The ephemeral history of Earth’s youngest supra-subduction zone type ophiolite from Timor

Communications Earth & Environment, 2023
Ophiolites occur widely in orogenic belts, yet their origins remain controversial. Here we present a modern example with a geodynamic model from Timor, eastern Indonesia, where Earth’s youngest supra-subduction zone (SSZ)-type ophiolitic fragments are ...

Outboard Onset of Ross Orogen Magmatism and Subsequent Igneous and Metamorphic Cooling Linked to Slab Rollback during Late-Stage Gondwana Assembly

Geosciences, 2023
Changes in magmatism and sedimentation along the late Neoproterozoic-early Paleozoic Ross orogenic belt in Antarctica have been linked to the cessation of convergence along the Mozambique belt during the assembly of East-West Gondwana.

Subduction-related fluids influence on the Oligo-Miocene transitional magmatism of the Sulcis area (SW Sardinia, Italy) [PDF]

, 2023
The Sardinia-Corsica microplate was involved in OligoMiocene times in a SE-ward drift and counterclockwise rotation from the European margin in western Mediterranean to its current position.

Numerical Modeling of Melting Processes During Slab Break-off: Insights Into Tectonic Setting for Massif-Type Anorthosites [PDF]

Lithosphere
The concept that lithosphere detachment or break-off has long been conceived as a viable mechanism to explain prominent geological phenomena in Earth’s crust and the surface.

Geochemistry and geochronology of Carboniferous volcanic rocks from the Edren range, Trans-Altai Zone, SW Mongolia

Mongolian Geoscientist, 2022
The Edren range of the Trans-Altai zone is situated in the central south part of the Central Asian Orogenic Belt. The Edren range is composed primarily of volcano-sedimentary rocks that were weakly metamorphosed during the Devonian to Carboniferous ...

Petrological and Sedimentological Fingerprinting of Late Paleozoic Tianshan Accretionary Orogenesis from the Kangkelin Formation (Wushi, South Tianshan) [PDF]

Lithosphere
The South Tianshan Orogenic Belt (STOB) is located between the Central Tianshan Block and the Tarim Craton, and its tectonic evolution was closely associated with the Central Asian Orogenic Belt.

Age and Chemostratigraphy of the Finlayson Lake District, Yukon: Implications for Volcanogenic Massive Sulfide (VMS) Mineralization and Tectonics along the Western Laurentian Continental Margin

Lithosphere, 2022
The Yukon-Tanana terrane in the Finlayson Lake district, Yukon, represents one of the first arc–back-arc systems that formed adjacent to the Laurentian continental margin in the mid-Paleozoic. Back-arc rocks contain many large and high-grade volcanogenic
