Outline of Research at the Start

隕石に最も多く含まれる鉱物であるオリビンには、高密度化という形で母天体である小惑星の衝突履歴が記録されている。しかし、そのプロセスには未だ統一見解がない。本研究では「新たに発見された高圧相であるイプシロン相を経由する無拡散メカニズムにより、オリビンは一瞬で高密度化する」という仮説を立証するため、隕石試料や超高圧実験試料を、高分解能電子顕微鏡法やX線回折法を駆使して解析する。さらに、理論計算により、イプシロン相出現の物理化学条件の予測を行う。得られた結果を統合して、オリビンの高速相転移メカニズムを解明し、天体サイズに依存しない新しい衝撃圧力の指標を提案する。

Outline of Annual Research Achievements

2022年度に引き続き、 (Mg0.91, Fe0.09)2SiO4組成のオリビンの高圧相転移実験試料に対し、微小部X線回折（微小部XRD) 及び透過電子顕微鏡（TEM）による解析を行った。圧力12, 14, 16 GPa（温度は全て900°C）の相転移実験試料の微小部XRDパターンから、それぞれ試料では、オリビンの一部が、ワズレアイト、ワズレアイト＋リングウッダイト、リングウッダイトに相転移していることが確認された。これらの試料の詳細なTEM観察から、オリビンはその外縁部から相転移が進行しており、形成されたリングウッダイト粒子のほとんどは{110｝面の積層欠陥を持つことが明らかになった。また、これらの粒子から取得した電子線回折パターンは、リングウッダイト（Rw)の回折スポットに加えて、オリビン新高圧相であるポワリエライト(Poi)の微弱な回折スポットを示した。また、このパターンは両相のトポタキシャルな結晶方位関係(001)Poi//{001}Rw及び(100)Poi//{110}Rwを示す。一方、ワズレアイトの粒子の一部は(010)面に積層欠陥を持つが、ポワリエライトに対応する回折スポットは観察されなかった。相転移実験にて未反応であるオリビン中の転位密度は1.4-2.1x10^9 /cm2である。過去に提案された転位密度ー差応力の関係式から、差応力は0.5-0.6GPaと見積もられた。以上の結果は、ナノスケールのポワリエライトは、比較的低温かつ高い差応力条件下では、14GPa以上の圧力でリングウッダイトのみから準安定的に形成されることを示唆している。
