Peraluminous granitoid magmatism from isotopically depleted sources: The case of Jing'erquanbei pluton in Eastern Tianshan, Northwest China

The Eastern Tianshan region is a critical segment of the Central Asian Orogenic Belt (CAOB), one of the largest Phanerozoic accretionary orogenic belts in the world. Several pulses of isotopically depleted Late Palaeozoic calc‐alkaline and high‐K calc‐alkaline granitoid magmatism are known to be associated with the collisional orogeny in the CAOB. However, no systematic studies have been conducted on the peraluminous granites that were formed...
