Rapid Slab Rollback Drives Early Cretaceous Back‐Arc Extension in NE China: Implication for Crustal Growth and Episodic Porphyry Mineralization

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract The subduction of the Paleo‐Pacific Plate beneath the NE Asian continental margin induced extensive magmatism, providing an excellent opportunity to investigate the interplay between plate dynamics, arc magmatism, continental crust formation, and porphyry mineralization.

Rethinking Seawater Mo Isotope Mass‐Balance and the Sedimentary Mo Record

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 3, March 2026.
Abstract A lingering misconception is that seawater 98Mo/95Mo ratios should have increased more or less linearly with the oxygenation of Earth's oceans. At the root of this hypothesis is the generalization that oxidizing marine sediments have a stronger affinity for lighter‐mass Mo isotopes than their reducing counterparts.

The Paleo‐Tethys Suture Zone in the Afghan Hindu Kush‒Pamir: Geo‐Thermochronology, Geochemistry, Tectonics

open access: yesTectonics, Volume 45, Issue 3, March 2026.
Abstract In the Afghan Hindu Kush, the 223–209 Ma (≤800°C) Salang batholith is part of the Silk‐Road magmatic arc that was built on ∼40‐km‐thick Turan‐Karakum block continental crust. The batholith constitutes the hanging wall of the Herat‐Panjshir‐Badakhshan—the Paleo‐Tethys—suture zone, vestige of the subducted Paleozoic‐early Mesozoic Paleo‐Tethys ...

Update Heat Flow Density Map for Portugal [PDF]

open access: yes, 2010
New thermal conductivity, heat production and temperature data obtained in Portugal were used to produce a new heat flow density map. Heat flow density values in Portugal vary between 42 and 115 mW/m2 and allow the extrapolation of temperatures to depths

Depositional Interplay Between the Ancestral Rocky Mountains and Ouachita–Marathon–Sonora Orogenies: Insights From Provenance Records in the Late Palaeozoic Marfa Basin, West Texas, USA

open access: yesBasin Research, Volume 38, Issue 2, March/April 2026.
Provenance records from the late Palaeozoic Marfa Basin in West Texas reveal the transition from the Ancestral Rocky Mountains to the Ouachita–Marathon–Sonora orogenies during the early Permian in SW Laurentia. ABSTRACT The Marfa Basin in West Texas is a late Palaeozoic synorogenic depocenter associated with regional deformation linked to the Ancestral

Quantifying Multi‐Source Sediment Supply in a Tropical Foreland Basin (Oligocene‐Miocene Nyalau Formation, Borneo)

open access: yesBasin Research, Volume 38, Issue 2, March/April 2026.
Detrital zircon unmixing identifies three sediment sources for the Oligocene–Miocene Nyalau Formation, including a previously unrecognised syn‐depositional component characterised by Oligocene–Miocene volcanic zircons and Neoproterozoic populations absent from established sources.

Lithospheric Mantle Heterogeneity Drives Delayed Magmatism and Wide Continent‐Ocean Transitions in Rifted Margins

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract The formation of wide, magma‐starved continent–ocean transition (COT) zones remains incompletely understood. We use 2‐D thermo‐mechanical numerical experiments, coupling hydrous mantle melting with parameterized crustal accretion, to explore controls on magmatic lag: the delay between continental crustal break‐up and steady oceanic crustal ...

Multi‐Scale Electrical Conductivity Model of the Contiguous United States

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract The completion of the Magnetotelluric (MT) USArray across the contiguous US enables continental‐scale 3‐D imaging of the asthenosphere‐lithosphere electrical structure. We present a novel 3‐D model of the contiguous United States (MECMUS), derived from a single inversion of the now‐completed USMTArray data set.
