Petrophysics from the air to improve understanding of rock properties in the UK [PDF]

open access: yes, 2013
Electromagnetic geophysical applications exploit a petrophysical relationship governing the electrical properties of rocks. Given the extensive nature of many airborne electromagnetic surveys it seems natural to classify, and hence simplify, the ...

Geochemical Disequilibrium at the Brittle‐Ductile Transition

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.
Abstract We investigate the microtextural, microchemical, and isotopic effects of late‐stage ductile deformation in quartzite mylonites and kyanite–muscovite–quartz veins from the Raft River shear zone (Utah). Quartz microstructures record pervasive disequilibrium, expressed by unannealed features including undulatory extinction, deformation lamellae ...

Geology of the Transverse Range Province, Southern California [PDF]

open access: yes, 1954
The Transverse Range province of southern California is an elongate geomorphic and structural unit that trends essentially east-west across parts of Santa Barbara, Ventura, Los Angeles, San Bernardino, and Riverside Counties (pl. 4).

Effects of Oscillating Pore Pressure of Fluid Injection on Fault Slip Described by Rate and State Friction

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Injection of pore fluid can substantially affect fault slip, often resulting in seismic activity. We simulate the axisymmetric compression experiments of Noël, Passelégue, et al. (2019), https://doi.org/10.1029/2019jb018517 on a saw‐cut specimen of Fontainebleau sandstone subjected to periodic oscillations of fluid pore pressure.

Were There Tides on Ancient Mars?

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract Tides are a key component in the Earth system as they help regulate climate and sustain life. Mars very likely had a surface ocean around 4–3 billion years ago. The NASA Curiosity Rover and the CNSA Zhurong Rover were sent to Gale Crater and the Vastitas Borealis Formation (VBF) on Mars to explore the surface and search for evidence of the ...

Logging evaluation method of fracturability of tight sandstone reservoirs

open access: yesYouqi dizhi yu caishoulu
The fracturability of reservoirs is an essential parameter for selecting perforation stages and predicting hydraulic fracturing effects, but fracturability evaluation for tight sandstone reservoirs lacks unified methods and standards. This paper studies Chang 6 tight sandstone reservoir in an oilfield in the southeastern part of Ordos Basin and ...

No Groundwater, No Fish: The Critical Role of Groundwater in Supporting Non‐Glacial, Salmon‐Bearing Rivers in South‐Central Alaska

open access: yesJAWRA Journal of the American Water Resources Association, Volume 62, Issue 2, April 2026.
ABSTRACT Groundwater discharge plays an important role in the hydrologic and ecologic functioning of rivers including sustaining streamflow and related habitat year‐round. Simultaneously, groundwater supports the increasing demands of people as the global population continues to grow.
