概要

• 論文の詳細を見る

• Quartz pseudomorphs after coesite were discovered in garnet from a pelitic garnet-chloritoid-talc schist. The pseudomorphs accompany radial cracks developed from them. A metamorphic condition of low temperature (<600°C) and very high pressure (>2.4GPa) is estimated from the mineral assemblage and mineral compositions. Sedimentary rocks were brought to the depth of about 80km or more by subduction of oceanic lithosphere or by collision of two continents.
