The Petrography Database contains 29 701 descriptions of thin sections of rock and other geological material from Australia. The location is stored with each sample along with geological descriptions, including the host stratigraphic unit and lithology. Most samples have been collected by AGSO field parties.

Later in September, 1948, the writer, accompanied by L.C. Noakes and an officer of the Department of Works and Housing, Mr. F.K. Hosking, spent part of a morning examining the rock in Mt. Mugga quarry. The object of the examination was to find whether the rock was suitable for aggregate, as the presence of pyrite had been reported some years ago. A set of representative specimens was collected, and these have been studied microscopically. The geological and petrographic characteristics of the rock specimens are described in this report.

This report is a record of field work carried out by B.H. Flinter and G.E. McInnes during January-February, 1949. The area covered extends south from Queanbeyan and Mt. Stromlo to 3 miles beyond Williamsdale and represents an easterly extension of the work carried out by W.J. Orme and H.M. Harris in 1948 (Record 1948/031). The investigation was essentially of a regional character and little detailed mapping or close examination of sediments or igneous rocks was attempted. The stratigraphy, igneous rocks, structural observations, and physiography of the area are described in this report. Accompanying geological sketch and section plans are included.

The following report contains descriptions of thin sections of 17 rocks collected from cores and outcrops in the Muswellbrook area. This report is for information of officers in the area, who have retained duplicate hand-specimens. Specimens are numbered 1 to 18, and description of one specimen collected (No. 13) is not given here. Discussion of this rock is of academic interest only, and time has prevented its incorporation in the following report.

Package comprises a digital compilation of regional mapping of Bathurst (SI5508) 1:250 000 map by AGSO and NSW Department of Mineral Resources, under NGMA from 1991 to 1996.

Cenozoic basins of the Lake Frome region in South Australia contain most of Australia's known resources of sandstone-hosted uranium mineralisation. In addition to the currently operating Beverley uranium mine, two other deposits have been approved for mining (Honeymoon, Four Mile East) and discoveries continue to be made in the region (e.g., Beverley North; Heathgate Resources, announcement September 2009). While the known resources are significant, the potential of the region for very large uranium deposits has not been well understood, in part because of limited knowledge of the regional and district scale geological controls on uranium mineralisation. The multidisciplinary study reported herein applies a 'mineral systems' approach to identify and map the principal geological controls on the location of known uranium mineralisation in the Lake Frome region. This new framework is aimed at providing a basis for refined exploration targeting of areas with potential for major undiscovered deposits, thus reducing investment risk for the exploration industry.

The world class Callie lode gold mine is one of several gold deposits located at the Dead Bullock Soak goldfield in the Northern Territory Tanami Desert, about 550km northwest of Alice Springs. Its high grade and high tonnage make it an important system to understand in terms of regional mineralising processes. The aim of this research was to elucidate the important factors contributing to the formation of such a large deposit, and what features might be important for refining exploration strategies in the region.

The following report contains descriptions of thin sections and handspecimens of 21 rocks collected from cores in the Muswellbrook area. Rocks numbered 1 to 18 inclusive have previously been described (Records 1953/79) and the following rocks are numbered 19 to 35 inclusive. Locality and depth are also given.

PETROG, AGSO's Petrography Database, is a relational computer database of petrographic data obtained from microscopic examination of thin sections of rock samples. The database is designed for petrographic descriptions of crystalline igneous and metamorphic rocks, and also for sedimentary petrography. A variety of attributes pertaining to thin sections can be recorded, as can the volume proportions of component minerals, clasts and matrix. PETROG is one of a family of field and laboratory databases that include mineral deposits, regolith, rock chemistry, geochronology, stream-sediment geochemistry, geophysical rock properties and ground spectral properties for remote sensing. All these databases rely on a central Field Database for information on geographic location, outcrops and rock samples. PETROG depends, in particular, on the Field Database's SITES and ROCKS tables, as well as a number of lookup tables of standard terms. ROCKMINSITES, a flat view of PETROG's tables combined with the SITES and ROCKS tables, allows thin-section and mineral data to be accessed from geographic information systems and plotted on maps. This guide presents an overview of PETROG's infrastructure and describes in detail the menus and screen forms used to input and view the data. In particular, the definitions of most fields in the database are given in some depth under descriptions of the screen forms - providing, in effect, a comprehensive data dictionary of the database. The database schema, with all definitions of tables, views and indexes is contained in an appendix to the guide.
