Chrono-stratigraphy of the Ina Group, Central Japan, Based on Correlation of Volcanic Ash Layers with Pleistocene Widespread Tephras

Uplift and denudation history of the Akaishi Range, a thrust block formed by arc‐arc collision in central Japan: Insights from low‐temperature thermochronometry and thermokinematic modeling

“…In the lower reaches of the Fuji River district, sedimentary clasts from the Akaishi Range are found in the lower to middle Pleistocene Ihara Group [ Shiba et al ., ] but not in the upper Pliocene Hamaishidake Formation [ Matsuda , ; Kano , ]. In the Ina Basin to the west and Kakegawa district to the south, the lower Pleistocene Ina Group [ Moriyama and Mitsuno , ; Moriyama , ; Matsushima , ; Suganuma et al ., ] and the lower to middle Pleistocene Ogasa Group [ Ishida et al ., ; Muto , ], respectively (Figure a), are the oldest strata‐containing sedimentary clasts from the Akaishi Range. These observations suggest that the uplift of the Akaishi Range started in the northeastern part and extended to the west and south over time [ Kano , ].…”

“…west and Kakegawa district to the south, the lower Pleistocene Ina Group [Moriyama and Mitsuno, 1989;Moriyama, 1990a;Matsushima, 1995;Suganuma et al, 2003] and the lower to middle Pleistocene Ogasa Group [Ishida et al, 1980;Muto, 1985], respectively (Figure 8a), are the oldest strata-containing sedimentary clasts from the Akaishi Range. These observations suggest that the uplift of the Akaishi Range started in the northeastern part and extended to the west and south over time [Kano, 2002].…”

“…Consequently, the uplift and denudation style of the northern Akaishi Range is explained by the simple tilted uplift model of Sueoka et al [2012, Figure 6] based on the following points: (1) the uplift is attributable only to one of the marginal faults, (2) the topographic cross section is skewed to the opposite side of the fault (Figure 3b), and (3) the thermochronometric ages are younger, and thus, denudation rates increase toward the fault (Figure 3c). This uplift model can also explain the time lag between the onset of the gravel supply from the Akaishi Range to basins to the east and west, i.e.,~3.3 Ma in the watershed area of the Fuji River to the east [e.g., Kano et al, 1985;Kano, 2002] and early Pleistocene in the watershed area of the Tenryu River [e.g., Moriyama and Mitsuno, 1989;Matsushima, 1995;Suganuma et al, 2003].…”

The phylogeography of the stag beetle Dorcus montivagus (Coleoptera, Lucanidae): Comparison with the phylogeography of its specific host tree, the Japanese beech Fagus crenata

“…It is estimated that uplift of mountains was actively occurring in the Southern Japanese Alps about 1.4–1.0 Ma and in the Central Japanese Alps at about 0.8–0.6 Ma (Suganuma et al . 2003; Sueoka et al . 2015).…”

Stages of major floral change in Japan based on macrofossil evidence and their connection to climate and geomorphological changes since the Pliocene

“…2.5 Ma (Oikawa, 2003) and then became very active between 1.5 and 1.0 Ma (Oikawa and Wada, 2004). Later, in the southern range, accelerated uplift of the Akaishi Mountain Range occurred between 1.4 and 1.0 Ma, and active uplift of the Kiso Mountain Range began at 0.6 Ma (Suganuma et al, 2003). The upheaval in and around the central highlands would have changed the local environment in basins along the Sea of Japan and may have disconnected the migration routes of plants from the Kinki District to northern basins.…”
