This study presents bulk geochemical and zircon U-Pb-Hf isotopic results for the Jincheng granite and Niutouwei granodiorite in the Fuqing area, coastal Fujian Province. Coupled with previous data, this paper points out that the Jincheng granite has genetic relationship with the coeval magmatism (194~172 Ma) in the Nanling Range, implying that the subduction of paleo-Pacific plate probably started from Early Jurassic time. Consequently, the transition from the Tethys orogenic regime to the paleo-Pacific tectonic regime in the Southeast China probably occurred before Early Jurassic, approximately from 205 Ma to 190 Ma.
