Five West Sea islands administrated by Korea are home to unique geological formations created one billion years ago.<br />These islands are in the limelight as candidates for national geoparks.<br />Park Se-young has more. <br /> This rock formation named 'Dumujin' on Baekryongdo Island is a result of sandy sediments being heated and pressured a billion years ago.<br />The island is also home to basaltic rocks, …which have weathered and turned yellow due to their high magnesium content.<br />The Kongdol seashore is covered by round pebbles, formed by the break-down of quartzite in the soil.<br /> Sagot Beach was once used as a natural airstrip due to the hardness of the sand.<br />And Socheongdo Island, where Korea's oldest fossils have been found, is home to the Bunbawi Rock, named for its white, chalky color.<br />The different layers and wave patterns of rocks at Nongyeo Beach provide a window back through one billion years of history.<br />The Seopungbaji Rock in Daecheongdo Island was named as such because it blocks the wind that blows from China to the West Sea.<br /><br />"Baekryongdo, Daecheongdo and Socheongdo islands are not widely known for their rich geological heritage. We will work towards sustainable development by getting them certified as national geoparks in July."<br /><br /> Ten sights on the five islands will also apply to become UNESCO Global Geopark sites.<br />Park Se-young, Arirang News. <br />
