New occurrences of phyllolepid placoderms from the Devonian of central Australia

The first well-preserved bones of phyllolepid placoderms from the Devonian of central Australia are described from the Deering Hills and Waterhouse Range in the Amadeus Basin, and are compared with fragmentary remains from the Dulcie Range in the Georgina Basin . The fossil horizon in the Deering Hills occurs in strata previously mapped as part of the Mereenie Sandstone, but which clearly belongs to the Harajica Sandstone Member of the Parke Siltstone (Pertnjara Group). At this locality in the Deering Hills the entire Harajica Sandstone and underlying Deering Siltstone Members disappear along strike against the top of the Mereenie Sandstone, indicating that the formation boundary is not a simple angular unconformity as had been previously assumed. Two phyllolepid species of uncertain generic assignment appear to be represented in the Pertnjara Group. The Waterhouse Range occurrence may be a younger fossil horizon than that in the Deering Hills. A third indeterminate genus and species occurs in the upper Dulcie Sandstone in the Georgina Basin, and is associated with remains referable to Austrophyllolepis Long, 1984 and Placolepis Ritchie, 1984. These genera are otherwise only known from Frasnian strata in southeastern Australia. A provisional zonal scheme, with a suggested age range of late Givetian to late Famennian, is proposed for phyllolepid assemblages from Australia and Antarctica. Vertebrate and micro floral horizons in the Pertnjara Group are summarised, and an illustrated spine of Wuttagoonaspis sp. from basal Pertnjara Group sediments in the western Amadeus provides further evidence of correlation with the Mulga Downs Group of western New South Wales.

Davis Coastal Seabed Mapping Survey, Antarctica (GA4301/AAS2201/HI468) - Interpreted Geomorphic Map

The Davis Coastal Seabed Mapping Survey, Antarctica (GA-4301 / AAS2201 / HI468) was conducted on the Australian Antarctic Division workboat Howard Burton during February-March 2010 as a component of Australian Antarctic Science (AAS) Project 2201 - Natural Variability and Human Induced Change on Antarctic Nearshore Marine Benthic Communities. The survey was undertaken as a collaboration between Geoscience Australia, the Australian Antarctic Division and the Australian Hydrographic Service (Royal Australian Navy). The survey acquired multibeam bathymetry and backscatter datasets from the nearshore region of the Vestfold Hills around Davis Station, Antarctica. 
This dataset comprises an interpreted geomorphic map produced for the central survey area using multibeam bathymetry and backscatter grids and their derivatives (e.g. slope, contours). Six geomorphic units; basin, valley, embayment, pediment, bedrock outcrop and scarp were identified and mapped using definitions suitable for interpretation at the local scale (nominally 1:10 000). Polygons were created using a combination of automatic extraction and manual digitisation in ArcGIS. For further information on the geomorphic mapping methods and a description of each unit, please refer to OBrien P.E., Smith J., Stark J.S., Johnstone G., Riddle M., Franklin D. (2015) Submarine geomorphology and sea floor processes along the coast of Vestfold Hills, East Antarctica, from multibeam bathymetry and video data. Antarctic Science 27:566-586.

A Schema To Categorise Residential Buildings In Australian Floodplains

Recent events in Queensland in 2011 and 2013 have highlighted the vulnerability of housing to flooding and have caused billions of dollars in losses. To reduce future losses there is a significant need for mitigating the risk posed by existing residential buildings in flood prone areas. Therefore, a project is underway within the new Bushfire and Natural Hazards Cooperative Research Centre (BNHCRC) to provide an evidence base to inform decision making on the mitigation of flood risk by providing information on the cost-effectiveness of a range of mitigation strategies.
As an initial step to assess mitigation options, after conducting a review of existing schemas, a new building schema is developed to categorise the Australian residential buildings into a limited number of typical building types for which vulnerability functions can be developed. The proposed schema divides each building into the sub-elements of foundations, bottom floor, upper floors (if any) and roof of the building to describe its vulnerability. The schema classifies each building floor based on the attributes of Construction Period, Fit-out Quality, Storey Height, Floor System, Internal Wall Material and External Wall Material.
The schema defines 60 discrete building/vulnerability classes based on the above mentioned attributes. It excludes combinations that are invalid in an Australian context. Furthermore, the schema proposes 6 roof types based on material and pitch of the roof.

Environment of deposition of the Carlo Sandstone, Georgina Basin, Queensland and Northern Territory

The Carlo Sandstone is part of the Toko Group of the Georgina Basin. This basin, which straddles the Northern Territory-Queensland border, comprises carbonate and clastic rocks of Cambrian and Early Ordovician age; the Toko Group forms the uppermost and dominantly clastic part of the sequence. The Carlo Sandstone, which is of possible Early Ordovician age (? latest Arenig), consists of very fine to fine quartzose sandstone containing siltstone and mudstone pellets. Minor siltstone and mudstone interbeds are present. The unit is conformable with the underlying Nora and overlying Mithaka Formations. Sedimentary structures present include: flute marks, current crescents, various other current lineations, ripple-marks, cross stratification, lamination and various biogenic sedimentary structures. The palaeocurrent measurements indicate uni-directional currents. Fossils are rare except in the uppermost part of the unit where gastropods, pelecypods, nautiloids, trilobites, brachiopods and fish are present. A study of geometry, lithology, sedimentary structures, palaeocurrents and fossils indicate subtidal to intertidal depositional conditions. Of various depositional models, a barrier model is favoured. The Nora Formation represents the offshore, below wave base sediments; the Carlo Sandstone the barrier, either dunes or bars; and the Mithaka Formation the lagoon-bay sediments. The sediments were deposited in an elongate epicontinental sea that also covered the Amadeus, Wiso and Canning Basins.

Towards a national information inventory of Australia's major hydrogeological regions

Australia is the driest inhabited continent on Earth, and groundwater is crucial to supporting many urban and rural communities, economic activities and environmental values. Geoscience Australia, the nation’s trusted advisor on Earth Science, is renewing a deliberate focus on national-scale hydrogeological challenges within the Exploring for the Future program. This will be accomplished by building upon Geoscience Australia’s historic legacy in groundwater studies, including the development of the 1987 national hydrogeological map. Updating the extents, data and scientific understanding of the regions depicted in this map, and bringing it into a version suitable for access and use in the 21st century, will address many limitations of the existing map and its accompanying knowledge base. This compilation of information on Australia’s major hydrogeological regions, including both geospatial analyses of national datasets and high-level summaries of scientific literature, provides for a clear and consistent synthesis of hydrogeological and related contextual information. Supporting the delivery of the National Water Initiative and National Groundwater Strategic Framework, the inventory will benefit multi-sector water users (agriculture, communities, industry and tourism) and the environment. This work will also directly assist prioritisation and decision-making for future investment, and focus groundwater research in the work programs of Geoscience Australia and potentially inform national hydrogeological research more broadly.

East Tennant whole rock inorganic geochemistry data release

As part of Geoscience Australia's Exploring for the Future program, the East Tennant region, which is centred on the Barkly Roadhouse in the Northern Territory, was identified as having favourable geological and geophysical indicators of mineral systems potential. Potentially prospective stratigraphy in the East Tennant region is completely concealed beneath Mesoproterozoic to Quaternary cover sequences. Prior to 2020 basement rocks in the East Tennant region were only known from a handful of legacy boreholes, supported by geophysical interpretation. In order to test geophysical interpretations and obtain additional samples of basement rocks for detailed analysis, a stratigraphic drilling campaign was undertaken in the East Tennant region as part of the MinEx CRC’s National Drilling Initiative. Ten stratigraphic boreholes were drilled through the cover sequences and into basement for a total of nearly 4000 m, including over 1500 m of diamond cored basement rocks to be used for scientific purposes. 
Inorganic geochemical samples from East Tennant National Drilling Initiative boreholes were taken to characterise cover and basement rocks intersected during drilling. Two sampling approaches were implemented based on the rocks intersected:
1) Borehole NDIBK04 contained localised sulphide mineralisation and elevated concentrations of several economically-significant elements in portable X-ray fluorescence data. In order to understand the geochemical variability and distribution of elements important for mineral system characterisation, the entire basement interval was sampled at nominal one metre intervals. This spacing was reduced to between 0.5 and 0.25 m from 237 m to 263 m to better understand a more intense zone of mineralisation, and
2) Samples from boreholes NDIBK01, NDIBK02, NDIBK03, NDIBK05, NDIBK06, NDIBK07, NDIBK08, NDIBK09 and NDIBK10 were selected to capture lithological and geochemical variability to establish bulk rock geochemical compositions for further interpretation. Attempts were made to sample representative, lithologically consistent intervals.
A total of 402 samples were selected for analysis. Sample preparation was completed at Geoscience Australia and Bureau Veritas, with all analyses performed by Bureau Veritas in Perth. All samples were submitted for X-ray fluorescence (XRF), laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS), FeO determination, and loss on ignition (LOI). Samples from borehole NDIBK04 also underwent total combustion C and S, and Pb collection fire assay by ICP-MS for determination of Au, Pt and Pd concentrations.
This data release presents inorganic geochemistry data acquired on rock samples from the ten East Tennant National Drilling Initiative boreholes.
