Long‐Distance Lateral Magma Propagation and Pamir Plateau Uplift

Long-distance lateral magma propagation may reflect the complex interaction between regional tectonics and crustal uplift. Here, we report observations on Taxkorgan intrusive (TIC) of Central Pamir. TIC is a 70 km long, 10–18 wide, north-northwest–elongated body intruded into mid-upper crust in parallel with, close to, Kongur Shan Extensional System. New zircon U-Pb dating shows that syenite samples exhibit clear younging pattern from south to north along pluton axis within an interval 11.5 10.3 Ma, which interpreted as single feeder zone at its northwestern margin. The was caused by combination rigidity differences, topography-induced pressure gradient nearly orthogonal least compressive stress. We propose long-distance plays important role plateau expansion, restraining thickness elevation Pamir Plateau.
