Kau San Tei, Tai O, Lantau Island Introduction 3. Early and Middle Jurassic Fluvial Deposits – Tai O Formation Although volcanic and intrusive rocks are widely distributed in Hong Kong, sedimentary rocks, particularly those of Mesozoic age, are restricted in their distribution. Mesozoic sedimentary rocks are mainly exposed in the less accessible upland areas or on islands in the northeast Territories, such as Pat Sin Leng, Wang Leng, and Wong Leng. However, there are more easily accessible exposures of Mesozoic sedimentary rocks at Kau San Tei, Tai O, on Lantau Island. A well-developed succession of red and grey siltstones, sandstones and conglomerates, grouped as the Tai O Formation, can be observed at this locality. Based on fossil evidence, the Formation has been dated as Early to Middle Jurassic age. Although the rocks were originally laid down in horizontal layers, the strata have subsequently been tilted by mountain-building forces so that the beds now dip to the south at between 40 o and 80 o . The Tai O district comprises a small island located in the northwestern part of the Lantau Island, and a strip of mudflats separating it from Lantau Island proper. In the past, the mudflats were developed to create fish ponds and salt pans. Today, the small village of Tai O is a very popular tourist destination. The residents are mostly fishermen who live in houses built on stilts along the seashore with every family owning a fishing boat. 22 Fossil plants from the Tai O Formation (from Lee et al, 1997)
