Research Abstract

本年度は、急冷回収実験により、地球深部で生成されるマグマの含水量を制約する実験を行った。また、高温高圧下での含水マグマの混和不混和現象の解明を行う実験を行った。これらの研究により、上部マントル下部からマントル遷移層で生成するマグマの含水量は温度圧力が一定の場合ユニークに決定され、また圧力よりも温度依存性がかなり大きいことが明らかとなった。また、上部マントル浅部では従来の報告通り、含水マグマと流体の不混和現象がみられ、圧力上昇とともに消滅していく様子も明らかにされた。さらに、マントル鉱物(固相)中に取り込まれる水の量、及びその影響を明らかにすることも重要であり、マントル鉱物中に固定される含水量・分配、及びその相転移境界における水の影響のデータをまとめた論文も執筆した。
上記の研究に加えて、放射光X線その場観察実験により、1)蛇紋石の脱水分解反応カイネティクス実験、2)蛇紋石の状態方程式の実験、3)無水含水アルバイトメルトの構造の実験、等を行った。これらについては、一部論文執筆済み、また論文執筆中である。また、マグマの弾性波速度測定実験も進行中で、今年度は特に技術開発が中心であったが、上部マントルの条件下でシグナルが収集できることが明らかとなった。さらに、今年度はフィールド経験が豊富な研究分担者が加わったことにより、フィールドで観察される現象と実験データを密にリンクさせた研究を遂行している。また、このような高温高圧実験技術を利用した各種実験も同時に遂行している。
