The REE data of the initial Early Triassic basalts from the southern part of the basin has verified the existence of the oceanic crust once in the basinal evolution. The basin developed into a foreland one in the Middle-Late Triassic, indicating that the Yangtze plate once collided with the Indo-Sinian plate along the Black River fracture zone. 关 键 词：Nanpanjiang BASIN Hercynian-Indosinian stage RIFTING peripheral FORELAND BASIN
