摘要
Most of the quartzofeldspathic rocks in the Fuping complex of the trans-North China orogen bear a large quantity of leucocratic veins, dykes and granitic intrusions. Migmatization can be manifested with prominent melt injections in the felsic gneisses and faint dispersed melt crystallization in the competent quartzite of the Wanzi series metasedimentary rocks. In the process of melt infiltration migmatization, the rock composition was changed and the system was open in chemistry. Due to crystallization of the infiltrated melt, some zircons of magmatic feature may be formed and can be easily mistaken as detrital zircons in metasedimentary rocks.
