  • 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.

  • The monthly vulcanological report for January, 1955, from Kieta contained details of an increase in the size of one of the thermal areas in the vicinity of Lake Loloru. The writer left Rabaul with assistant Leslie Topue on 23rd February for Kieta, and reached Lake Loloru, accompanied by Cadet Patrol Officer B. O'Farrell, on 28th. After spending two days in the area, the party returned to Kieat, due to weather and transport issues, the writer and his assistant were not able to return to Rabaul until 15 March. The first report of volcanic activity in this area was given by Father W.P. Fingleton, and an aerial inspection was conducted in May 1951 by G.A. Taylor who stated in a report, dated 17/5/51, to the Government Secretary: These areas showed no evidence of recent extensions or rises of temperature. There were no indications of recent explosive activity. (reported earlier by Father Fingleton.) Reports of patrols to Lake Loloru, dated 18/5/51 and 27/5/51 by Cadet Patrol Officer B.B. Butcher and Patrol Officer A.K Jackson respectively, had conclusions similar to those in Taylor's report, although Jackson suggested that volcanic activity had increased slightly. The area was visited during June 1951 by J.G. Best, whose report (6/7/51) concluded: In the light of existing conditions it is considered that this volcano is in a dormant state, also that the possibility of an imminent eruption is remote. However, it must be borne in mind that this area is a potential danger point, and if an eruption should occur it is likely to be of the Pelean type."

  • In an unpublished report Taylor (1955) suggested that both tectonic earthquakes and volcanic activity are related to prevailing conditions of regional stress. The diagnostic value of this relationship lies in the fact that abnormal stress conditions make their presence known first by tectonic earthquakes and later by volcanic eruption. This theory was developed as a result of intensive research following upon study of the new Hebrides volcanic arc and recent volcanism. Bougainville Island, with a deep trough (Planet Deep) situated west of and orientated parallel to its line of volcanoes, exhibits a similar structural pattern to the New Mebride4s Islands and it was considered by Taylor that the relationship between tectonic earthquakes and volcanic eruptions might also apply here. As a possible means of diagnosis an analysis of earthquakes and volcanic activity in the Bougainville area was undertaken to discover whether a positive relationship existed fro Mt. Bagana, and if so, whether there were indications of impending eruption of the Lake Loloru Crater.

  • In July, 1949, the Bureau of Mineral Resources, Geology and Geophysics began an investigation of the geology and mineral resources of the Harts Range Region, Central Australia, an area of about 2,000 square miles between Latitudes 23° 00' south and 23° 30' south, and Longitudes 12:3° 45' east and 135° 30' east. The undertaking was prompted by the discovery of small amounts of radioactive minerals in pegmatites in the eastern portion of the range. It was soon realized that the deposits of radioactive minerals were not of economic size, and the investigation was therefore extended to other mineral deposits, and in particular to the mica deposits of the Harts Range and Plenty River.he Harts Range and Plenty River Mica Field is the most. Important in Australia, and had yielded 859.49 tons of commercial muscovite .valued at £692,794 to the end of 1952. The investigation of the field was carried out in field seasons between July, 1949, and October, 1951. The mica-bearing pegmatites occur in the rocks of the Harts Range Group, a complex of metamorphosed igneous and sedimentary rocks probably of Archaeozoic age.
