Shark Bay Satellite-Derived Bathymetry Acquisition (20210029C)

The Shark Bay Bathymetry was derived form a time series of multispectral satellite data from the Copernicus Sentinel-2 satellite sensor, acquired between January 2017 and December 2020. This dataset was produced by the University of Western Australia to support student research projects. The dataset encompasses the Shark Bay in Western Australia. These critical geospatial data layers provide the essential environmental baseline information for the long-term monitoring and management. Mapping the shallow water zone is of importance both from an environmental and socioeconomic perspective. Bathymetry data was processed following the workflow of Lebrec et al. (2021) [https://doi.org/10.5194/essd-13-5191-2021]. This dataset is not to be used for navigational purposes. This dataset is published with the permission of the CEO, Geoscience Australia.

Preliminary Results from Marine Seismic Survey GA302 over Capel and Faust Basins

Data from 50 sonobuoys were recorded over the Capel and Faust Basins, 800 km to the east of Australia in water depths 1500-2000 m, during a 2006 seismic survey (GA302) for Geoscience Australia's Big New Oil programme. These data were interpreted and forward modelled by ray-tracing to provide an estimate of P-wave velocities in the upper sedimentary section, and hence constrain estimates of sediment thickness. Also recorded were gravity and magnetic anomaly data which, in conjunction with the very high quality seismic reflection data, provided additional constraints upon the velocity models. Typical ranges in four model layers below water were: 1.9, 2.3-3.0, 3.6-4.7, 5-5.3 km/s. Gravity models based on these results were compared to features identified on depth converted seismic reflection lines and indicate that sediment thickness at densities approximating 2.3 t/m3 may reach 5 km in several localities.

Geoscience Australia Marine Survey SS06/2006 Post-Survey Report: Natural Hydrocarbon Seepage Survey on the Central North West Shelf

The petroleum potential of the central North West Shelf, encompassing the Offshore Canning and Roebuck basins, is currently considered to be poor compared to other North West Shelf basins, due to unsuccessful exploration in the past (13 dry wells drilled during 1970-1984) and the perceived absence of a prolific source rock.

In order to improve the understanding of the petroleum prospectivity of the central North West Shelf, Geoscience Australia undertook a natural hydrocarbon seepage survey of the area. The aim of the survey was to identify any sites of natural hydrocarbon seepage, which would provide direct evidence for an active petroleum system within the sub-surface. A secondary objective was to contribute to the understanding of the modern sedimentary and oceanographic processes influencing this part of the shelf, and the nature of the benthic habitats.

This report presents a summary of the results of Geoscience Australia's RV Southern Surveyor Survey SS06/2006 on the central North West Shelf, undertaken 29 May to 22 June 2006. More than 70 Gb of geophysical and oceanographic data and 140 sediment, water and video samples were acquired during the survey.

Addressing exploration uncertainties in the southern Bonaparte Basin: enhanced stratigraphic control and post drill analysis for upper Permian plays – Extended Abstract 2022 APPEA Conference

The upper Permian to Lower Triassic sedimentary succession in the southern Bonaparte Basin represents an extensive marginal marine depositional system that hosts several gas accumulations, including the Blacktip gas field that has been in production since 2009. Development of additional identified gas resources has been hampered by reservoir heterogeneity, as highlighted by preliminary results from a post drill analyses of wells in the study area that identify reservoir effectiveness as a key exploration risk.
The sedimentary succession that extends across the Permian–Triassic stratigraphic boundary was deposited during a prolonged marine transgression and shows a transition in lithofacies from the carbonate dominated Dombey Formation to the siliciclastic dominated Tern and Penguin formations.

Recent improvements in chronostratigraphic calibration of Australian biostratigraphic schemes, spanning the late Permian and Early Triassic, inform our review of available palynological data and re-interpretation and infill sampling of well data. The results provide a better resolved, consistent and up-to-date stratigraphic scheme, allowing an improved understanding of the timing, duration, and distribution of depositional environments of the upper Permian to Lower Triassic sediments across the Petrel Sub-basin and Londonderry High.

Western Australia: Phanerozoic geology and mineral resources

Phanerozoic rocks in onshore Western Australia are primarily sedimentary. Volcanic and intrusive rocks are known from only a few areas and are mostly related to continental breakup along the northwest and western margins. The age and degree of faulting varies from basin to basin, depending on tectonic setting and period of principal activity as a depocentre, but most rocks are flat-lying to gently folded. The Southern Bonaparte, Southern Carnarvon, Canning, and Gunbarrel Basins are dominantly Palaeozoic depocentres. The Canning Basin was the dominant Ordovician depocentre, and the Southern Carnarvon Basin the dominant Permian depocentre. The Perth Basin is a polycyclic basin that was active from the upper Palaeozoic onwards, but is primarily Mesozoic. The Bremer and Eucla Basins were initiated in the Mesozoic in small local depocentres, but contain more extensive, thicker Cainozoic deposits. The age of initiation and the age of the thickest infill in each basin reflects the progressive separation of Western Australia from parts of Gondwana. In addition, transported and residual regolith blankets most of the Precambrian cratons, basins and orogenic belts.  Mineralisation in Phanerozoic rocks is primarily strata-bound. Mississippi Valley-type base metals are present in Ordovician, Devonian, and Carboniferous rocks and are commonly associated with extensional faulting and evaporite-carbonate hosts. Coal swamps were important in the Permian immediately after the Gondwana glaciation and in Jurassic fluviodeltaic complexes. Mineral sands are associated with Cainozoic strandlines and associated coastal settings, but the concentration into potential economic accumulations is only partly assessed with respect to Mesozoic sediments. Significant thicknesses of evaporites (mainly halite with lesser anhydrite) are present in Ordovician and Silurian rocks, but are overshadowed by major gypsum and halite resources in Cainozoic barred marine embayments. Diamonds are associated with lamproitic intrusives of Miocene age in the Canning Basin, but have not been extracted from Phanerozoic rocks, except near Argyle, where Cainozoic gravel placers derived from the Argyle pipe are currently mined. Iron ore is mined from pisolitic channel iron deposits in Eocene palaeo drainages in the Pilbara. Various residual weathering, lateritisation and evaporation processes have concentrated significant accumulations of bauxite, uranium, and a number of industrial minerals within Cainozoic regolith.

A note on submarine phosphorite deposits

Submarine phosphorite deposits, believed to be relatively common on the ocean floor, have been most thoroughly investigated off the coasts of California and Mexico. The conditions under which these deposits formed are believed to be applicable to most of the world's phosphorite deposits. Similar conditions may exist on the continental shelf to the south of Australia which therefore seems to be the most logical place to look for submarine phosphorite. The Californian deposits are of immense size and their economic exploitation seems to be feasible.

Clarence-Moreton Basin hydrogeological inventory

This Clarence-Moreton Basin dataset contains descriptive attribute information for the areas bounded by the relevant spatial groundwater feature in the associated Hydrogeology Index map. Descriptive topics are grouped into the following themes: Location and administration; Demographics; Physical geography; Surface water; Geology; Hydrogeology; Groundwater; Groundwater management and use; Environment; Land use and industry types; and Scientific stimulus.

The formation of the Clarence-Moreton Basin initiated during the Middle Triassic due to tectonic extension. This was followed by a prolonged period of thermal cooling and relaxation throughout the Late Triassic to the Cretaceous. Deposition of a non-marine sedimentary succession occurred during this time, with the Clarence-Moreton Basin now estimated to contain a sedimentary thickness of up to 4000 m. There were three main depositional centres within the basin, and these are known as the Cecil Plain Sub-basin, Laidley Sub-basin and Logan Sub-basin.

The Clarence-Moreton Basin sediments were originally deposited in non-marine environments by predominantly northward flowing rivers in a relatively humid climate. The sedimentary sequences are dominated by a mixed assemblage of sandstone, siltstone, mudstone, conglomerate and coal. Changing environmental conditions due to various tectonic events resulted in deposition of interbedded sequences of fluvial, paludal (swamp) and lacustrine deposits.

Within the Clarence-Moreton Basin, coal has been mined primarily from the Jurassic Walloon Coal Measures, including for the existing mines at Commodore and New Acland. However, coal deposits also occur in other units, such as the Grafton Formation, Orara Formation, Bundamba Group, Ipswich Coal Measures, and Nymboida Coal Measures.

Overlying the Clarence-Moreton Basin in various locations are Paleogene and Neogene volcanic rocks, such as the Main Range Volcanics and Lamington Volcanics. The thickness of these volcanic rocks is typically several hundred metres, although the maximum thickness of the Main Range Volcanics is about 900 m. Quaternary sediments including alluvial, colluvial and coastal deposits also occur in places above the older rocks of the Clarence-Moreton Basin.

Logan River 23 M and 135 M tidal barrage sites seismic refraction survey, Queensland 1959

The report describes the results of seismic; refraction surveys at the 2.3M and 13.5M, Logan River tidal barrage site near Beenleigh, Queensland. The maximum depth to bedrock at the 2.3M site is probably 130 ft at a point, about 350 ft from the southern bank. The maximum depth to bedrock at the 13.5M site is about 80ft, near the centre of the stream. At each site test drilling to check the seismic results is recommended, before further development is planned.

Preliminary Evaluation of the Petroleum Potential of Australia's Central Eastern Margin

Australia's east coast north of Bass Strait has been very sparsely explored for petroleum. Exploration permits have been intermittently held over the offshore Sydney Basin, including an active permit at the time of writing, and some permits were held in north Queensland waters in the 1960s and 1970s, but much of the geology of this eastern continental margin is virtually unknown. This report provides a preliminary assessment of the petroleum potential of Australia's east coast, from the border between New South Wales and Victoria in the south, to the southern boundary of the Great Barrier Reef Marine Park (GBRMP) offshore southeast Queensland in the north. Petroleum exploration is prohibited within the GBRMP, and no assessment of this area is included in the report.

Palaeozoic basement rocks covered by a veneer of Cainozoic sediments underlie a large part of the study area (Figure 1). At least four sedimentary basins also underlie the continental shelf and probably the continental slope in the case of the Sydney and Maryborough Basins. These two basins are also the best known; but the Clarence-Moreton and Nambour Basins are also known to have offshore extensions on the shelf. It is also possible but not certain that the Ipswich and Lorne Basins could have offshore components, and there is some evidence of a pre-Clarence-Moreton Basin sedimentary sequence offshore of the Coffs Harbour area. In addition to these basins, several graben and half-graben associated with Tasman Sea rifting may occur within basement dominated shelf and slope areas - two of these features are known from very limited data.

First Acreage Release in Frontier Mentelle Basin

In 2010 the Australian Government offered for the first time a large exploration block for acreage release in the frontier Mentelle Basin. This large sedimentary basin (36, 000 m2) is located about 150 km to the west of Cape Leeuwin. It lies beneath the continental slope off the Yallingup Shelf and the Naturaliste Though, a bathymetric saddle, separating the Australian margin from the Naturaliste Plateau. Water depths range from 500-1500 on the continental slope to almost 4000 m in the central part of the Naturaliste Trough. 

To enable petroleum prospectivity assessment of this frontier basin in 2008-09 Geoscience Australia acquired 2570 km of industry standard seismic, as well as gravity and magnetic data during the Southwest Margins seismic survey 310. Interpretation of the new seismic data resulted in mapping of the main structures and supersequences and led to a better undertsanding of the Mentelle Basin geology.  

Petroleum prospectivity assessment of the Mentelle Basin confirmed that the Mentelle Basin has a significant potential to become a new petroleum province.  The work undertaken by Geoscience Australia team suggests that the Mentelle Basin has at least one active petroleum system. The basin is likely to contain multiple source rock intervals associated with coals and carbonaceous shales, as well as regionally extensive reservoirs and seals within fluvial, lacustrine and marine strata. A wide range of play types have been identified in the Mentelle Basin, including faulted anticlines and highside fault blocks, sub-basalt anticlines and fault blocks, drape and forced fold plays, and a large range of stratigraphic and unconformity plays.
