Community-based Seismic Monitoring Network of Papua New Guinea

The Papua New Guinea (PNG) region has been formed within an oblique convergence zone between the north-northeasterly moving Australian plate and the Pacific plate. The region is subject to most types of tectonic activity, including active folding, faulting and volcanic eruptions and hence is arguably one of the most seismically active regions in the world. Given its high level of seismic activity, PNG would benefit from a dense monitoring network to enhance the efficiency of the earthquake emergency response operations. A program to densify the earthquake monitoring network of PNG by utilizing low-cost sensors has been developed by Geoscience Australia in collaboration with the Department of Mineral Policy and Geohazards Management in PNG. To verify the performance, trial low-cost sensors were co-located with observatory-quality instrumentation for a period of one month in Port Moresby and Rabaul observatories. The comparisons demonstrated comparable recording results across a wide seismic frequency range. Once this proved successful, the first deployments were undertaken recently, with sensors installed in the Bialla International School, Kimbe International School and the Earth Science Division of the University of PNG. Educational institutions are ideal for the installation of these sensors as they can provide guaranteed internet and electricity, allowing for continuous monitoring of earthquakes. The data acquired by these stations will feed into the existing networks for national earthquake and volcano monitoring, thus expanding the national seismic network of PNG. This work is being undertaken as part of the Australian Aid program.

Lake Eyre - dose rate grid (AWAGS)

The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of potassium (K), uranium (U) and thorium (Th). The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose. The total dose rate is due to natural sources of radiation and is computed by adding estimates of cosmic dose at ground level to the terrestrial dose. The terrestrial dose rate grid is derived as a linear combination of the filtered K, U and Th grids. A low pass filter is applied to this grid to generate the filtered total dose rate grid.
This Lake Eyre - dose rate grid (AWAGS) has a cell size of 0.0004 degrees (approximately 41m) and shows the total dose rate of the Lake Eyre Airborne Magnetic Radiometric and DEM survey, SA, 2017 survey. The data used to produce this grid was acquired in 2017 by the SA Government, and consisted of 92215 line-kilometres of data at 200m line spacing and 60m terrain clearance.

Eastern Highlands of Australia; their uplift and erosion

The Eastern Highlands form a broad arch, with similar cross sections along its length, and varying altitude of its axis. At least on the western margin in Queensland and near Sydney, most of the uplift was by warping. Mesozoic sediments preserved on the summit and flanks of the highlands prove that most of the uplift was after the Early Cretaceous in Queensland, after the mid Triassic near Sydney, and after the Triassic in Tasmania. Uplift of the highlands was most likely initiated at the time of change of the sedimentation pattern and tectonics, 95 Ma ago, as suggested by Jones and Veevers, except that uplift is thought to have started in the Jurassic in Tasmania.  Denudation rates vary with local relief. The Cainozoic average rate for Queensland and New South Wales is near 3 m.Ma-1, and for Victoria and Tasmania 5-7 m.Ma-1. Gravity studies show that the Eastern Highlands are on relatively weak lithosphere, so the denudation would have resulted in denudation isostatic rebound of the local area, and the total amount of tectonic uplift is given approximately by the smoothed altitude of the present highlands.  In general, the amount of denudation is smaller than the total amount of tectonic uplift. The timing of the tectonic uplift is not well determined, but most is earlier than mid Cainozoic, and there is evidence that possibly one third of it was during the late Cainozoic.  The early tectonic uplift is thought to be due to removal of the lower lithosphere from beneath the highlands at the time of rifting to form the Tasman and Coral Seas, leading to uplift both by crustal underplating, and by the short and long-term effects of crustal heating. Later tectonic uplift is thought to be caused by crustal underplating associated with Cainozoic basaltic volcanism.

Multielement composition of the conodont species Polygnathus xylus xylus Stauffer, 1940 and Ozarkodina brevis (Bischoff and Ziegler, 1957) from the Upper Devonian of the Canning Basin, Western Australia

More than 200 conodont clusters and 1300 discrete elements belonging to Polygnathus xylus xylus and Owrkodina brevis were recovered from a sample of the Upper Devonian Napier Formation in the Oscar Range of the Canning Basin, Western Australia. A study of them indicates that both P. xylus xylus and Q brevis had a multielement structure of 15 elements, belonging to seven element types: M (2), Sa (1), Sc (4), Sb (2), Sd (2), Pb (2), and Pa (2). The better preserved and more complete clusters of P. xylus xylus have been used as a basis, with reference to a recent find of an impression of a conodont animal, for a reconstruction of the head region, showing the position of the conodont elements. Two groups of elements with distinctly different functions are recognised.  The anterior discernens elements (M, Sa, Sc, Sb, and Sd) serve to sort particulate food matter, and the posterior contundens elements (Pb, Pa), to crush the food particles prior to their entry into the gut.
