Abstract The northern extent of Greater India is a critical, yet highly debated, parameter for reconstructing the India‐Asia collision. Previous paleomagnetic estimates, including the fill‐the‐gap and fixed great circle approaches, yield widely varying results, spanning from ∼200 to ∼3,000 km. These large discrepancies stem principally from two primary

Abstract The nature of mantle sections exhumed at magma‐poor rifted margins remains poorly constrained, largely because direct sampling of mantle in modern passive margins is exceptionally rare. The Iberia–Newfoundland system is unique in providing drilled mantle rocks on both conjugate margins, offering an unprecedented glimpse into mantle ...

Hydrothermal Vent Complexes Associated With the Infinity Sill (Vøring Basin, Offshore Norway)
Abstract The emplacement of igneous sill intrusions induces rapid heating of host rocks, generating fluids that migrate through structures known as hydrothermal vent complexes (HTVCs). While sill geometry and permeability are considered important factors controlling fluid migration around igneous sill intrusions, the precise mechanisms controlling vent

Abstract The paleogeographic position of the South China Block (SCB) during the early Paleozoic and its affiliation with Gondwana remain debated. We report new high‐quality paleomagnetic data from sandstone‐dominated Cambrian Stage 3 strata correlated with the Yu'anshan–Hongjingshao succession collected along the southwestern margin of the SCB ...

Abstract Playa lakes are considered promising landing sites on Mars because of their strong astrobiological potential. Therefore, sediments and buried structures in terrestrial playa lakes have become the focus of numerous analogue studies. The inclusion of ground penetrating radar (GPR) in the payloads of Martian missions has opened new avenues for ...

Abstract Subsurface microbial ecosystems associated with hydrocarbon reservoirs are shaped by temperature, salinity, redox gradients, and fluid flow. However, the drivers of microbial activity and hydrocarbon biodegradation over geologic timescales remain poorly constrained.

Abstract Following continental collision, the distal European margin was overridden by the Alpine wedge and is now largely concealed beneath the mostly intact orogenic lid. Consequently, the geological evolution and nature of the hidden basement domains remain poorly constrained.

Abstract Normal‐fault growth, segmentation, and their relationships with crustal inheritance and rheological layering are investigated in a post‐thrusting setting of the southern sector of the Northern Apennines. We integrate 3D modeling with gravity, thermal, and seismological constraints to reconstruct the geometry and evolution of the main normal ...
