This Bulletin is a summary of the geological history of the Canberra City District and serves as an explanation to the accompanying geological and tectonic maps. The original text was accidentally destroyed, together with all records except the maps here presented and one showing the locations of all studied outcrops (totalling 340); the collection of fossils, except for some graptolites, is still intact. The summary for the A.N.Z.A.A.S. Handbook (Opik, 1954) was compiled from the original text and served as a basis in rewriting the present Bulletin. Because of subsequent building operations, many of the destroyed records cannot be restored. The geological map requires some comment. The map is correct insofar as the visible sequence is concerned; where the sequence is obscured by faults it reflects the author's interpretation to satisfy all the circumstantial evidence - structural, lithological, and palaeontological - so far available. The accuracy of the boundaries is not absolute: small outcrops of weathered, or even fresh, rocks (for example, calcareous mudstones) do not provide all criteria for their formational classification and, in marginal cases, have had to be classified according to the boundary already inferred, and not vice versa; some portions of the boundary between the Turner Mudstone and the Riverside Formation are so treated.
