Abstract
The composition and structure of the upper 100-150 km (lithosphere) beneath the SE
Asia is currently unknown, but is an important link in understanding the evolution of the
Earth’s crust between continental China and the plate collision region beneath Taiwan.
The Penghu Islands are made up of basaltic volcanics that contain fragments of xenoliths
of the underlying mantle. Mineral chemistry of mantle xenoliths will allow the
calculation of the geothermal gradient (increase in temperature with depth). This
geotherm is the key to providing a spatial framework to locate the depths of other mantle
rock types and so define the structure of this mantle domain.
