U–Pb zircon, geochemical and Sr–Nd–Hf isotopic constraints on the age and origin of Early Palaeozoic I-type granite from the Tengchong–Baoshan Block, Western Yunnan Province, SW China

Herein we present new U–Pb zircon ages, whole-rock geochemical data and Nd–Sr–Hf isotopic data for an Early Palaeozoic monzogranite batholith from the Tengchong–Baoshan Block, Western Yunnan Province, China. Mineralogical and geochemical features suggest that this granitoid is a high-K, calc-alkaline, I-type granite. SHRIMP and laser ablation ICP-MS (LA-ICP-MS) analysis of zircon yields ages of between 499 ± 5 Ma and 502 ± 5 Ma, for three...
