Abstract

Preface: Le Tour de Mino We make the six-day-long excursion that nearly northeast-southwest traverses the central Japan. The trip starts from the Takayama area in Hida Massif, travels down to south in Mino Massif, and ends at the Neo area. The excursion focuses upon the observation and discussion of the lithology and structure of the Permian to Jurassic rocks of the Mino belt, the most thoroughly studied, Jurassic subduction-generated accretionary complex of Japan. The rocks to examine during the excursion include Permian basaltic rocks, chert, and shallow-marine carbonates, Triassic to Jurassic chert and related siliceous rocks, and Jurassic terrigenous clastic rocks. Having a Panthalassic affinity, the accreted rocks of the Mino belt could offer a unique opportunity to realize similarities and dissimilarities between the Panthalassic rocks and Tethyan rocks. We also make several stops to observe high T/P metamorphic rocks of the Hida belt with a Sino-Korean (North China) affinity, Upper Paleozoic sedimentary and volcanic rocks of the Hida-gaien belt, and Jurassic granitic rocks in Hida Massif. The Hida-gaien belt is lying between the Hida belt to the north and the Mino belt to the south. We also observe post-orogenic, Late Jurassic-Early Cretaceous fluvial-lacustrine sediments covering older rocks of the Hida and Hida-gaien belts.
