• Origin of igneous layering and related structures in the Murotomisaki Gabbroic Intrusion—Remelting of crystal mush by fluid migration within the crystallizing boundary layer

  Takashi Hoshide

  Single author

  層状貫入岩体に見られる層状構造の形成モデルとして、マグマ溜まりの固液境界層内での流体相の移動により一度作られたクリスタルマッシュが再溶融を起こし、局所的にメルトフラクションが増加した部分で固液分離が促進されて層状構造が発達するというモデルを提唱した。つまり層状貫入岩体に発達するある種の層状構造は、マグマ溜まりが結晶化していく際のfluid pathwayであることを主張した。
