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).

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).

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).
