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。

The upper Kayaoka sheet in the Atsumi area, Northeast Japan, has an alkaline-basaltic composition. The modal olivine and Ni enrichment in the lower part of the sheet indicates the accumulation of early formed olivine crystals. Overall, the average aspect ratio of plagioclase increases from the central part of the sheet toward both the top and bottom margins. The average aspect ratios of plagioclase and calculated crystallisation times at each height of the sheet, except for the lowermost margin, are roughly plotted near the regression line drawn based on those from many sills in previous research. However, we observed that the average aspect ratios of plagioclase in some horizons of the central part of the sheet exhibit an offset from the regression line. The olivine analcite dolerite in the central part of the sheet is rich in zeolite amygdules and glassy mesostasis with a quench texture. These observations suggest that the cooling rate in the central part of the sheet was faster compared with assuming conductive cooling only. A plausible mechanism for the rapid cooling at the centre of the sheet is heat transport by the convection of seawater that has infiltrated the columnar joint.
