The earliest recorded geological work on the area covered by the Minilya four-mile sheet was that of Woodward (1907) who examined the country north of the Minilya River and noted the limestone on the west flank of the Giralia anticline. In 1909 A. Gibb Maitland described the Carboniferous and Permian succession in the area drained by the Gascoyne, Lyons, Minilya and Lyndon Rivers, but referred the whole sequence to the Carboniferous. Geologists of Oil Search Ltd., under D. Dale Condit, examined the Carnarvon Basin in 1932, 1934 and 1935. Raggatt (1936) described the stratigraphy of the Permian in some detail and subdivided the Cretaceous sequence. Raggatt and Fletcher (1937) examined the fauna of the Permian of the Carnarvon Basin. Teichert did detailed stratigraphic work in the Wandagee area from 1938 to 1940. Geologists of the Bureau of Mineral Resources mapped the Minilya Sheet from 1948 to 1951, using R.A.A.F. aerial photographs. The present sheet is entirely the result of the mapping of the Bureau geologists although much of the stratigraphic nomenclature is adapted from Raggatt's and Teichert's work.

This report is an account of geological and geophysical investigations of the Burrundie Radioactive Prospect, which is located three and a half miles west-south-west of Burrundie Siding on the North Australian Railway.

With the increasing number of workers engaged in the study of the foraminifera in Australia and elsewhere and with the increased amount of literature that has appeared on the subject since 1930, it is considered that a bibliography of Australian Foraminifera would be of some value. The intensive investigations undertaken in the last few years in connexion with the search for oil, with its ultimate discovery in North-West Australia in December, 1953, together with the important part played by the micropalaeontologists in this exploratory work, make it necessary for workers to have literature on foraminifera easily accessible. The present bibliography is an attempt to list all known works in which reference is made to fossil and Recent foraminifera in the Australian region up to 1954. All papers, whether they contain systematic descriptions, or refer to stratigraphy, or are of a general geological nature, are included. Consequently this bibliography is divided into two sections: A) Works containing systematic descriptions of genera, species and varieties; [and] B) Works in which lists of foraminifera and stratigraphical and general geological references are given.

On 28th September, 1954, West Australian Petroleum Pty. Ltd. forwarded a short length of core from a depth of about 3,880 feet in Cape Range Well No. 1. In hand specimen the rock is dark brownish grey in colour and is dense and tough. Fragments of wood and of a pelecypod shell are present. A micro-palaeontological examination of the rock yielded interesting information as to the age of the beds the well penetrated at this depth. This section of the rock and of the fragment of wood were cut, and portion of the rock was crushed in the hope of finding micro-fossils.

A car-borne radio-metric survey of the B-volcanic formation within the reservation surrounding the A.B.C. uranium prospect indicated 32 small areas in which the radio-activity was a little in excess of 1.5 times, and in places a little higher than twice the background count of the alluvium in the valley. Testing of each area with an Austronic P.R.M. 200 failed to reveal any sources of higher radio-activity. Most of the anomalies are due to a comparatively high background count given by exposed basalt. Four anomalies found in black or dark soil in damp portions of the valley are considered to be due to traces of radio-active elements absorbed by humus. One anomaly appeared to be due to traces of radio-active material contained in "lateritized" alluvium. The other anomalies are in alluvium, and are due either to the presence of basalt a few inches from the surface, or to traces of radio-active matter deposited from seeping ground-water. Radio-metric contouring, with a view to possible costeaning, has been recommended in a small area within exposed basalt, where counts of approximately 200 per minute were obtained. No additional work is recommended on any of the other anomalies.

In the course of geological investigation of the area included in the Katherine, Mt. Todd and Lewin Springs 1-miles sheets, carried out by J.H. Rattigan and A.B. Clark, Bureau of Mineral Resources, A.B. Clark found, in September 1953, uranium mineralization subsequently known as the A.B.C. Prospect, 11 miles north-north-east of the township of Katherine. This report is a record of the detailed investigation which followed the discovery.

Two specimens of lower Cretaceous fossils from Papua New Guinea are described in this record: (i) a Neocomian Holaster of the H. cordatus group from near Mullens Harbour, Papua; and (ii) Lamellibranchia from Wapenamanda, Western Highlands District, Territory of New Guinea.
