Origin and genesis of Late Jurassic to Early Cretaceous granites of the North Qinling Terrane, China

The geochemical compositions and zircon U-Pb ages of the Muhuguan and Mangling plutons of the North Qinling Terrane (NQT), China, provide insights into the basement rocks involved in magma genesis and the Mesozoic tectonic evolution of the NQT. Monzogranites from the two plutons are characterized by high SiO2 contents (69.3–77.0 wt%), low Mg numbers (0.21–0.38), enriched light rare-earth elements, Th, U, and Pb, depleted high-field-strength...
