Geochemistry and Geochronology of A‐Type Intermediate‐Felsic Rocks in NW Himalaya, Pakistan: Implications for Petrogenesis and Tectonic Evolution of Northern Gondwana

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 1, January 2025.
Abstract Igneous intrusives in northern Pakistan can provide valuable insights into pre‐Himalayan metaluminous to peraluminous magmatism along the northern boundary of the supercontinent Gondwana and its potential tectonic significance. This study generates new geochronologic, petrographic and geochemical data for intermediate (monzonite, syenite, and ...

Tectonic Evolution of the Proto‒Tethys in the Early Devonian: Insights From the Turbidite in the North Qilian Belt, NW China

Earth and Space Science, Volume 11, Issue 6, June 2024.
Abstract The Devonian tectonic setting is still controversial in the Proto‒Tethyan North Qilian belt. The Hexi Corridor of the North Qilian belt occupies a key position in constraining the tectonic evolution of the Proto‒Tethyan Ocean and the growth of the Asian continent.

Impact of Depth‐Dependent Heterogeneity in Aquifers on the Response of Unsaturated‐Saturated Flow to Earth Tides

Water Resources Research, Volume 60, Issue 6, June 2024.
Abstract Heterogeneity is a natural characteristic of aquifers, which has a profound influence on groundwater flow and solute transport. However, the heterogeneity in an aquifer is difficult to characterize and its impact on groundwater response to Earth tides remains insufficiently explored.

Late Triassic Intracontinental Deformation of South Tianshan, Central Asia: Evidence from Syn‐tectonic Sedimentation and Detrital Zircon Provenances of the Kuqa Depression

Acta Geologica Sinica - English Edition, Volume 98, Issue 3, Page 548-568, June 2024.
Abstract The Tianshan range, a Paleozoic orogenic belt in Central Asia, has undergone multiple phases of tectonic activities characterized by the N–S compression after the early Mesozoic, including the far‐field effects of the Cenozoic Indian–Asian collision.

Re-Evaluating A-Type Granite Petrogenesis: Formation during Ocean Opening [PDF]

Lithosphere
A-type granites are commonly emplaced in extensional settings, including post-collisional, intraplate, and back-arc environments. This study delves into the early Permian A-type granite and its felsic enclaves from the southern Beishan orogenic belt, a ...
