North Coast Bitou-Longdong Geopark
A staggered layer sedimentary landscape in the nose of the northeast corner of Taiwan. The staggered layer is due to the change in the depth of the seawater when the sediments are deposited, causing the sediments in different periods to have different angles of intersection during the sedimentation. After the formation of the rock layer, the sedimentary rock layer is formed, and the layers are layered.
You can also see argillaceous sandstone layers and shale layers at the cape corner. These layers are relatively weak compared to sandstone layers, so many sandstones are often seen protruding from the surface. If you carefully observe the composition of the argillaceous sandstone, you can see many biomarked fossils, among which sand sticks are common biological drilling remains in this area.
Rock layers and joints can be seen on Bitou cape sea erosion platform. Due to the relatively weak shale layers or joints in the rock when the seawater continues to erode, the rocks is easy to be eroded and depressed. These places that are sunken on the sea erosion platform where the joints or shale formations are.
Most of the rock formations at Bitou Cape are sandstone mixed with thin layers of shale. When the shale layer is eroded, grooves are formed in the sandstone. It is easy to observe the bedding and some sedimentary structures of the rock. Therefore, on the sea erosion platform, it is quite suitable for the education of geological terrain environment.
