- •
Geochemical compositions of mafic rocks outcropped in the Luobusa ophiolite are studied.
- •
Both gabbros and amphibolites of the Luobusa ophiolite are dated.
- •
The Luobusa ophiolite was formed at the Early Cretaceous, i.e., ~ 130 Ma.
- •
The formation age is roughly synchronous to its metamorphic sole.
- •
Ophiolites along the whole YZSZ were coevally formed during the Cretaceous.
