geology, Water Retention, and Vegetation on an Exposed Bedrock Surface, Panola Mountain, Georgia, USA

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 1, January 2026.
Abstract Most of Earth's present‐day terrestrial surface is covered by regolith—the layers of soil, saprolite, and weathered bedrock that together comprise the critical zone. Recent research has focused on understanding fluxes of minerals, water, and energy through the critical zone under steady state assumptions.
