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.

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.

The geophysical test survey of this field was commenced on 5/6/45 and operations were terminated on 6/8/46 when it was considered advisable to await the results of the drilling campaign for guidance in planning the future geophysical programme. The most intense work was done on the south-east gossan area where the methods used included, electromagnetic, potential-ratio, spontaneous polarisation, magnetic and resistivity. This interim report is supplementary to a detailed report of the survey and refers in detail only to some of the results on the south-east gossan area.

Progress report on the testing campaign, commenced in May, 1945, of the bauxite deposits at Ouse, Tasmania, No. 2 Area.

This report deals with all the known bauxite deposits at Ouse including one occurrence on Cleveland Estate. This report comprises notes on the general situation, access, geology, and bauxite reserves at Ouse, along with descriptions of the individual deposits.

Two earlier reports on this subject dealt with this industry on the basis of information then available and virtually omitted from consideration the activities of the producer and consumer subsidiaries of the Colonial Sugar Refining Company. This company has now supplied detailed information, particularly on its plans for production and it is therefore necessary to review the industry afresh. The production and consumption of asbestos in Australia are discussed in this report.

The extent, structure, and thickness of the Coorabin coal measures are discussed in this report.

The series of samples described in this report are from 900 to 1536 feet down in bore No.3843, and is a continuation of that reported upon on 23/5/44.

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).

The Harold's Cross Barite Deposit lies 7.4 miles slightly north of east from Captain's Flat. Four separate deposits were noted, each occupying a minor shear or joint plane in the granite. The past production and geology of these individual deposits are discussed in this report.
