Penghu is located in the Taiwan Strait and is composed of 64 basalt islands. Volcanic eruptions began in the Neogene, approximately 10.5–16.2 million years ago. The volcanoes are part of the formation of volcanoes in Nanjing and Zhangzhou in eastern mainland China. The basalt landscape in Penghu Bay is characterised by columnar joints and marine erosion landforms. Columnar joints are arranged in a variety of patterns, such as the tower-shaped columnar joints of the Yuanbei basalt island, the radial columnar joints of the Qimei basalt islands and the arc-shaped columns of Xiyu. Basalt landscapes are common on all of the islands, including features such as sea caves, sea arches and marine stacks. The Penghu basalt has been well studied. Chen Paiyuan and Li Jima have published research papers on this topic. Penghu is a famous tourist area in Taiwan, and the Penghu Geological Park has been established.
