文摘
- •
Geochemistry of sediments in the Adaminaby Group, Lachlan Orogen suggests a felsic source with continental arc signature.
- •
Granodiorites with a calc-alkaline, shoshonitic signature provided most detritus.
- •
Collisional and continental volcanic arc tectonic settings existed at time erosion of source area took place.
