Tansei-maru of the Ocean Research Institute, University of Tokyo, in December 1979. The dredged areas included the Higashi-Izu-oki submarine volcanoes and the flat-topped Omurodashi to the south of Izu-Oshima island and a peak called Niijima-urano-se located east of Niijima island. The Higashi-Izu-oki submarine volcanoes may be subdivided into the following three groups based on their petrography and chemistry: 1) the northern half of the area are all made up of rocks very much similar to those of the Higashi-Izu monogenetic volcanoes on the Izu Peninsula, composed mostly of high-alkali(high-Na2O) tholeiitic basalts and andesites. The andesites are supposed to have been derived through assimilation of granitic rocks by the basalt magma. 2) In the middle part of the area, five dredged samples are all low-alkali(low-Na2O) tholeiite series rocks arranged in an E-W to NE-SW direction. The easternmost two of these five, i.e. rocks occurring closest to Izu-Oshima island(low-alkali tholeiites) are very much similar to the rocks of the Izu-Oshima volcano and are believed to be a submarine extension of the same magma regime. The western three samples are more or less altered olivine-augite-plagioclase phyric basalts and are supposed to have been derived from submarine volcanoes older than both the Higashi-Izu monogenetic volcano group and Izu-Oshima island. 3) The southern part produced two dredge hauls with fresh high-Na2O basalts similar to the southwestern group of the Higashi-Izu monogenetic volcano group on land. Thus the Higashi-Izu submarine volcanoes appear to be composed of an eastern submarine extension of the Higashi-Izu monogenetic volcano group and the northwestern extension of the Izu-Oshima volcano and a few older submarine volcanoes which are different from the above two. The flat-topped Omurodashi submarine volcano south of Izu-Oshima island appears to consist of glassy and porous rhyolite lava flows. In the center of the edifice, a crater-like depression 1.5km\u00d70.5km wide and 100m deep was found. Rhyolite lavas are exposed on the wall of this depression. Dredged samples from the southeastern foot of an elongated submarine volcano called Niijima-urano-se, east of Niijima island were composed of fresh rhyolites, altered basalts and some quartz diorite blocks. The basalts and quartz diorites may be the basement rocks of the region. The rhylites  from Omurodashi and Niijima-urano-se are distinguished from those of Niijima and Kozushima islands in that they are higher in Na2O.", "subitem_description_type": "Abstract"}]},
