9:00 AM - 9:15 AM

[T9-O-1] [Invited] Classification of the Cretaceous granitoids of northern Kyushu – Proposal focusing on the Itoshima granodiorite

【ハイライト講演】

*Yayoi MURAOKA¹, Kazuhiro MIYAZAKI¹ (1. Geological Survey of Japan, AIST)

世話人よりハイライトの紹介：北部九州白亜紀花崗岩バソリス群の中で最大の分布面積を誇る糸島花崗閃緑岩については, これまで単一のマグマ活動で形成された岩体なのか議論があった. 本講演は,詳細な野外調査により新たに見出した記載岩石学的特徴の異なる岩体の報告など, 糸島花崗閃緑岩について岩体再区分・細分化の可能性を提案するものであり, フィールドジオロジスト必聴の講演である.※ハイライトとは
