The zircon hafnium (ε Hf [t] +12 to +20) and oxygen (δ 18 O = 4.6‰–6.0‰) isotope compositions strongly suggest that these plutons were derived from a typical depleted mantle source. These Hf-O isotope compositions coupled with the absence of zircon inheritance indicate a minimal contribution from partial melting of either subducting slab or preexisting evolved Jurassic crust. 2018/10/8Hafnium mass fractions, and 176 Hf/ 177 Hf and 176 Lu/ 177 Hf ratios, were measured by solution isotope dilution analysis of two chips each of GZ7 and GZ8 at IGG‐CAS, Beijing. After being weighed, chips were dissolved in HF‐HNO 3 in high‐pressure bombs at 210 C for 1 week, then dried down and dissolved again in 3 mol l −1 HCl.

Hafnium isotope data suggest derivation of both tonalite and amphibolite from a depleted mantle source with minor crustal contamination. Oxygen isotope ratios in zircons range from 5.1 to 7.3‰ VSMOW, with high δ 18 O results recorded only from metamorphic domains.
