The cartographic collection of the Doc Fisher Geoscience Library consists of the maps and air photos created or acquired by agency staff since the formation of BMR in 1946. This includes maps produced by agencies which have merged with these over the years, such as AUSLIG. Maps held include: Australian geological map series (1:250,000, 1:100,000 and the 1 mile series); topographic maps produced by NATMAP and its predecessors (1:250,000, 1:100,000 and 1:50,000) - latest editions only; various Australian geochemical, geophysical and other thematic maps; geoscience map series from other countries acquired on an exchange basis, including some with accompanying explanatory notes; Non-series maps acquired by donation or exchange; atlases. The Air photos are predominantly those used for mapping Australia and, to a lesser extent, Papua New Guinea and Antarctica, by BMR/AGSO from the 1940s to the 1980s. Geographical coverage of the sets is not complete, but many individual photos are unique in that they have pin points, overlays or other markings made by teams in the field. The Papua New Guinea photographs in the collection may, in many cases, be the only existing copies. Flight diagrams are also held for many (but not all) sets of air photos. Some other related materials, such as montages of aerial photographs (orthophotos), are also represented in the collection.

This report gives the result of a microscopic examination of a small collection of fossiliferous rocks from the glauconitic deposits at Maslin Beach and of material collected by Sir Douglas Mawson from the vicinity of Aldinga Bay. Only the micro-fauna has been investigated as the mega-fossils have been described by many palaeontologists.

Report on samples taken at intervals from 50 feet down to 1950 feet, from No. 2 bore, Neargo.

In November, 1945, the Department of Works and Housing requested that a Geological Survey be made of a section of the Upper Cotter Valley in which it is proposed to construct a dam. Four possible dam sites were examined along the Upper Cotter River between Bushrangers and Collins Creeks. This report deals with the geology of the area examined with special reference to possible dam sites. The report is also intended as a basis for future regional work in the area lying west of the Murrumbidgee River where little is known of the geological structure and stratigraphical sequence.

The situation, geology and water supply of blocks 98A and 98B are discussed in this report. A geological sketch map is included.

In response to the proposal for a new administrative building to be erected, 1/4 mile east of Parliament House, nine test pits were put down by the Department of the Interior for the purpose of examining the sub-surface conditions. Four of the pits were used for engineering tests of the bearing power of the rock foundations. The geology of the site is discussed in this report.

It is considered that the future of the Mount Bischoff field depends on the success or failure attending efforts to find additional payable ore. The problem then is to locate large tonnages of replacement ore either as extensions of known orebodies or as new orebodies. The results of the campaign outlined in this report will be of paramount importance to the maintenance and development of the field, and the campaign should be conducted energetically by diamond drilling, supplemented by underground explanatory work. The geological interpretation, objectives of the drilling, and proposed drilling campaign are outlined in this report. Three accompanying geological plans are included.

The series of samples described in this report ranges from 1050 feet down to 1372 feet and is in continuation of those reported upon on 25/7/45.

A report on the testing of bauxite deposits in the Tasmanian districts of Ouse, Launceston, Rosevale and Myalla. This report is supplementary to Mr. Owen's report (1946/2).

A visit was paid to Gidleigh Station on Saturday, January 12th. The ten bores previously put down on the property were examined. Details including depth, flow, elevation, and the results of observations made at the site, are given in this report.
