This report describes the results of a micropalaeontological examination of two rock samples from the Kimberley district.

The area was bored and sampled in May, 1948. Bores were put down to water level, using a post-hole digger. When the sand brought up from the boreholes appeared to contain appreciable quantities of heavy minerals, it was sampled by quartering. Sample weights, volumes, and dry concentrates were determined. Percentage composition of concentrates was determined by grain counting. The estimates of the quantities and grades of heavy mineral concentrates, the quantities of overburden, and the quantities of each of the heavy minerals are tabulated in this report. Data collected in the course of the investigation has been tabulated and is appended. Accompanying locality and section plans have been included.

This report describes the results of the micropalaeontological examination of two samples from central Queensland.

Report on samples from the No. 1 bore, allotment 57. The samples described in this report were taken from the depth of 1130 to 1260 feet down and are in continuation of the series reported upon in record 1948/050.

Samples from 37 bores were submitted by the Director of Mines, Adelaide, for micropalaeontological examination. Two of these bores were put down in the plains to the north of Adelaide and the remainder in the area to the south of the city. A short account of the stratigraphic sequence and detailed descriptions of the bore samples are given in this report.

This report describes the results of a micropalaeontological examination of samples taken from a depth of 0 to 922 feet down.

This report describes the results of a micropalaeontological examination of samples taken from a depth of 0 to 250 feet.

This report describes the results of the micro-examination of seven samples taken from Fossil Beach, Mornington.

A geological investigation was carried out by the writer. The aim was to check the previous mapping of the geology, and if necessary, to assist the Magnetician in locating a suitable site for magnetic observations. Some aspects of geomorphology, and the reconnaissance survey work carried out are discussed in this report.

During the summer of 1947, an expedition was despatched to Heard Island with the object of landing a party to spend about twelve months there. Geological work was undertaken by the writer. The results of this work are recorded in this report. These results include observations on the geomorphology of the island, and a description of the xenolithic ejectamenta collected from the tuffs of Rogers Head and Rogers Head Peninsula.
