Geological Field Trip to Lai Chi Chong, Port Island and Ap Chau Meeting Location : Ma Liu Shui Pier (10-15 mins walk from the MTR University Station) (see attached map) Date : 18th October 2014 (Saturday) Time : 8:50 am to 5 pm Cost : $300 (Limited to 40 persons) Includes: Hot Lunch, a 1-day CPD certificate Overview Experienced Geologist will be leading the 1-day field trip to Lai Chi Chong, Port Island and Ap Chau. Lai Chi Chong Ancient volcanic lake deposits at Lai Chi Chong, Tolo Channel, feature a kaleidoscopic pattern of colours and textures. The layers of grey sandstone, dark grey siltstone and orangish volcanic rock of the Lai Chi Chong Formation have been folded by postdepositional events (Figures 1 and 2). Figure 1 Figure 2 Port Island The Cretaceous sedimentary rocks of Hong Kong have long been recognized as comprising a continental red bed succession. A distal alluvial fan or proximal braidplain is thought to be the most likely depositional environment for the Port Island Formation. The presence of cyclicity amongst the facies indicates periodic tectonic uplift in the hinterland that supplied the detritus to the basin. Tilted, layers of red sandstone, mudstone and conglomerate form the cliffs around Port Island (Figure 3). Red conglomerate on Port Island composed of boulders, cobbles and gravel of volcanic rock, mudstone, sandstone and quartz (Figure 4). Figure 3 Figure 4 Ap Chau What looks like a mammoth beast drinking from the sea off Ap Chau, Northeast New Territories, is in fact a natural arch eroded by the sea into a rock belonging to the Kat O Formation consisting of cobbles and boulders cemented together (Figure 5).
