Calvert Hills 1:250 000 topographic map

This map is part of the series that covers the whole of Australia at a scale of 1:250 000 (1cm on a map represents 2.5 km on the ground) and comprises 513 maps. This is the largest scale at which published topographic maps cover the entire continent. Each standard map covers an area of 1.5 degrees longitude by 1 degree latitude or about 150 kilometres from east to west and 110 kilometres from north to south. There are about 50 special maps in the series and these maps cover a non-standard area. Typically, where a map produced on standard sheet lines is largely ocean it is combined with its landward neighbour. These maps contain natural and constructed features including road and rail infrastructure, vegetation, hydrography, contours (interval 50m), localities and some administrative boundaries. The topographic map and data index shows coverage of the sheets. Product Specifications Coverage: The series covers the whole of Australia with 513 maps. Currency: Ranges from 1995 to 2009. 95% of maps have a reliability date of 1994 or later. Coordinates: Geographical and either AMG or MGA (post-1993) Datum: AGD66, GDA94, AHD. Projection: Universal Traverse Mercator (UTM) Medium: Paper, flat and folded copies.

Southwest Seismic Zone of Western Australia: measurement of vertical ground movements by repeat levelling and gravity surveys

This paper presents results of repeat surveys of levelling and gravity, analysed to determine areas of vertical ground movement in the Southwest Seismic Zone, 75-200 km east of Perth. Levelling surveys over parts of the earthquake zone have been made during four periods, starting in 1958. Differences between repeat levelling surveys separated by 10 or more years show areas of vertical ground movement, the areas being 20-50 km across with relative height changes of 50-100 mm amplitude. Some of the vertical ground motion is movement at the time of earthquakes, some is later rebound in the same earthquake areas, and other movement does not appear to be associated with large or small earthquakes and could be due to either elastic strain, or non-seismic faulting. Precise gravity observations at 10 km spacing were made in 1980-81 and repeated in 1983. The differences between the surveys do not show any significant gravity changes. Future studies should be set up to monitor stress, strain and earthquakes in a group of small, diverse test areas, using the global positioning system.

Warrina, Billa Kalina, 68B0 Survey (P196856), gravity point data

Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. 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 Warrina, Billa Kalina, 68B0 Survey (P196856) contains a total of 1105 point data values acquired at a spacing of 350 metres. The data is located in SA and were acquired in 1968, under project No. 196856 for None.

The secret hidden in dust: Uncovering the potential to use metabarcoding of dust for provenance determination, and the capacity to utilise existing soil reference databases

The ubiquitous nature of dust, along with localised chemical and biological signatures, makes it an ideal medium for provenance determination in a forensic context. Metabarcoding of dust can yield biological communities unique to the site of interest, similarly, geochemical and mineralogical analyses can uncover elements and minerals within dust than can be matched to a geographic location. Combining these analyses presents multiple lines of evidence as to the origin of collected dust samples. In this work, we investigated whether the time an item spent at a site collecting dust influenced the ability to assign provenance. We then integrated dust metabarcoding of bacterial and fungal communities into a framework amenable to forensic casework, (i.e., using calibrated log-likelihood ratios to predict the origin of dust samples) and assessed whether current soil metabarcoding databases could be utilised to predict dust origin. Furthermore, we tested whether both metabarcoding and geochemical/mineralogical analyses could be conducted on a single sample for situations where sampling is limited. We found both analyses could generate results capable of separating sites from a single swabbed sample and that the duration of time to accumulate dust did not impact site separation. We did find significant variation within sites at different sampling time periods, showing that bacterial and fungal community profiles vary over time and space – but not to the extent that they are non-discriminatory. We successfully modelled soil and dust samples for both bacterial and fungal diversity, developing calibrated log-likelihood ratio plots and used these to predict provenance for dust samples. We found that the temporal variation in community composition influenced our ability to predict dust provenance and recommend reference samples be collected as close to the sampling time as possible. Thus, our framework showed soil metabarcoding databases are capable of being used to predict dust provenance but the temporal variation in metabarcoded communities will need to be addressed to improve provenance estimates.&nbsp;

The Lord Howe Rise: new views of enigmatic continental ribbon breakup from multi-channel seismic reflection data

The Lord Howe Rise is a continental ribbon that rifted from eastern Gondwana during the Late Cretaceous. The processes that lead to this breakup are still not fully understood, but span from slab rollback associated with back-arc extension to a plume impinging on the lithosphere. To better understand these rifting processes, a multi-leg geophysical cruise took place March¿May 2016 onboard R/V Kairei, collecting regional and high resolution multi-channel reflection and wide-angle refraction data, multibeam bathymetry, gravity, and magnetics. This study focuses on a regional ~900 km long east-west oriented profile at 27.2°S using the bathymetry and the multi-channel seismic reflection datasets. We present time and depth migrated reflection images and interpretations to address the structure and evolution of the eastern Australian margin. This seismic profile produced a clear image of the acoustic basement and overlying sedimentary strata from the Tasman Basin in the west to the Lord Howe Platform in the east. The Tasman Basin strata are tilted at depth by small-offset normal faults that do not propagate to the seafloor. These strata onlap onto the steep western edge of the Dampier Ridge, a sediment-covered basement high that steeply rises more than 3 km above the seafloor of the Tasman Basin. The basement and strata of the ridge are more deformed than the strata in the Tasman Basin. Further east, a basement low allowed for the formation of the thick Middleton Basin. This basin is more deformed on its eastern margin where the seafloor shallows onto the Lord Howe Rise. On the Lord Howe Rise itself, syn-rift and post-rift sedimentary sequences in the Capel and Faust basins document the breakup of the margin. The seismic profile ends on the eastern flank of the Lord Howe Platform, which is both the basement and seafloor regional high. The geophysical data presented here provide new constraints for reconstructing the evolution of the eastern Australian margin.

Geochemical characterisation of iron-rich regolith materials in the Olary Block of South Australia

The Olary Block (SA), an inlier of the Palaeoproterozoic Willyama Supergroup, is a target for base-metal and gold exploration.  Overburden averaging less than 100 m thick conceals much of its northern part, where an appreciation of iron-rich regolith geochemistry is necessary for evaluating grab samples and rock chips recovered from drilling and for planning follow-up exploration. Geochemical analysis of an exploration suite, and statistical processing (optimised transformations, multivariate trimming, and simultaneous R- and Q-mode principal-components analysis) has enabled us to differentiate four types of iron-rich regolith: gossanous ironstones; banded-iron formations and replacement ironstones; pisolitic ferruginous duricrusts; and lags.  The iron-rich regolith generally contains elevated As and Ba, and low Pb. Gossanous ironstones derived from the sulphide-bearing Bimba suite are consistently anomalous in Cu, Zn, As, and in places Pb, Se, U, Mo. Co. Bi , Ba, and Au.  A diverse group, the gossanous ironstones show different associations (e.g., Zn-Ba- Pb- Mn , Cu- Zn-As- Mo- Ag- Co- Bi, Cu- As- Mo, and Zn- Cu- As). The iron formations and replacement ironstones are the least geochemically anomalous materials , except for one notable occurrence of anomalous Mn, P, As, and Zn. The pisolitic ferruginous duricrust contains Cu- Zn concentrations of 100-200+ ppm, and anomalous U, Ni, Se, and Ag compared with veneer lags.  Detritus, or lags shed from the gossans and ironstones, have a similar chemical signature to their parent material. Veneer lags of ferruginous fragments, pisoliths, and nodules locally mantle the landscape where weathering profiles are preserved, and form a homogeneous group characterised by high Ba and As.

Wangaratta North South total count 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. The terrestrial dose rate grid is derived as a linear combination of the filtered K, U and Th grids. A low pass filter is applied to this grid to generate the filtered terrestrial dose rate grid.
This Wangaratta North South total count grid geodetic has a cell size of 0.00042 degrees (approximately 42m) and shows the terrestrial dose rate of the Wangaratta North-South merge, 1996-1997. The data used to produce this grid was acquired in 1996 by the VIC Government, and consisted of 84782 line-kilometres of data at a line spacing between 200m and 400m, and 80m terrain clearance.
