【ハイライト講演】 沈み込み帯深部における超苦鉄質岩の脱水反応は，流体・熱・物質輸送を支配する重要なプロセスであるが脱水時の構造が保存された天然の例は稀である．本研究では，接触変成帯を天然の加熱実験場とみなし，稠密な鉱物・化学・密度分析から，脱水反応に伴って熱と流体が集中する稀有な描像が捉えられている． ※ハイライト講演とは．．．

【ハイライト講演】 大規模断層沿いに産する粉砕岩は，地震時の高速破壊過程を記録している可能性がある．本研究では，有馬―高槻断層帯の粉砕花崗岩について，石英と斜長石の破壊組織をフラクタル解析し，断層から離れるにつれて破砕の程度が系統的に変化することを示す．さらに鉱物ごとの亀裂進展の違いから，地震時の動的破壊過程に迫る． ※ハイライト講演とは．．．
