Quartz and clinoenstatite exsolutions in clinopyroxene of garnet-pyroxenolite from the North Dabie Mountains, eastern China

摘要

The exsolution lamellae of quartz and clinoen - statite are idenfied in diopside of garnet-pyroxenolite from the North Dabie Mountain by transmission electron micros - copy, which is interpreted that the lamellae are originally exsolved from a former ultra - high - pressure clinopyroxene due to decreasing of pressure. Study of petrography shows that there is compositional zoning in the diopside itself.
