菫青石中のH₂O-CO₂のラマン分光法による検出と高温～超高温変成作用の解析への応用と意義

抄録

H2O and CO2 contents in cordierite from four different high and ultrahigh temperature metamorphic terranes have been qualitatively analyzed using Laser Raman spectroscopy. Raman spectrum of cordierite suggests that H2O is dominant for Ryoke, Namaqua and Mather metamorphic rocks, and that both H2O and CO2 are detected but are not abundant for Napier metamorphic rocks.
