 note = {We newly discovered rift-related alkali feldspar granite clasts consisting of perthitic alkali feldspar, quartz, arfvedsonite and/or aegirine from Jurassic conglomerate beds in the Murihiku Terrane, New Zealand. The alkali feldspar granite clasts are rare (ca. 1-2% of total clasts) and occur together with various volcanic and plutonic clasts. This discovery provides a possible key to reconstruct paleogeographic and paleotectonic settings of the 'volcanic arc-related' Murihiku Terrane in the eastern margin of Gondwanaland. We describe here new occurrence, geochemical and geochronological data about alkali feldspar granite clasts. Their chemical features are characterized by 'A-type' granite such as high value of Nb, Ga, and Y and high ratio of Ga/Al. Geochronological results (156±8 Ma and 212±11 Ma) by K-Ar whole-rock dating method indicate that a possibility of two distinct batholiths existed as sources of the alkali feldspar granite clasts. The clast ages suggest a tectonic link between the Murihiku Terrane, the Median Batholith (Median Tectonic Zone) and West Antarctica. They are important clues to reveal the tectonics of the Mesozoic Gondwanaland margin., 国立情報学研究所で電子化したコンテンツを使用している。},
