英文摘要Early mantle differentiation is yet to be well constrained because isotopic systems recorded in many ancient rocks are arguably susceptible to later disturbances. Although refractory zircon is of singular importance in deciphering early Earth history, a growing body of work on ancient zircons indicates that interpretations of their U-Pb ages and Hf-O isotopes are neither straightforward nor unique. Owing to these complexities, the question of whether the Anshan Complex of North China Craton (NCC) really preserves 3.8 Ga rocks remains controversial. To better understand these issues, we conducted a systematic in situ zircon U-Pb, Hf and O isotopic study guided by detailed field mapping (1:50 scale) and sampling at Guodishan, northern Anshan Complex. Three rock units were recognized and precisely dated: a ca. 3.13 Ga massive trondhjemitic gneiss that dominates the outcrop, a ca. 3.36-3.30 Ga migmatite complex that is intruded by the trondhjemitic gneiss, and a ca. 3.81 Ga massive to weakly-banded trondhjemitic gneiss that is enclosed by the migmatite complex.
