Introduction to Port Island
Port Island, known as Chek Chau in Chinese, is a captivating island located in the northeastern part of Hong Kong. It is part of the Tai Po District and is included in the Shipwreck Bay Country Park. The island's name, meaning "Red Island," reflects its striking reddish sedimentary rocks, which are rich in iron oxide. These unique geological formations have made Port Island a notable part of the Hong Kong UNESCO Global Geopark.
Geological Features of Port Island
Port Island is renowned for its distinctive red sedimentary rocks, which date back to the Late Cretaceous period. These rocks, part of the Port Island Formation, consist of conglomerates and sandstones formed from alluvial deposits. The reddish hue is a result of iron oxidation, which occurred in an arid climate after Hong Kong's volcanic activities ceased. The island's landscape is characterized by steep slopes, cliffs, and sea caves, showcasing the effects of erosion over millions of years.
