- •
∼2.59–2.54 Ga volcanic rocks erupted in the Jiapigou granite-greenstone belt, NCC.
- •
∼2.7 Ga felsic gneisses are also preserved at Jiapigou area of Southern Jilin.
- •
The metavolcanic rocks were derived from juvenile crust and mantle wedge interactions.
- •
A dominant laterally crustal growth occurred in Southern Jilin at ∼2.59–2.54 Ga.
- •
The Neoarchean magmatism occurred in an Andean-type active continental margin.
