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 ...

Based on the reconstruction of the thermal evolution of granitoid batholith, represented by the Song‐Chai gneiss‐granite massif (Northern Vietnam), the long‐term existence of granitoid magma at deep levels of the Earth's crust (H≥25 km, Δt~20–50 Ma) is ...

Opposing shear senses in a subdetachment mylonite zone: Implications for core complex mechanics [PDF]
[1] Global studies of metamorphic core complexes and low‐angle detachment faults have highlighted a fundamental problem: Since detachments excise crustal section, the relationship between the mylonitic rocks in their footwalls and the brittle deformation

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

Patterns of Late Cenozoic exhumation deduced from apatite and zircon U-He ages from Fiordland, New Zealand [PDF]
New apatite and zircon (U-Th)/He ages from the Fiordland region of New Zealand's South Island expand on earlier results and provide new constraints on patterns of Late Cenozoic exhumation and cooling across this region.

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.

Late Cenozoic tectonic evolution of the Ailao Shan-Red River fault (SE Tibet): implications for kinematic change during plateau growth [PDF]
Surface uplift, river incision, shear zone exhumation, and displacement along active faults have all interacted to shape the modern landscape in the southeastern margin of the Tibetan Plateau.

Geochemical and petrographic re‐evaluation of ungrouped iron meteorites from Western Australia
Abstract Under the current classification scheme, ungrouped irons make up ~11% of all recognized iron meteorites. A further ~7% of iron meteorites are currently classified as simply “irons” and are yet to be fully classified. To potentially classify these meteorites, newer approaches, including either statistical modeling or advanced geochemical ...
