Geochemistry and Zircon U‐Pb Geochronology of Early Paleozoic S‐type Granites in the Eastern Qilian Block, Northwest China

The Qilian Block (QB) is a Precambrian micro‐continent located in the northeastern Qinghai–Tibet Plateau. Prevalent Lower Paleozoic granitic magmatic rocks crop out in the QB. A new integrated study of zircon U‐Pb ages and systematic whole‐rock geochemical data for the Xindian, Dongjiazhuang and Xiaogaoling granites in the eastern segment of the QB constrains their emplacement ages, petrogenesis, and regional evolutionary history. U‐Pb dating...
