The stratigraphic sequence of old land surfaces in northern Queensland

In northern Queensland there are several old land surfaces which are related to previous periods of erosional and depositional activity. The surfaces are of two main types - buried and exhumed unconformity surfaces formed during periods of active erosion and deposition; and terminal planation surfaces of both erosional and depositional origin which formed as stability returned at the end of each cycle of erosional activity. These terminal surfaces have generally been deeply weathered or duricrusted. The oldest landforms are exhumed unconformity surfaces of Cambrian and Mesozoic age which formed the base of the Georgina and Carpentaria Basins respectively. Three sets of unconformity and terminal surfaces are related to cycles of activity within the Cainozoic Karumba Basin. They have been correlated with surfaces elsewhere in Queensland and the Northern Territory. There are also subsidiary depositional surfaces of the current cycle, and a suite of arid landforms which has previously been treated as a surface.

GSNSW Southeast Lachlan Thorium Grid Geodetic

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.
This radiometric thorium grid has a cell size of 0.0005 degrees (approximately 50m) and shows thorium element concentration of the Southeast Lachlan, NSW, 2010 in units of parts per million (or ppm). The data used to produce this grid was acquired in 2010 by the NSW Government, and consisted of 108251 line-kilometres of data at a line spacing between 250m and 500m, and 60m terrain clearance.

Earthquake Epicentres in Australia 1841-2000 1:10m

Australia is not on the edge of a tectonic plate so why do we have earthquakes? The Indian-Australian plate is being pushed north and is colliding with the Eurasian, Philippine and Pacific plates. This causes stresses to build up in the interior of the plate which is released during earthquakes.

McArthur Basin, Northern Territory: mapping of deep troughs using gravity and magnetic anomalies

Published models for the Proterozoic McArthur Basin show up to 4 km of sedimentary cover over widespread shelves, and a 50-80 km wide by 600 km long, central meridional half-graben, the Batten Trough, in which up to 10 km of cover is preserved. This model is supported and extended herein by basin-wide interpretation of gravity and magnetic anomalies. The margins of the area of thick cover correlate with steep gravity and/or magnetic anomaly gradients. The dominant rock types in this cover are identified from their combined gravity and magnetic signatures. Estimates of depth to magnetic basement are combined with geological constraints to map the basement configuration throughout the basin. The predicted form of the Batten Trough is essentially confirmed, and concealed extensions outlined beneath the Gulf of Carpentaria. However, it is now shown that this trough is separated into two distinct structures by the Urapunga Tectonic Ridge, and it is now redefined as the Batten Trough (south only) and Walker Trough (north). The concealed Beetaloo Sub-basin of thick Roper Group, in the southwest, and possible adjacent troughs of McArthur Group carbonates, represent the subsurface link between the McArthur Basin and Tomkinson Creek beds. An east-west extension model, related to block rotation and accommodation by northwest transfer faults, is invoked to explain the evolution of the several rifts in the basin. Later deformation has modified these structures and reversed many of the earlier displacements.

Seabed environments and shallow geology of the Vlaming sub-basin, Western Australia: Chlorophyll a, b and c of seabed sediments.

Geoscience Australia undertook a marine survey of the Vlaming Sub-basin in March and April 2012 to provide seabed and shallow geological information to support an assessment of the CO2 storage potential of this sedimentary basin. The survey was undertaken under the Australian Government's National CO2 Infrastructure Plan (NCIP) to help identify sites suitable for the long term storage of CO2 within reasonable distances of major sources of CO2 emissions. The Vlaming Sub-basin is located offshore from Perth, Western Australia, and was previously identified by the Carbon Storage Taskforce (2009) as potentially highly suitable for CO2 storage. The principal aim of the Vlaming Sub-basin marine survey (GA survey number GA334) was to look for evidence of any past or current gas or fluid seepage at the seabed, and to determine whether these features are related to structures (e.g. faults) in the Vlaming Sub-basin that may extend up to the seabed. The survey also mapped seabed habitats and biota in the areas of interest to provide information on communities and biophysical features that may be associated with seepage. This research addresses key questions on the potential for containment of CO2 in the Early Cretaceous Gage Sandstone (the basin's proposed CO2 storage unit) and the regional integrity of the South Perth Shale (the seal unit that overlies the Gage Sandstone).
This dataset comprises chlorophyll a, b and c from seabed sediments (0-0.5cm).

Lower Cretaceous arenaceous foraminifera of Australia

Arenaceous Foraminifera dominate the foraminiferal assemblages in the Lower Cretaceous sediments of Australia. The majority of species described in this Bulletin come from surface and subsurface sections within the Queensland part of the Great Artesian Basin, and their occurrences, for the most part, are referred to stratigraphical formations in the Basin. In addition, species have been described from samples from northern New South Wales and parts of South Australia and Western Australia. Well-known Lower Cretaceous megafossils give a clue to the stratigraphical position of many of the samples from which the foraminifera have been obtained. Seventy-five species of arenaceous foraminifera are discussed; they belong to twenty-six genera. Twenty-three new species are described, eight of which belong to the genus Ammobaculites. Many of the arenaceous forms show a close relationship with species described from the Lower Cretaceous deposits of northern Alaska, western Canada, and parts of the United States of America.
