These grabens are aligned en echelon. The \"\"Iheya\"\" Graben is the most pronounced. No positive evidence was found for the existence of transform faults connecting the en echelon grabens. A basaltic ridge and knolls were newly found in the central axis of these grabens. From these central knolls and the ridge pieces of olivine basalt were dredged. These are island arc type high alumina basalts with K-Ar ages younger than 1 Ma. Some rhyolite, dacite and a small quantity of dacitic andesite younger than 1 Ma (K-Ar and fission track ages) were also dredged in the vicinity, indicating bimodal volcanism. Thus, the petrologic evidence does not support the existence of an oceanic crust but it suggests an extensional stress field in the middle Okinawa Trough. Based upon the evidence, the middle Okinawa Trough is concluded to be in a rifting stage of an incipient spreading process in the continental margin.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"128154","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kimura, Masaaki"}]},{"nameIdentifiers":[{"nameIdentifier":"128155","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kaneoka, Ichiro"}]},{"nameIdentifiers":[{"nameIdentifier":"128156","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kato, Yuzo"}]},{"nameIdentifiers":[{"nameIdentifier":"128157","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Yamamoto, Satoshi"}]},{"nameIdentifiers":[{"nameIdentifier":"128158","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kushiro, Ikuo"}]},{"nameIdentifiers":[{"nameIdentifier":"128159","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Tokuyama, Hidekazu"}]},{"nameIdentifiers":[{"nameIdentifier":"128160","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kinoshita, Hajimu"}]},{"nameIdentifiers":[{"nameIdentifier":"128161","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Isezaki, Nobuhiro"}]},{"nameIdentifiers":[{"nameIdentifier":"128162","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Masaki, Hideko"}]},{"nameIdentifiers":[{"nameIdentifier":"128163","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Oshida, Atsushi"}]},{"nameIdentifiers":[{"nameIdentifier":"128164","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Uyeda, Seiya"}]},{"nameIdentifiers":[{"nameIdentifier":"128165","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Hilde, Thomas W.
