- •
The Bogda I-type felsic volcanics are intermediate ignimbrites and rhyolite lavas.
- •
The rhyolites are formed by partial melting of a hydrated and juvenile arc crust.
- •
The ignimbrites are affected by magma mingling and feldspar fractionation.
- •
It suggests that the Bogda belt was an island arc in the Late Carboniferous.
