Abstract
Abstract The Garze–Litang suture zone, located in the eastern part of the Tethyan tectonic domain, is notable for widespread Late Triassic granitic plutons, which are genetically associated with the evolution of the Paleo–Tethys Ocean. The Daocheng granitic pluton in the eastern Yidun Arc, SW China, is located in the middle of the Garze–Litang suture zone and has an outcrop area of ∼2800 km 2 . In the present study, we report zircon U–Pb ages and elemental and Sr–Nd–Hf isotopic data for the Daocheng granitic intrusion. Secondary ion mass spectrometry and laser ablation inductively coupled plasma mass spectrometry U–Pb analyses on zircons yield consistent ages of ca. 216 Ma for three samples from the pluton. All the Daocheng granitic rocks are enriched in Si (SiO 2  = 68.1–76.4%) and large-ion lithophile elements but depleted in high-field-strength elements (e.g., Nb, Ta, and Ti). Mineralogical and geochemical features indicate that these are high-K and calc-alkaline and I-type granites. They are characterized by relatively variable initial 87 Sr/ 86 Sr ratios (0.7059–0.7102), negative e Nd ( t ) values (−5.7 to −7.8), wide-ranging e Hf ( t ) values (−9.8 to +3.4), and two-stage Hf model ages of 1.04 to 1.88 Ga. These isotopic signatures indicate that the source for the Daocheng granite was probably derived from partial melting of a Late Paleoproterozoic to Early Mesoproterozoic mafic–intermediate lower crust with a variably minor addition (
