Introduction
The Hengchun Peninsula is the narrow southernmost segment of the Central Range that forms the southern tip
of the island of Taiwan. This peninsula is underlain mainly by Miocene rocks and capped here and there with
Plio-Pleistocene and Recent sediments. The submetamorphic Miocene argillite and slate series exposed to the
north (Lushan Formation) gradually changes into non-metamorphosed Miocene rocks toward the south, the contact
being gradational and not tectonic. These non-metamorphosed Miocene rocks are exposed over much of the
Hengchun Peninsula, and constitute the main topic of this chapter.
