Coast between Qingqi and Nansanto

Introduction
  • The 1KM long coast is the only place in Kinmen where you can see basalt coast. The weathered basalt rock can be beautiful colors of yellow, red or brown, depending on its mineralogy.
  • Basalt is usually blackish green in color. Due to oxidation of its iron-rich minerals, it weathers to different colors (brown or rust-red) depending on its moisture content. The outer layers of the rock could be peeled off in thin sheets due to the repeated heating, cooling or mineral hydration within the rock, which is called onion-skin weathering. Basalt rock is likely to collapse. The collapsed basalt rocks may pile up and eventually create a shingle beach.
  • Under the basalt lava is the clay sandstone stratum. The clay sandstone stratum preserves a lot of fossils.
 
Attractions
  • The coast of Nansanto presents the beautiful and diverse geological landscape, where you will see the stunning scenery of columnar basalt cliff.
