Research Abstract

Chemical and isotopic analyses of micro domains within accessory minerals in crustal rocks were carried out by using electron probe micro analyzer (EPMA) and secondary ion mass spectrometer (SIMS). Based on these data combined with the mode of occurrence and the textural relationships with other constituent minerals, the linkage between radiometric ages and metamorphic conditions/processes have been discussed in order to reveal the process of the formation of continental crust.
