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.
