The Geology of Hong Kong
Fletcher, C. J. N., Journal of the Geological Society
The eight papers included in this thematic set were presented at a meeting on the geology of Hong Kong held at the University of Hong Kong on 22 January 1997. The meeting reviewed the accomplishments of the Hong Kong Geological Survey and its co-workers since it was founded fifteen years ago, and coincided with the publication of the final geological memoir of the current series that describes the 1.:20 000-scale geological maps of Hong Kong. The meeting also formed part of the 20th Anniversary celebrations of the establishment of the Geotechnical Engineering Office of the Hong Kong Government. A total of 12 registrants from consultant companies, academic institutions, researchers from China, and several Government departments attended the meeting. In addition. 40 students from the newly established Department of Earth Sciences of Hong Kong University were present.
Hong Kong is one of the world's major urban communities, with a population of over six million and in common with most of eastern Asia is expanding rapidly. However, development is hindered by the rugged terrain and steep-sided islands, and engineers are tackling some of the world's largest and technically most challenging civil engineering projects. This meeting highlighted the need for systematic and accurate geological information, and the importance of understanding geological processes. It brought together geologists, geotechnical engineers and engineering geologists with the common objective to sustain the effective and safe development of Hong Kong.
The meeting was opened by the Secretary for Works, H. S. Kwong, who described the significance of the geological surveying in the development of Hong Kong and the need for the continual updating and expansion of geological databases. A. W. Malone, Principal Government Geotechnical Engineer, in his introductory address stressed the essential role of geology in foundation engineering and soil mechanics.
Fourteen papers were presented during this one day meeting. The eight papers published in this thematic set cover a broad spectrum of research: crustal structure and neotectonics (Fletcher et al., Ding & Lai); geochemistry, age and tectonic setting of the plutonic and volcanic suites (Sewell & Campbell, Davis et al., Campbell & Sewell); Quaternary marine sequences (Fyfe et al.); weathering characteristics of granite (Shaw) and landslides in volcanic rocks (Kirk et al.). These papers will also be translated into Chinese and published in `Guangdong Geology,, the journal of the Bureau of Geology and Mineral Resources of Guangdong Province. The other papers covered additional aspects of Hong Kong geology: a regional geochemical stream sediment survey; recent palaeontological studies; ductile shear zones; environments of deposition of Devonian sequences; a new seismic monitoring network; and thermoluminescence dating of alluvial and slope deposits. The posters included contributions on: seismic data from the Pearl River Delta, mechanical properties of shell sand, sedimentological control of foraminiferal distribution in the Pearl River, ground investigations at the new airport at Chek Lap Kok, rock slope engineering, sedimentation rates in Victoria Harbour, trace element concentrations in coastal sediments and geotechnical behaviour of marine deposits. In his closing remarks B. M. T. Lam, Director of Civil Engineering, concluded that many of the papers and posters presented at the meeting had a direct relevance to geotechnical investigations, and he emphasised the importance of applied geological research to meet the needs of the community.
This meeting and the publication of the new geological maps and memoirs are the culmination of work by …
