This report deals with the volcanic activity at Tuluman Volcano in St .Andrew Strait, 25 miles south of Lorengau in the Admiralty group. In the first of the three papers, which constitute the report, a description is given of the activity from June 1953, when the eruption began, to the end of July-1954. Part II describes further submarine activity in October and November 1954, and the condition of the active centres at that time. In Part III a more detailed description of the eruptive activity is given and the eruption and the associated phenomena are reviewed at some length. Volcanic activity in the St. Andrew Strait has originated from at least five, separate centres, from one of which another cone has been formed by a branching-off from the main conduit. As a result, three islands, two of which have been subsequently joined, have been built up above sea level. The name Tuluman Islands is proposed for these islands, and individual cones are numbered according to the chronological order in which they have been formed. The geographical position of the Tuluman Islands and their topography are also discussed.

This report deals with geological and geophysical investigations of the George Creek Uranium Prospect, which is 80 miles by road south of Darwin, N.T. The rocks, sandstone and siltstone, which form part of the east limb of a large north-plunging syncline, belong to the George Creek Formation of Lower Proterozoic Age. The radioactive anomaly within the 3-times-background contour covers an area of 4 acres. Torbernite is found in weak shears, joints, and bedding-plane fractures at the surface. Torbernite and uranite have been intersected by diamond drill holes. The uranium mineral intersected is below ore grade. Two more diamond drill holes have been recommended; on to test for primary uranium mineral vertically below the most highly mineralised outcrop, the other to test for an extension of uranium mineral below alluvium south-west of the most highly mineralised outcrop.

During a recent visit to Portland with Dr. N. Boutakoff and Mr. Spencer Jones of the Geological Survey of Victoria, samples were collected systematically at localities along Dutton Way which skirts the eastern shores of Portland Bay and along the foreshore below the station. Locality 2 on Dutton Way represents the type of Maritemo Formation and is approximately eight feet thick. These beds overlie the white deposits of the Portland Limestone and are overlain by basalt. The monument section shows portion of the Maritemo Beds and portion of the topmost unit of the Formation, the Werriko Beds. This section is also overlain by basalt and underlain by Portland Limestone.

This paper provides a Micropalaeontological examination of samples from Carnarvon Basin, Western Australia. Samples of six cores from this bore were forwarded for palaeontological examination by West Australian Petroleum Pty. Ltd. The fauna from each core, with notes on the age and correlation is provided in this paper.

Twelve rock samples from the Rough Range Structure were submitted by West Australian Petroleum Pty. Ltd. for micropalaeontological examination. The result of the examination of an earlier collection was given in Records 1955/48. Seven of the present samples came from a gully due east of Rough Range Well No.6 and five from a gully due east of Rough Range Well No.6 and five from a gully immediately south of Rough Range Well No.7. The distance between the two well sites is approximately 2 ¼ miles. A detailed description of samples from each section together with the thickness of the section is given below. The sections from each locality are arranged in descending stratigraphical sequence.
