Abstract
The Western foreland basin in Taiwan originated through the oblique collision between the Luzon volcanic arc and the Asian passive margin. The sedimentary record, including the lithographic and petrographic studies, provide a framework to understand the evolution of foreland basin. The author collected the data from literature and combined with his studies. The result present: (1) The basin physiography changed very little from the middle Miocene (12.5 Ma) to the late Pliocene (3 Ma).
(2) The basin subsidence increased during the late Pliocene (3.5
0.5 Ma), and the basin started to become wider and deeper. (3) Since the early Pleistocene (from 2 Ma) to the present the proximal-distal facies trend is clearly reversed to the south-west. The basin today is dominated by the large sediment flux form the orogeny in the East.
