This study presents bulk geochemical and zircon U-Pb-Hf isotopic results for the Jincheng granite and Niutouwei granodiorite in the Fuqing area, coastal w:st="on">w:st="on">Fujian w:st="on">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 w:st="on">w:st="on">Nanling w:st="on">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 w:st="on">Southeast China probably occurred before Early Jurassic, approximately from 205 Ma to 190 Ma.
