Wangaratta North South, Vic, 1996 VIMP Survey (GSV3068) (P682), magnetic line data, AWAGS levelled

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.
 These line dataset from the Wangaratta North-South merge, 1996-1997 survey were acquired in 1996 by the VIC Government, and consisted of 84782 line-kilometres of data at a line spacing between 200m and 200m, and 80m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.

Alexandra, Vic, 2000 VIMP Survey (GSV3169) (P762), radiometric line data, AWAGS levelled

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.

SI 1046 Howard Channel (HIPP) Bathymetry Acquisition (20230007S)

The Howard Channel&nbsp;bathymetry survey was acquired for the Australian Hydrographic Office (AHO) during the period 9 Aug 2023 – 13 Sep 2023. This was a contracted survey conducted for the Australian Hydrographic Office by EGS Australia as part of the Hydroscheme Industry Partnership Program. The survey area encompasses an area in Howard Channel. Bathymetry data was acquired using a Kongsberg EM2040C, and processed using CARIS HIPS and SIPS, and QIMERA processing software. The dataset was then exported as a 30m resolution, 32 bit floating point GeoTIFF grid of the survey area.
This dataset is not to be used for navigational purposes.

North Broken Hill, NSW (Corona and Fowlers Gap 1:100 000 sheet areas), airborne geophysical survey, 1995/1996, operations report

The Australian Geological Survey Organisation (AGSO) flew an airborne geophysical survey
of 47,920 line kilometres over the Corona and Fowlers Gap 1:100 000 map Sheet areas on the
Broken Hill 1:250 000 map Sheet area.
The survey was flown as part of the Broken Hill Exploration Initiative, a National Geoscience
Mapping Accord project implemented by AGSO, the New South Wales Department of
Mineral Resources and the Department of Minerals and Energy South Australia.
The survey was flown along east-west flight lines spaced mainly 100 m apart (200 m in some
areas) at a nominal altitude of 60 m above ground level. AGSO flew the survey over two
periods; from September to December 1995 and from March to April 1996.
The total magnetic intensity, gamma-ray spectrometric and digital elevation model data which
were collected during the survey, have been processed and are available for purchase, in both
digital (point located data and gridded) and map form, from the Australian Geological Survey
Organisation.

Molecular Hydrogen from Organic Sources in Geological Systems

We have recently shown that molecular hydrogen generation from organic matter occurs at high maturity levels (vitrinite reflectance 3–5%) in Lower Cretaceous shales of the Songliao Basin. To evaluate and extend these implications to a wider range of source rock types and organofacies, we report on two Paleozoic maturity suites from Australia, namely the Permian Patchawarra Formation (fluviodeltaic; Type-III; Cooper Basin) and the middle Cambrian Arthur Creek Formation (marine; Type-II; Georgina Basin), and additional mature marine source rocks from Europe and the USA.
It can be inferred from high resolution mass spectrometry that rapid growth of aromatic ring systems is the major pathway for the formation of thermogenic molecular hydrogen from all organic matter types. Extensive open system pyrolysis experiments indicate that the main generation pulse occurs in the vitrinite reflectance range 3.5–5.0%. Kinetic parameters were constructed by subtracting the hydrogen associated with hydrocarbon formation from total hydrogen in the open-system experiments via adjustment factors defined by the relative yields of CH4 and H2. A cumulative H2 potential of 20 mg/g TOC is found with maximum rates of generation that are sufficient for feeding the deep biosphere. Back of the envelope calculations indicate ∼3.5E+10 tonnes of in-place accessible H2 globally, which is an order of magnitude lower than in-place shale gas resource estimates. Regionally, inferred here for the Patchawarra Formation in the Nappamerri Trough (Cooper Basin), yields per unit rock volume resemble those of economic shale gas in the Barnett Shale, Fort Worth Basin, USA.
Organic particles are, at the SEM-scale (&gt;30 nm), barren of secondary porosity in the case of terrigenous samples at all maturity stages, but show sponge-like porosity in the investigated marine source rocks exhibiting vitrinite reflectance &gt;∼2.0%. Presence of such meso- and macropores is crucial for H2 storage in marine shales, as microporosity (&lt;2 nm) yielding sorptive storage space for H2, is usually much higher in mature terrigenous kerogens.

A palynological examination of samples from the Merino group, Victoria

Nine samples (collected by Frame-Broken Hill Pty. Ltd.) from outcrops of the Mesozoic Merino Group of south-western Victoria were examined for their spore content. Four contained sufficient spores to determine their Lower Cretaceous (? Albian) age; three were fossiliferous but lacked diagnostic species; two were barren. The determinable samples contain assemblages similar to ones in the Waarre Formation and top of the Otway Group of Port Campbell Nos. 1and 2 and Flaxman's Hill No.1.

Preliminary report on the Yenberrie uranium prospect, Northern Territory

A little torbernite, reported to be associated with cassiterite, was discovered at the Yenberrie prospect, late in 1952, by Messrs. R. Young and S. Mazlin, members of a syndicate operating a battery to treat tin ore, near Mt. Todd. The area was mapped during May 1953, on a scale of 100 feet to an inch, by D.E. Gardner and N.O. Jones. The prospect was tested for radioactivity with an Austronic ratemeter, and count rates exceeding three times the local background were obtained at four localities along the main shear zone over a length of 250 feet. Samples were obtained from shallow pits and shafts sunk at three of the four localities. A plan of the area and locality maps accompany this report.
