206Pb/238U dating of detrital zircons by LA-ICP-MS clarified that the majority of high-P/T Nagasaki metamorphic rocks in western Kyushu contain Late Cretaceous igneous zircon of 89 ± 3 Ma (Turonian-Coniacian) and 86 ± 2 Ma (Coniacian-Santonian). These data indicate that Nagasaki metamorphic rocks are composed mainly of Upper Cretaceous Shimanto metamorphic rocks, i.e. high-P/T metamorphosed accretionary complex of the Cretaceous Shimanto belt. This find strongly supports the subhorizontal geotectonic structure of the Japanese Islands previously inferred from surface geological mapping and deep seismic images.
