The Geotechnical Engineering Office (GEO) of the Civil Engineering and Development Department (CEDD) has recently published a web-based geological memoir of Hong Kong. The internet version of the geology of Hong Kong is based largely on two published companion volumes, The Pre-Quaternary Geology of Hong Kong and The Quaternary Geology of Hong Kong, with additional details from local area memoirs.
The structure of the web-based memoir is designed to enable the geological information to be accessed according to the level of detail required. For users interested in a general overview of the geology of Hong Kong, a table of contents on the left-hand side of the webpage allows access to specific chapters contained in the published pre-Quaternary geological memoir, with the addition of a summaries of the onshore superficial deposits extracted from the Quaternary geological memoir. Alternatively, users interested in the geology of a specific area can, by clicking the location on the geological map, obtain brief information such as the name and age of the rock formation present in that area, photographs showing typical features of that rock type, and a simplified geological map showing the distribution of that rock formation in Hong Kong. Geotechnical and geological professionals requiring more detailed information can navigate further on pages detailing the lithology, structure, depositional environment and palaeontology according to specific needs. Information on specific rock formations can also be accessed quickly using a pull down menu on the top right-hand side of the webpage.
