文摘
- •
Backstop can be identified from deformation features of forearc basin sequence.
- •
Static backstop is generated by age difference from hiatus in subduction process.
- •
The igneous activity in middle Miocene contributes to originate lithified backstop.
- •
Backstop controls fault system within accretionary prism including ancient splay fault.
- •
Backstop distribution could relate to the coseismic rupture segment.
