An introduction to Hong Kong's geology and geomorphology

19 January, 2015 - 10:21

Having given thought to the key definitions of geology and geomorphology, it's now time to take a concise overview of the shape and geology and geomorphology of Hong Kong.


Read the very good summary and introduction that was prepared by experts from the Hong Kong Geological Survey for a recent Year Book (Hong Kong 2006). You can find it here:

If you are interested in knowing more, the GEO is located in Homantin, very near the OUHK. The GEO is part of the Civil Engineering Department. You might like to seek more or alternative information of the geomorphology of Hong Kong from the Civil Engineering Department's website.

You may like to refer to this introductory account again from time-to-time as you interact with the other readings provided in this section.

Our next reading introduces you to the landscape of Hong Kong from a more scientific point of view. The reading, from the CEDD's interactive website, focuses on Hong Kong's regional geological setting.


Hong Kong Civil Engineering and Development Department, 'The Geology of Hong Kong (Interactive Online): Regional Geological Setting'.

This excellent site provides a wealth of information about Hong Kong's landscape. You can read and explore as much of it as you wish, but for now you should definitely read the section at the URL above. Please note that it's divided into a number of subsections; you can just click on the blue subheadings, and the relevant text will appear.

As you read, I would like you to notice the following points in particular:

  1. Hong Kong's landscapes contain, on display for a walker to inspect, all the major rock types e.g.
    • volcanic
    • igneous (granitic)
    • sedimentary.
  2. The diverse geology (rock types and structure) and geomorphology (landforms) have led to the creation (evolution and development) of many different habitats. This landform diversity supports, in turn, a diverse (biodiverse) plant and animal life. This point is important. In other words, there are close links between geology, geomorphology, and biology, i.e. the interactions between physical and biotic environments. This idea is very important in environmental studies.
  3. The present landscape picture is our key to understanding the past (in geological time). Hong Kong has a strong volcanic history.
