Notes on samples of limestone collected from three caves on the Nullabor Plains, the Koonalda, the Abrakurrie, and the Weebubbie, and from the surface crust in the vicinity of the caves.

The Lakes Entrance Oil Shaft is situated in allotment 21, Parish of Colquhoun, about 2 miles north-east of Lakes Entrance township. The shaft was sunk with the object of developing, by means of low pressure mining methods, the oil-bearing beds known to exist in the lower portion of the Tertiary basin in the Lakes Entrance area. It is estimated that, during mining operations, approximately 12,000 tons of Tertiary sediments were excavated. Consequently a unique opportunity was afforded the palaeontologist and geologist to study the stratigraphic sequence of Tertiary beds in the Lakes Entrance area. During visits paid to the scene of operations, extensive collections of fossiliferous material were made by the author. This report comprises notes on the scope of the micro-palaeontological investigation, the stratigraphy and the palaeontology of the Lakes Entrance Oil Shaft.

A brief inspection was made of dolomite at two quarries near Mount Magnet on 2nd September, 1947. The report contains brief notes on the quarries and on the samples collected from these locations.

In accordance with instructions an inspection was made of the Blue Spec Mine, Nullagine, from 22nd to 27th October. A survey was made of development work since Mr. Sullivan's visit on 20th September. This entailed a survey of the 3 level drives off No. 2E. and No. 2W. winzes and the new cross-cut from the main shaft at No. 3 level. The new shaft and cross-cut on M.L. 266 were mapped and the lode was sampled and assay results obtained. The water supply problem was investigated and a site chosen for a new domestic supply bore. Three accompanying plans are included.

Notes on a small collection of opalized shells, bone fragment and specimen of precious opal from White Cliffs.

Palaeontological note on a rock sample from a bore which was sunk a few feet into a mud island, west of Pelican Point, Lake Victoria, Gippsland.

Report on a preliminary micropalaeontological examination of the samples, submitted by the Frome - Broken Hill Co. Pty. Ltd., on November 3rd, 1947, from the Northern Flinders Range area. The examination was made with a view to giving assistance to the reconnaissance work now in progress.

The report is the result of a five weeks survey of radio-active occurrences in the Marble Bar District. The principal deposits of alluvial monazite were checked and two new radio-active occurrences in granitic rocks were reported. Accompanying plans of the Marble Bar and Wodgina areas are included.

Bauxite deposits in the vicinity of Gelliondale were investigated. The report comprises notes on the locality, geology, volume, and nature of the bauxite deposits.

An area of about 190 acres lying within the boundaries of Allotment 26D, Budgeree, County of Buln Buln was taken up for prospecting purposes on 21st May, 1947. The topography, general geology of the area, and the occurrence, volume and grade of the bauxite bodies, are discussed in this report. Three accompanying plans are included.
