Kenta Kawaguchi 研究室（広島大学）

AI 要約（直近 5 年の研究成果）

Kawaguchi研究室では、地球の内部で起こる岩石の変成・変形プロセスと、大陸や島弧の形成・衝突メカニズムを解明する研究を行っています。具体的には、沈み込み帯で生成された高圧低温型の変成岩や、マグマが冷え固まった火成岩を対象とし、複数の分析手法を組み合わせて調査しています。ジルコンという鉱物に含まれるウラン・鉛同位体の年代測定、全岩化学組成の分析、化学元素の比率測定などを用いて、岩石がいつ、どのような環境で形成されたかを明らかにしています。研究の地理的範囲は広く、日本の西南部や朝鮮半島、ベトナム、エジプトなど、東アジアと周辺地域の地質構造に焦点を当てています。特に、古生代から中生代にかけて東アジア大陸の周辺で起こった火山活動や盆地の閉鎖、島弧の衝突といった大規模な地殻変動の記録を岩石に読み取っています。これらの研究から、太平洋プレートの沈み込み角度の変化に応じた火成活動の移動、異なる起源を持つ地塊の相互作用など、プレートテクトニクスの長期的な変遷が明かされています。
