文摘
- •
Southern Tianshan hosts Middle Paleozoic oceanic sediments and mafic volcanic rocks.
- •
Volcanic rocks are associated with marine chert, carbonate, siliceous shale and turbidite.
- •
Volcanic rocks possess geochemical features of OIB with subordinate MORB.
- •
The dominating OIBs were derived from low-degree melting of garnet peridotite.
- •
Wide age range of OIBs and their domination in OPS suggest a relatively large oceanic realm.
