Investigation of Horst-Graben Structures around Gülşehir (Nevşehir-Central Anatolia) with PSInSAR and Lidar

Black Sea Journal of Engineering and Science
This study examined horst-graben structures in the study area using the Interferometric Synthetic Aperture Radar (PSInSAR) method, and the movements in the line of sight (LOS) were determined. Both field and PSInSAR and Lidar studies were evaluated together.

Evolving late Triassic–Jurassic environments of western Europe: the Schwäbisch Gmünd geological path in southwest Germany compared to the ‘Jurassic Coast’ of Dorset, southern England

Geology Today, Volume 42, Issue 3, Page 134-146, May/June 2026.
The geology of southwest Germany is dominated by continental to marine sedimentary rocks deposited within Mesozoic sedimentary basins which have yielded economic hydrocarbon deposits. This stratigraphy has formed the focus of geological and stratigraphical research for centuries, with world‐famous exposures becoming type sections and lending their name

Comparative Analysis of Seismicity Across Three Depth‐Dependent Slip Regimes in the Japan Trench Subduction Zone

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Understanding the cause of spatial variations in seismicity is crucial for comprehending the physics governing earthquake activity. Off Iwate, in the northern Japan Trench subduction zone, the plate boundary can be divided into three distinct zones based on depth‐dependent slip regimes: the slow earthquake, asperity, and stable creeping zones.

Optimal mud pressure design using nonlinear failure criteria for wellbores in shaley sedimentary reservoir

Deep Underground Science and Engineering, Volume 5, Issue 1, Page 144-159, March 2026.
The present study uses the Modified Mohr‐Coulomb true‐triaxial failure criterion (MMC_TT), which predicts the strength of rock better than the MGC criterion in laboratory true‐triaxial tests to overcome the limitations. Moreover, based on the data from previously published five vertical wells in the Krishna‐Godavari basin (K‐G basin), an empirical ...

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.
