Slab‐Mantle Interaction During Subduction Initiation: Constraints From Trace Element and Sr‐Nd‐Pb Isotope Systematics of Boninite and Other Magmas and Metamorphic Sole in the Oman Ophiolite

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract The Late Cretaceous Oman ophiolite includes a series of volcanic rocks generated during the transition from spreading ridge to protoarc associated with subduction initiation. We analyzed major and trace elements and Sr, Nd, and Pb isotope compositions of lavas and dikes of the protoarc stage, especially boninites. We also analyzed amphibolites

Synextensional Granitoids and Detachment Systems Within Cycladic Metamorphic Core Complexes (Aegean Sea, Greece): Toward a Regional Tectonomagmatic Model

Tectonics, 2018
Within deforming continental regions where metamorphic core complexes (MCCs) and synextensional granitoids are closely associated, deciphering the link between detachment faulting and magmatism often remains complex as (1) the rheological weakness of ...

Petrogenesis of the Late Oligocene Takht batholith, Southeastern Iran: Implications for the Diachronous Nature of the Arabia–Eurasia Collision

Frontiers in Earth Science, 2020
Zircon U-Pb age, mineral compositional, elemental and Sr-Nd isotopic data are documented for intermediate to felsic rocks in the Takht batholith, a Late Oligocene igneous complex in the southeastern segment of the Urumieh-Dokhtar belt, Iran, to ...

Evolution and Provenance of the Polish Rotliegend in the Southern Permian Basin

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 2, February 2026.
Abstract The Southern Permian Basin (SPB) has been extensively explored for ore deposits. However, a comprehensive evaluation of the remaining copper potential, specifically for sediment‐hosted stratiform copper system, remains lacking. This study applies goSPL, an open‐source landscape and stratigraphic evolution model, to reconstruct the Permian rift‐

Subglacial Topography of Coats Land Records Post‐Gondwanan Landscape Evolution and Early Ice‐Sheet Behavior in East Antarctica

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 2, February 2026.
Abstract The East Antarctic Ice Sheet (EAIS) formed circa 34 million years ago and now contains an ice volume equivalent to ∼52 m of global sea‐level rise. Although the EAIS is approximately in balance today, there is substantial uncertainty regarding the sensitivity of sectors underlain by low‐lying bed topography to future climate and ocean warming ...

EARLY NEOPROTEROZOIC GRANITOIDS IN THE RYAZANOVSKY MASSIF OF THE YENISEI RIDGE AS INDICATORS OF THE GRENVILLE OROGENY AT THE WESTERN MARGIN OF THE SIBERIAN CRATON

Геодинамика и тектонофизика
Studies of the geological history of the Yenisei Ridge are important not only for understanding the tectonic evolution of mobile belts at the boundaries of ancient cratons but also for problem solving whether the Siberian craton was a part of the Rodinia

Mineralization Characteristics of the Li‐rich Muscovite Granite in the Mufushan Batholith, Central China: Insights into the Rare Metal Mineralization Models of Batholithic Complex

Acta Geologica Sinica - English Edition, Volume 100, Issue 1, Page 137-155, February 2026.
Abstract Elucidating the mineralization mechanisms of individual granitic stages and tracing magmatic evolution processes are critical for establishing mineralization models of large‐scale batholiths. The Mufushan granitoid batholith, renowned for multistage magmatism and large‐scale rare metal mineralization, mainly comprises biotite, two‐mica, and ...

Geology of the central Kohistan Arc, Northern Swat, Kalam (NW, Pakistan), results of a new 1:50,000 scale geological mapping

Journal of Maps
The study area in, northern Swat, Pakistan represents a critical segment of the Cretaceous to Tertiary Kohistan arc. It is characterized by complex interplay of plutonic, volcanic and metamorphic systems, whose magmatic and tectonic relationships remains
