Geology of the BW iron claim, Hundred of Waterhouse, Northern Territory

The B.W. Iron Claim lies in Sections 7 and 8 of the Hundred of Waterhouse, about 17 miles southwest of Batchelor. The area includes granite and a sequence of sedimentary rocks that strike northwest and are vertical or dip steeply to the south. They are overlain by a band of quartzite breccia. Costeans and pits have exposed several-thin bands of hematite and one large lens approximately 65 feet wide and 120 feet long. A shaft sunk in this lens exposed solid hematite to a depth of 21 feet, where the lens is cut off by a flat-dipping fault. No ore reserves are proved although the large lens may contain as much as 15,000 tons of hematite. Further exploration should include deepening of the shaft, drilling beneath the quartzite breccia, and costeaning some of the rubble-covered slopes to test for new hematite lenses

Summary Of Data And Results Carnarvon Basin, Western Australia Wandagee No. 1 Well Marrilla  No. 1 Well Minderoo No. 1 Well Of West Australian Petroleum Pty Limited

Wandagee No. 1 Well was located in the Carnarvon Basin, Western Australia, approximately 84 miles north-east of Carnarvon. The well was drilled by Oil Drilling and Exploration CVV.A.) Fty Limited for West Australian Petroleum pty Limited, to a total depth of 3521 feet. Drilling commenced on 25th April, 1962 and was completed on 12th June, 1962. A full programme of logging, testing, and coring was undertaken.

The well was sited on a shallow part of the Wandagee Ridge. After drilling through 26 feet of Quaternary sand, the well penetrated 556 feet of a normal Carvarvon Basin sequence of Cretaceous sediments. The Upper Devonian Gneudna Formation was encountered at 591 feet, and this was followed from 912 feet by a section ranging in age from Silurian to possible Ordovician. The well bottomed at 3521 feet in the Tumblagooda Sandstone after drilling through 861 feet of the formation.

The primary objective of the well was to investigate the stratigraphy and oil potential of the Devonian and older rocks on a shallow part of the Wandagee Ridge. Traces of gas were observed in the marine siltstone unit at the top of the Tumblagooda Sandstone (2870 to 3098 feet), but no other hydrocarbon shows were recorded. Four drillstem tests recovered only brackish to salt water, The well was completed as a water well for Wandagee Station.

The off-structure drilling operation at Wandagee No. 1 was subsidized under the Petroleum Search Subsidy Act 1959-1961, from surface to total depth.

5028 Block 3 (Northwest) Grid of Total Magnetic Intensity (TMI) with Reduction to Pole (RTP) applied.

Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data 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 5028 Block 3 (Northwest) Grid of Total Magnetic Intensity (TMI) with Reduction to Pole (RTP) applied. is a first vertical derivative of the Total Magnetic Intensity grid for the Narryer.
This grid has a cell size of  degrees (approximately 20m). The grid has units of nanoTesla per km (or nT/km). The data used to produce the TMI grid was acquired in 2024 by the WA Government, and consisted of 415090 line-kilometres of data at 100m line spacing and 50m terrain clearance. A Fast Fourier Transform (FFT) process was applied to the original grid to calculate the first vertical derivative grid.

Enhancing Marine Spatial Planning through Integrated Seabed Mapping and Science Communication

Pre-competitive geoscience information, including bathymetry compilations, seabed geomorphology and sediment stability maps and other spatial information is essential to support planning and investment decisions. Integrated, multidisciplinary datasets enhance our understanding of Australia's seabed and have wide-ranging applications across multiple ocean sectors. Bathymetric and geoscience maps are used to design surveys, identify areas suitable for offshore infrastructure, and provide important regional context for environmental impact assessments, thereby reducing investment risk and supporting evidence-based decisions consistent with government policies and regulations.&nbsp;

Geoscience Australia’s integration and digital delivery of marine data provides valuable insights into the distribution and evolution of seabed features and their associated characteristics, processes and regulatory designations. Our Australian Marine Spatial Information System (AMSIS) provides a web-based interactive mapping and decision support system that improves access to integrated government and non-government spatial layers, tools, visualizations, and data for the management of Australia’s marine jurisdiction. This robust scientific information ecosystem drives the translation of data into information and knowledge to support decision-makers

Australian Bathymetry and Topography MapServer

The Australian Bathymetry and Topography web service includes the topography of Australia and the bathymetry of the adjoining Australian Exclusive Economic Zone. The area selected does not include data from Australia's marine jurisdiction offshore from the Territory of Heard and McDonald Islands and the Australian Antarctic Territory. The 2009 bathymetry data were compiled by Geoscience Australia from multibeam and single beam data, and along with the topography (onshore) data, was derived from multiple sources. As per the 2005 grid, the 0.0025 dd resolution is only supported where direct bathymetric observations are sufficiently dense (e.g. where swath bathymetry data or digitised chart data exist) (Webster and Petkovic, 2005). In areas where no sounding data are available (in waters off the Australian shelf), the grid is based on the 2 arc minute ETOPO (Smith and Sandwell, 1997) and 1 arc minute ETOPO (Amante and Eakins, 2008) satellite derived bathymetry. The topographic data (onshore data) is based on the revised Australian 0.0025dd topography grid (Geoscience Australia, 2008), the 0.0025dd New Zealand topography grid (Geographx, 2008) and the 90m SRTM DEM (Jarvis et al, 2008).

Pattern of slow seafloor spreading (<4 mm/year) from breakup (96 Ma) to A20 (44.5 Ma) off the southern margin of Australia

Australia separated from Antarctica by continental extension between the mid-Jurassic (&gt;160 Ma) and mid-Cretaceous (96 Ma), then by slow seafloor spreading (half-rate &lt; 4.4 mm/ year) on a separation azimuth of 335Â° until A21 time (49 Ma), at an intermediate half-rate (10 mm/ year) until A20 time (44.5 Ma), and then at a fast rate (20 mm/ year) on a separation azimuth of 360o to the present.  A compilation of seafloor spreading magnetic data for the entire southern margin, including critical data collected during the cruise of the R/ V Rig Seismic in 1986, confirms the previous work except for the re-interpretation of the oldest anomalies. The phase of slow spreading is characterised by (a) jumps of the spreading ridge to Australia between 131.25Â° E and Tasmania to accommodate the southeastward offset of the line  of separation between Tasmania and Antarctica, and (b) variable azimuths of spreading isochrons within individual spreading segments, as, for example, from 090oÂ±5Â° between 129Â° and 130oE (an angle of 65Â° between separation and spreading azimuths) and 075Â° and 080Â° between 130Â° and 131.75Â°E (an almost orthogonal 80Â°). The variable azimuth of the spreading isochrons, oblique to the separation azimuth, is similar to that found in the young (&lt;5 Ma) slow spreading (half-rate 10 mm/ year) ocean basin of the Gulf of Aden, and is interpreted as the response of a slow spreading system to confinement between continental margins whose boundaries are oblique to the separation azimuth.

Mapping the ocean floor

Have you ever wondered how we know the depth of the ocean? Sonar is the main technology used investigate the location of submarine canyons, seamounts, abyssal plains and if the seafloor is sand or rock. This activity builds understanding of sonar technique and applications through a) processing and plotting provided data to discover a seafloor feature or shipwreck, and b) bouncing balls on different surfaces and analysing rebound, relating this to ground hardness then extend understanding to ‘backscatter’ in bathymetry surveys. It is suitable for middle secondary students, but could be extended for senior students of Earth science, marine science/oceanography, and physics.

Seabed Environments of the Eastern Joseph Bonaparte Gulf, Northern Australia

A seabed mapping survey over a series of carbonate banks, intervening channels and surrounding sediment plains on the Van Diemen Rise in the eastern Joseph Bonaparte Gulf was completed under a Memorandum of Understanding between Geoscience Australia and the Australian Institute of Marine Sciences. The survey obtained detailed geological (sedimentological, geochemical, geophysical) and biological data (macro-benthic and infaunal diversity, community structure) for the banks, channels and plains to establish the late-Quaternary evolution of the region and investigate relationships between the physical environment and associated biota for biodiversity prediction. The survey also permits the biodiversity of benthos of the Van Diemen Rise to be put into a biogeographic context of the Arafura-Timor Sea and wider northern Australian marine region.

Four study areas were investigated across the outer to inner shelf. Multibeam sonar data provide 100 per cent coverage of the seabed for each study area and are supplemented with geological and biological samples collected from 63 stations. In a novel approach, geochemical data collected at the stations provide an assessment of sediment and water quality for surrogacy research. Oceanographic data collected at four stations on the Van Diemen Rise will provide an understanding of the wave, tide and ocean currents as well as insights into sediment transport. A total of 1,154 square kilometres of multibeam sonar data and 340 line-km of shallow (&lt;100 mbsf) sub-bottom profiles were collected.

Pickanjinnie No. 1 bore seismic velocity survey, Queensland 1960

On 12th July 1960, a velocity survey of the Associated Australian Oilfields Pickanjinnie No. 1 bore was made by a Bureau of Mineral Resources seismic party. The bore, about 1 mile south of Pickanjinnie railway station, 20 miles east of Roma, had been drilled to a depth of 5218 ft and was surveyed to the bottom. The formations drilled were Mesozoic to a depth of 4180 ft, Permian to 4835 ft and the equivalent of the Timbury Hills Formation of unknown age to the bottom of the bore. The bore produced petroliferous gas at a rate of over 5 million cubic feet per day from three horizons near the base of the Mesozoic and within the Permian strata.

The Late Triassic molluscs, conodonts, and brachiopods of the Kuta Formation, Papua New Guinea

The Kuta Formation is mainly a limestone deposit which crops out on the flanks of the Kubor Anticline in the Central Highlands of Papua New Guinea. It has been variously regarded as Cainozoic, Permian and Permo-Triassic in age, but is now positively dated as late Norian or Rhaetian (Late Triassic) on the basic of conodonts, molluscs and brachiopods. The Kuta Formation is thus the youngest known Triassic formation in Papua New Guinea. Interpretation of the local stratigraphy is simplified by this dating. It is now apparent that the marine Triassic sedimentation in Papua New Guinea commenced no later than the Anisian (Middle Triassic) and continued, probably uninterrupted, until Rhaetian time. The fossils identified and described include the conodont Misikella posthernsteini Kozur and Mock, 1974, the ammonite Arcestes (Arcestes) cf. sundaicus, Welter, 1914, and some bivalves. The brachiopods Clavigera, Zugmeyerella, Sinucosta, Robinsonella, ?Hagabirhynchia are equally important in dating the assemblage, but will be described in detail separately. All the more closely identified fossils have a Tethyan Provincial aspect except Clavigera which was previously known only from New Zealand and New Caledonia.

The Mesozoic strata of Katherine and Fergusson River 1:250 000 sheets

Lower Cretaceous strata of the Katherine and the Fergusson River 1:250,000 Sheets were examined during the 1960 and 1961 field seasons. Field observations on lithology and palaeogeography were summarised in previous Records (Skwarko,1961a,b) and these, together with the identification of the fossils collected and their dating have provided material for conclusions expressed in the present Record. Of the thirteen assemblages of fossils collected on the Katherine-Ferguson River area, nine are marine and four consist of plant remains. They appear to range in age from Neocomian to uppermost Albian. Lower Cretaceous sediments.

Changes in ideas of age of certain beds in the Australian Tertiaries

Drastic changes in ideas of the age of some of the marine Tertiary deposits in Australia have been necessary in the last few years. The recognition of Eocene over a wide area in south-eastern Australia is the result of considerable detailed mapping of deposits in south-western Victoria and the subsequent detailed investigation of the sediments for microfaunas. The discovery of the Eocene foraminiferal genus Hantkenina at different localities in south-eastern Australia has been an important factor in bringing about the recognition of the Eocene. The discovery of Hantkenina at Bird Rock, Torquay, Victoria, the type locality for the Janjukian Stage of Victorian Tertiary stratigraphy, confirms an Eocene age for beds which had previously been placed in the Upper Oligocene or the Miocene. The type section for the "Anglesean Stage" at Anglesea, west of Torquay, which has been regarded as Oligocene, is now placed in the Middle Eocene. The beds at Anglesea stratigraphically underlie those containing Hantkenina at Torquay. At least 4,000 feet of the Middle Eocene beds have been proved in bores. In western Victoria it is quite probable that Lower Eocene to Paleocene beds exist. There is still doubt as to whether definite marine Oligocene beds exist in Australia. Certain non-marine deposits thought to be of Lower Oligocene age are now Middle Miocene. Ideas of age of the beds in the Upper Tertiary have undergone little change. The calcareous sandstones of the Adelaide Basin in South Australia are regarded as Lower Pliocene rather than Middle or Upper Pliocene of certain authors.

DISCUSSION: The elusive Cook volcano and other submarine forearc volcanoes in the Solomon Islands

Discussion: A recent paper (Ex on and Johnson, 1986) in this journal concluded that activity attributed in the past to the Cook submarine volcano, in the forearc region of the New Georgia Group of the Solomon Islands, was probably largely hydrothermal blowouts from a sea floor vent (or vents) 1300 m below sea level, rather than volcanic activity.
