Petrogeochemical characteristics, zircon SHRIMP U—Pb ages and Lu—Hf isotopic compositions of Late Carboniferous A‐type granitoids, Yili area, Inner Mongolia (China)

A large Late Palaeozoic A‐type granite belt lies along the Hegenshan‐Nenjiang‐Heihe belt in the Central Asian Orogenic Belt (CAOB). The Kuleqi, Naimanhe, and Gejiadian plutons at Yili are developed within this A‐type granite belt. The genesis and formation environment of these A‐type granites are controversial. The results of zircon SHRIMP UPb dating analyses indicate that the A‐type granites at Yili formed during the Late Carboniferous...
