Based on aerial photograph interpretation, field investigation and morphometry, the Quaternary geomorphic surfaces of the Puli Basin have been recognized. Three steps of lateritic terrace (LT), one step of fluvial terrace (FT) and one step of fluvial plain (FP) are correlated mainly according to their relative height. Deformed features in the Puli Basin are characterized by the anti-synclinal forms and lineaments including linear valleys, linear scarps, tilting surfaces, tectonic bulges and range-facing scarplets, with a NNE orientation. They have been identified from LT1 to LT3 surfaces but not from the younger surfaces (FT and FP). Among them, surface Tapinding (LT1) in the northern basin tilts to S-SE and surface Waitaping (LT1) in the southern basin flexes to east. Based on the relationship between active structures and geomorphic surfaces, the evolution of the Puli Basin since late Pleistocene is interpreted as follows: (1) According to the imbrication of gravel layers, the Peikang River flowed southwardly into the Puli Basin while the Nankang River and the Mei River drained westerly into the basin, and the Tapinding, Waitapin and Meihsi alluvial fans were formed around basin accordingly. (2) Under the effect of uplifting, the Peikang River avulsed and flowed westward and surface LT1, LT2 and LT3 around Tapinding and Waitapin formed subsequently. They have also been continuously compressed and tilted by the stress mainly from southeast. (3) Deformed surfaces have been dissected and modified since then and the modern fans and flood plains dominate the basin bottom.
