Tracing methane sources in shallow waters of the North Sea: Biogenic signatures and hydrocarbon transport near abandoned wells

Limnology and Oceanography, Volume 71, Issue 7, July 2026.
Abstract Numerous abandoned wells in the North Sea may provide gas, particularly methane (CH4), migration pathways by penetrating shallow, biogenic gas accumulations. However, related sampling campaigns have been largely contradictory and lack a substantial database. Research cruise MSM98 targeted the abandoned wells B18‐1, DOK 1‐X, B11‐2, THOR and D‐1

Post‐Miocene Transtensional Opening of the Northern Red Sea

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract The mechanism of opening, as well as the crustal characteristics of the northern Red Sea are subject of ongoing controversial scientific debate. With the objective of elucidating the nature of rifting in this area, a grid of 2D multi‐channel reflection seismic data was acquired off the Al Wajh carbonate platform (AWCP), and supplemented by ...

Probabilistic Assessment of Variable Slip Rates of Offshore Buried Thrusts in the Central Adriatic Sea (Italy) Since the Pliocene Time

Tectonics, Volume 45, Issue 7, July 2026.
Abstract Understanding the recent tectonic activity of buried faults represents a challenge for scientists. In the offshore portion of the Northern and Central Apennines foredeep basin in the Central Adriatic Sea, Italy, high sedimentation rates, exceeding tectonic uplift since the Pliocene, and the offshore location are hampering the detection of ...

Spatial and Temporal Distribution of Salt‐ and Shale‐Detached Contractional Deformation, Mexican Northwestern Gulf of Mexico

Tectonics, Volume 45, Issue 7, July 2026.
Abstract In the northwestern Gulf of Mexico, gravity‐driven contractional deformation is recorded across the Salina del Bravo, the Perdido and Peripheral fold belts, and the Mexican Cordilleras. Integrating seismic interpretation, structural mapping, and analysis, we examine the spatial and temporal partitioning of shortening above three principal ...

Timing of the Albano‐Hellenic Paleomagnetic Rotation

Tectonics, Volume 45, Issue 7, July 2026.
Abstract The Aegean arc is the most prominent Mediterranean salient, characterized by significant paleomagnetic rotations along its limbs. Although it is well‐established that the external Ionian and Kruja zones of the Albano‐Hellenides underwent a ∼40° post‐Oligocene clockwise (CW) rotation relative to Africa/Adria, the rotation timing remains debated.

Quantifying Thermo‐Fluid‐Chemical Coupling: Advection Governs Multi‐Phase Zonation and Self‐Sealing in a Hydrate‐Cold Seep System

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Deep fluid advection fundamentally governs the thermal‐fluid‐chemical evolution and distribution of hydrate‐cold seep systems. However, coupled relationships between deep fluid and shallow multiphase dynamics remain inadequately constrained.

Structural Evolution of a Polyphase Salt‐Tectonic System From Syn‐Rift Extension to Syn‐Orogenic Deformation in the Middle Atlas (Oum Er Rbia Region, Morocco)

Tectonics, Volume 45, Issue 7, July 2026.
Abstract Salt tectonics has received little attention in the Middle Atlas, despite the widespread occurrence of Triassic evaporites and their potential to exert first‐order control on basin architecture and deformation. This study presents the first integrated analysis of polyphase salt tectonics in the Middle Atlas, focusing on the Oum Er‐Rbia sector,

Dynamics of Antarctic and Greenland ice sheets using the borehole, radio sounding and space observations

Лëд и снег, 2016
Based on data of measurements in deep ice boreholes, as well as of radar and space geodetic observations in Antarctica and Greenland, a number of new features of the ice mass transport had been revealed.

Mud diapirs and associated intrusion structures in the Miocene Tanabe Group

The Journal of the Geological Society of Japan, 2009
田辺層群白浜累層には下位から円筒，ドーム，シル，岩脈という異なる形態の貫入岩体が見られる．市江地域の円筒状岩体は，直径数10 mで母岩をほぼ垂直に貫く．直径約150 mでドーム状の市江崎岩体は，母岩の成層構造をほとんど乱すことなく母岩のブロックや粒子を多量に取り込んでいる．岩体を中心に，放射状の泥脈・砂脈が母岩を貫く．見草岩体は長径200 mあまりのラコリス状で，その上位はシル・岩脈に富む．実験によると，粘性の低い流体が成層不良の地層中に貫入する場合は，集中した流体の鉛直上昇が円筒状通路を，粘性が高い場合はマッドチャンバーを形成した．上載圧が低く不透水層を挟む地層には段階的に貫入して，シル・ラコリス・泥脈群をつくった．田辺層群のダイアピルは白浜累層堆積時に貫入し，一部は海底面上に噴出した ...

Subsalt Depth Seismic Imaging and Structural Interpretation in Dumre Area, Albania Imagerie sismique profondeur sub-salifère et interprétation structurale dans la région de Dumre, Albanie

Oil & Gas Science and Technology, 2011
The challenge of seismic exploration in fold and thrust belt settings is to optimize the depth seismic images of the deep structural objectives beneath a complex overburden that may show strong horizontal and vertical velocity variations.
