文摘
- •
Discriminant diagrams were applied to decipher complex tectonic setting of W-MVB.
- •
Miocene basic rocks indicate a rift and intermediate an arc setting.
- •
Crust beneath W-MVB is highly heterogeneous as evidenced from their REE contents.
- •
Triple-rift system does effect chemistry of W-MVB rocks; the three rifts differ.
- •
Basic and intermediate magmas show petrogenetic process-related tectonic settings.
