Triassic Intracontinental Crustal Reworking of the Eastern Tianshan: New Insights From Late Triassic Adakitic and Low‐Sr/Y Granitoids in the Bogda Range

Geochemistry, Geophysics, Geosystems
Continental intraplate magmatism remains a fundamental challenge in Plate Tectonics. Triassic magmatism represents a critical phase in the evolution of the Central Asian Orogenic Belt and continues to provoke debate about its tectonic setting. This study

Compositional Diversity of Early Mesozoic Granites in South Qinling: Derivation from Heterogenous Basement Rocks in the Orogenic Belt

Geosciences
Granitic rocks forming in the syn- to post-orogenic stages can trace the compositional and structural complexity of the crust beneath an orogenic belt.

U-Pb dating and geodynamics of mafic bodies at the southern margin of Lake Urmia, an evidence of Cretaceous magmatism in northwest Iran [PDF]

علوم زمین خوارزمی
In the northwestern part of the Sanandaj-Sirjan zone, mafic intrusive bodies are aligned with the trend of the Zagros orogenic belt. In this part of the Iranian lithosphere, magmatic activity occurred during three main periods: Cretaceous, Eocene, and ...

Orogenic high-T granitoids of the central Grenville Province: characteristics and geodynamic implications

Conventional models of collisional orogens predict S-type granitoid emplacement during the orogenic climax, whereas high-T (also known as A-type) granitoids, commonly associated with mantle-derived magmas, are expected to form by late-orogenic ...
