Geology of Canberra and its Engineering Implications

Dennis Dyer

This looks at the geological history of Canberra including the main rock types, and the subsequent structural history such as folding and faulting. The present regional drainage and topography is illustrated in relation to the underlying geology. The main rock types are identified and their engineering properties such as strength and weathering are described. The engineering implications of the features are discussed.

Dennis DyerSenior Lecturer, Canberra Institute of Technology | Engineering Geologist, ACT Geotechnical Engineers

Dennis obtained a degree in science from Sydney University in 1966, majoring in Geology. He started his career with the Snowy Mountains Hydro Electric Authority, conducting geological work associated with major engineering structures (dams, tunnels, power stations, roods) in the Snowy Mountains area, NSW and Victoria. He then worked for the Electricity Commission of New South Wales, conducting geological work associated the generation and transmission of electricity and investigation of coal mines. He moved into teaching, becoming a senior lecturer in geology at the Canberra Institute of Technology, while also moonlighting for ACT Geotechnical Engineers as their engineering geologist.
