[T16-O-16][Invited] Stratigraphy of Paleozoic pelagic deep-sea sedimentary rocks within the Jurassic accretionary complex of Japan
*Shun MUTO1 (1. Geological Survey of Japan, AIST)
【ハイライト講演】日本列島を構成するジュラ紀付加体に含まれる深海堆積岩は，長期間にわたる地球史を解読する上で重要な研究試料である．これまでジュラ紀付加体中の中生界の層序を中心に生層序学的研究が行われてきたが，武藤俊氏は研究例の乏しい古生界に着目して，コノドント化石を基に国際的な対比を目指した層序復元に取り組まれている．本講演では，武藤氏が古生界遠洋性堆積岩について，現在東北日本で進めている最新の知見含め紹介していただく．（ハイライト講演とは．．．）
