Field Trip


Dr Jason Ali to leads a boat geological and geomorphological excursion to the beautiful and inaccessible northeastern coast and islands of Hong Kong.

From Ma Liu Shui,the boat first travels along the Tolo Channel, a flooded river valley that follows a major northeasterly fault line. The first stop at Lai Chi Chong, displays a wavecut platform and the opportunity to examine Jurassic sedimentary and volcanic rocks along the shoreline. After landing, we walk along the beach to a small ridge to the south of Pak Kok Chai, for an overview of the Tolo Channel area including the topography, geology and structure. On the wavecut platform we look at key aspects, including interbedded volcanic and lake sediments, dipping strata, faults, bedding and crystal tuffs.

Next the boat goes to Chek Chau (Port Island, with an optional stop) to view the dipping red sedimentary rocks that originally formed in a desert setting. The boat then visits the nearby vertical delta sediments at Bluff Head, the oldest rocks (at around 360 million years), in Hong Kong.

You have the option of joining the trip at City Hall, Central and catching our coach to Ma Liu Shui or joining the trip at Ma Liu Shui ferry pier, a short taxi ride from University Station.
