The study area is on the southeastern end (the Nemuro Peninsula) of Hokkaido Island, the northernmost island of Japan, which is at the western end of the Kuril Arc (Fig. 1). The Kuril Arc is a subduction zone that extends from Hokkaido Island to the Kamchatka Peninsula in eastern Russia.

The Cretaceous System in the Japanese IslandsAuthor: Cretaceceous Research Committee. Introduction. The Sorachi–Yezo Belt (Kiminami et al. ) in central Hokkaido, Japan, is composed of three geological units: the Sorachi Group, the Yezo Supergroup and the Kamuikotan Sorachi Group is a peculiar accretionary complex characterized by numerous occurrences of greenstones, which extend for approximately km from north to south in central Hokkaido ().

      The breakup of Rodinia about million years ago formed the Panthalassa ocean, with rocks that eventually became Japan sitting on its eastern margin. In the Early Silurian ( million years ago), the subduction of the oceanic plates started, and this process continues to the present day, forming a roughly km wide orogeny at the convergent boundary.   We here describe a new Early Cretaceous (early Albian) eutherian mammal, Sasayamamylos kawaii gen. et sp. nov., from the ‘Lower Formation’ of the Sasayama Group, Hyogo Prefecture, mamylos kawaii is characterized by a robust dentary, a distinct angle on the ventral margin of the dentary at the posterior end of the mandibular symphysis, a lower dental formula .

Upper Cretaceous foraminifera from the Rumoi Coal Field, Hokkaido, Japan (Report / Geological Survey of Japan)Author: Osamu Fukuta. “Dinosaur fossils from Japan are exceptionally rare and most material is extremely fragmentary.

The finding of this single tooth does indicate that during the latter stages of the Late Cretaceous, this part of the world was home to large Tyrannosaurs similar to those found in similar aged rocks in North America and elsewhere in Asia.”. The Cretaceous Yezo Group, exposed in central Hokkaido, northern Japan, was probably deposited at about 35–45°N (Hoshi and Takashima,Kodama et al., ) along a westward subduction margin in the north-eastern Asian continent during the group consists of a 10,m-thick forearc sedimentary sequence of sandstones and mudstones with subordinate by: Mid-Cretaceous strata in central Hokkaido exhibit east–west lithofacies changes that are the most remarkable within the Yezo Group.

The source of Cretaceous sediments was to the east (Tanaka, ), whereas western marginal facies such as coastal, shoreface and inner-shelf sediments are widely present in the Ikushumbetsu area ().The inshore, shallow-water facies comprises the Mikasa Cited by: The Japanese islands were part of the active continental margin of Asia until the opening of the Japan Sea in the Miocene.

PY - Y1 - N2 - The Cretaceous sediments of Hokkaido are composed of miogeosynclinal and deltaic sediments from the Aptian to the Maastrichtian, distributed in two belts westward of the paired metamorphic belts.

New 40ArAr total fusion ages have been obtained on sanidine from tuffs in the zone of Mantelliceras saxbii (equivalent to the same subzone of the European ammonite zonation) and the zone of Graysonites wooldridgei (equivalent to the European subzone of Neostlingoceras carcitanense).

The Cretaceous (/ k r ɪ ˈ t eɪ. ʃ ə s /, krih-TAY-shəs) is a geological period that lasted from about to 66 million years ago (mya). It is the third and final period of the Mesozoic Era, as well as the name is derived from the Latin creta, "chalk".It is usually abbreviated K, for its German translation Kreide.

The Cretaceous was a period with a relatively warm climate.

The (δ 18O values of nine Cretaceous granitic rocks from the low P/T type regional metamorphic zone of Japan are + to +‰ relative to SMOW, while ten Cretaceous granitic rocks from the non-metamorphic zone are + to +‰.

The 18O-enrichment in the former rocks is mainly attributed to oxygen isotopic exchange between the granitic magma and the surrounding metamorphic rocks during.
