文摘

The early Paleozoic potassic and ultrapotassic rocks in SCB formed at 445–424 Ma. The group 1 and 3 were generated by the partial metling of enriched mantle source. The group 2 originated from the partial melting of their depleted mantle source. These rocks constrained the geodynamic transition time from orogen to post-orogen.
