Tai Shek Mo, Lo Wu, Northern Territories Introduction 7. Metasedimentary Rocks – Lok Ma Chau Formation The Carboniferous rocks of Hong Kong are represented by the San Tin Group. They comprise the carbonate rocks (i.e. marble) of the Yuen Long Formation, Lower San Tin Group, and the overlying non-carbonate sedimentary rocks of the Lok Ma Chau Formation, Upper San Tin Group. Although the Yuen Long Formation is known to exhibit a uniform change upwards into the Lok Ma Chau Formation, the nature of the top of the Upper San Tin Group is not known. The carbonate rocks of the Yuen Long Formation are not exposed at the surface in Hong Kong. Consequently, they have been proved entirely by drillholes. In contrast, the Lok Ma Chau Formation is exposed over a relatively large area in the northern part of the New Territories. Two members of the Lok Ma Chau Formation can be distinguished, the lower Mai Po Member and the upper Tai Shek Mo Member. The outcrops of the Lok Ma Chau Formation are mainly confined to the area between Lok Ma Chau and Map of the route to Tai Shek Mo Man Kam To, where they form a series of low hills. Outcrops to the west of Lo Wu are located within the Closed Frontier Area, so they are not easily accessible for field inspection. The Formation is most easily seen between Chau Tau, Lok Ma Chau and Tai Shek Mo, Ho Sheung Heung, especially along the ridge extending southwards from the summit of Tai Shek Mo. These Palaeozoic metasedimentary rocks are particularly well exposed in this area, and they are easily accessible by public transport. 46
