Petrogenesis of the Late Mesozoic Guposhan composite plutons from the Nanling Range, South China: Implications for W-SN mineralization

Voluminous granite plutons were emplaced in the Late Mesozoic in the Nanling Range, South China, accompanied by large-scale polymetallic deposits. Most plutons are composite, composed of major-phase granites and highly differentiated late-stage granites. Previous studies have proposed fractionation of both granite types and polymetallic deposits from a common magma. We choose to study the ages, chemistry and Nd-Hf isotopes of the Guposhan...
