A possible paleorift zone in the Central Dharwar Craton of South Indian Shield: Evidence from regional gravity anomalies

Geosystems and Geoenvironment, 2023
A conspicuous zone marked with linear Bouguer gravity anomalies encompassed with overall regional gravity high zone spreads about 5° length and width of about 1 to 1 1/2° in the central part of Dharwar Craton is not entirely relatable to surface ...

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 ...

The Effects of a Microplate on Plume‐Ridge Interactions: Constraints From Comparing Easter and Juan Fernandez Microplates in the Eastern Pacific Ocean

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract This study investigates the nature of plume‐ridge interactions near a tectonic microplate using mantle Bouguer anomaly (MBA) gravity calculations. The focus of this investigation is a comparison of the Easter and Juan Fernandez microplates, which are located in the eastern Pacific Ocean along the Pacific, Nazca, and Antarctic plate boundaries.

Seismic Reflection Profiling at the Kentland Impact Structure, Indiana: Geophysical Characterization of Impact Induced Damage

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract The Kentland Impact Structure is a classic complex crater whose central peak is exposed in an active quarry in NW Indiana, USA. However, its diameter has remained poorly constrained due to the thick glacial sediment cover. Newly obtained seismic reflection profile images combined with refraction seismic tomography, earlier gravity surveying ...

Geology and Chronology of the Lunar Taruntius Crater: Implications for the Retention Age of Lunar Ray Patterns and Lifetime of Lunar Explosive Volcanism

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract The Taruntius crater, situated between Maria Fecunditatis, Crisium, and Tranquillitatis, is characterized by a prominent bright ray system and a floor‐fractured morphology and has long been interpreted as a relatively young Eratosthenian or Copernican crater.

Confirming the impact origin of the São Miguel do Tapuio structure, northeastern Brazil

Meteoritics &Planetary Science, Volume 61, Issue 7, Page 1263-1287, July 2026.
Abstract The São Miguel do Tapuio structure (SMT) is a remarkable, nearcircular feature of about 21 km diameter, centered at 5°37.6′ S, 41°23.3′ W in Piauí state, northeastern Brazil. The structure is located within the sedimentary strata of the Paleozoic–Mesozoic Parnaíba Basin and predominantly comprises sandstones of the Devonian Pimenteiras and ...

Geophysical investigation of the Santa Marta impact structure—Piauí State, Brazil

Meteoritics &Planetary Science, Volume 61, Issue 7, Page 1399-1416, July 2026.
Abstract The Santa Marta impact structure in northeastern Brazil, recognized as a partially preserved complex crater, was investigated through an integrated geophysical study employing magnetotelluric (MT) and gravity methods. Our research provides constraints on the crater's subsurface architecture.

Ridge Migration and Plate Boundary Readjustments at the Rodriguez Triple Junction

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The Rodriguez Triple Junction (RTJ) marks the intersection of the Indian Ocean's three principal mid‐ocean ridges and is a type locality for Ridge‐Ridge‐Ridge triple junctions. A local seismic network was deployed for 8 months to monitor seismicity around the RTJ and the adjacent Central Indian Ridge (CIR).
