    Identification and significance of "gneissic" magma-mixed complex in the Changle-Nan'ao fault zone, southeastern Fujian, China

    • Various magma-mixed plutonic rocks formed by physical and chemical mixings in Cretaceous dioritic and monzogranitic magmas have been discerned in the Changle-Nan'ao Fault Zone of southeastern Fujian Province during recent regional geological surveys. Magma-mixed rocks and their two end-member rocks comprise magma-mixed complex, and underwent stress affect after emplacement. They were misunderstand as migmatites or gneissic granites formed by metamorphism and deformation for a long period due to their specific texture. This paper describes field geologic appearances of magma-mixed complex exposed in Xiaocuo of Quanzhou and Gaoshan of Fuqing, their petrological diversities with typical both deformed granite in Putian and granitic gneiss in Fuqing, and infers that magma-mixed plutonic rocks were emplaced in an extensional setting during early period of Early Cretaceous, earlier than main metamorphism-deformation phase.
