Columnar Jointing of Manjae Island in Shinan - The columnar jointing of Manjae Island is located on Manjae Island in Heuksan-myeon, Shinan-gun, Jeollanam-do. The columnar jointing of Manjae Island was formed by rapid cooling and contraction of volcanic rock (intermediate rock, rhyolite) generated by volcanic activity, an internal activity of the Earth. The columnar jointing is exceptional in terms of grouping and scale, with diverse forms of columnar jointing distributed, and various types of columnar jointing rare in Korea are confirmed, including horizontal and radial forms.
