Özet

Coesite partially inverted to quartz occurs as an inclusion within dolomite in a calc-silicate rock in Dabie Shan, China. The calc-silicate rock consists mainly of dolomite, calcite, quartz, and phengite that is partially replaced by phlogopite, plagioclase, and secondary phengite. The calc-silicate intercalated with marble forms an over 8-m-thick band in felsic gneiss. The presence of coesite within dolomite in calc-silicate rocks confirms that sedimentary rocks deposited on continental crust can be subducted to depths of over 100 km, and that even a carbonate mineral like dolomite is able to preserve coesite during the process of eduction. -from Authors
