Global Sn Isotope Compositions of Cassiterite Identify the Magmatic-Hydrothermal Evolution of Tin Ore Systems

Published Sn isotope data along with 150 new analyses of cassiterite and four granite analyses constrain two major tin isotope fractionation steps associated with (1) separation of tin from the magma/orthomagmatic transitional environment and (2) hydrothermal activity.&nbsp;&nbsp;A distinct Sn isotope difference across deposit type, geological host rocks and time of ore deposit formation demonstrates that the difference in the mean δ124Sn value represents the operation of a unified process.&nbsp;The lower Sn isotope values present in both residual igneous rocks and pegmatite suggest that heavier Sn isotopes were extracted from the system during orthomagmatic fluid separation, likely by F ligands with Sn.&nbsp;Rayleigh distillation models this first F ligand induced fractionation. The subsequent development of the hydrothermal system is characterized by initially heavier Sn isotope composition which persists in spite of Sn isotope fractionating towards isotopically lighter Sn during hydrothermal evolution.&nbsp;

Multivariate compositional analysis of groundwater geochemistry in the Georgina Basin. New insights for sediment-hosted mineral systems

The Georgina Basin in northern Australia holds significant potential for strategic minerals, particularly zinc and phosphate, which are crucial for Australia’s economy and transition to net-zero. This study applied multivariate statistical tools to groundwater geochemistry from the basin’s regional Cambrian Limestone Aquifer to investigate the prospectivity of sediment-hosted phosphate and Zn-Pb mineral systems in the northern half of the Georgina Basin. Robust principal component analysis (rPCA) identified Mo and I- (as well as Rb and Al) as key elements associated with the variation of P in groundwater. K-means cluster analysis then mapped a subset of spatial clusters where these P relationships were evident. This investigation culminated in the creation of a new geochemical index (Phos#) for identifying hydrogeochemical anomalies likely sourced from phosphate mineralisation. Five areas were most prospective using Phos#: three near Elliott, and one in each of the Central Georgina and Undilla Sub-basins. 

The hydrogeochemistry was also valuable in detecting regional sediment-hosted Zn-Pb mineralisation. Radiogenic Pb-isotope outliers (206Pb/204Pb of 22.00 to 24.00) in the Alexandria-Wonarah Basement High and Undilla Sub-basin (which were supported by elevated Pb or Zn in groundwater), were spatially correlated with observed sulfides at the surface or in drillholes and consistent with the radiogenic Pb-isotope signature of Georgina Basin’s Joplin-type, Mississippi Valley Type Zn-Pb mineralisation. 

This regional in-depth assessment of the groundwater chemistry provides an efficient scale-reduction tool with clear targets for follow-up, and is supported by a discussion on how this multivariate, index-based approach can be translated to other sedimentary basins and/or mineralisation assemblages.

Temperate Australian quantitative spatial and temporal abundance data for rocky reef biota (biodiversity): new Tasmanian MPAs

The data is quantitative abundance of fish and megafaunal invertebrates and algal % cover derived from transect based counts at a wide range of locations across Temperate Australia. The methods are described in detail in Edgar and Barrett (1997). Primarily the data are derived from transects at 5 m depth and/or 10 m depth at each site surveyed. 

Methods were initially developed for research on temporal changes following protection in Tasmanian MPAs (Maria Is, Tinderbox, Ninepin Point, Governor Island). Further research has collected data in Tasmania, in MPA planning surveys (e.g. St Helens, Waterhouse Region, Low Head, Lillico Beach, Rocky Cape), an oil spill assessment (Low Head), and in studies and surveys in new Tasmania MPAs (Port Davey and the Kent Group).  The data represented by this record was collected in the Kent Group. In many cases the dataset involved temporal replication (year scale).

Germanium, indium, gallium and cadmium in zinc ores: a mineral system approach

Sphalerite is the main Zn ore mineral and is the primary source of Cd, Ge and In and a minor source of Ga. Owing to a shift from fossil fuel to renewable energy sources, these four minor elements have progressively become more important to the economy. Despite this, resources of Cd, Ga, Ge and In are rarely reported as these metals are not considered material to the economics of resource development. As a result, the distribution of these elements between and within deposits is poorly known, and national and international resources are largely unreported.

Following previous studies, we have compiled analytical data for Cd, Ga, Ge and In from sphalerite and used global and local ore geochemical datasets to assess geochemical controls on the concentration of these elements in Zn deposits. Our results are similar to previous studies and suggest that lower-temperature deposits are enriched in Ge whereas higher-temperature deposits are enriched in In. However, modelling of hydrothermal geochemistry indicates other factors are important in concentrating these metals. In particular, the oxidation state of the fluid (oxidised versus reduced) and the depositional mechanisms also have a strong influence in Ga, Ge and In enrichment. Reduction of oxidised fluids is particularly effective in depositing Ge, whereas cooling very effectively deposits In and, in some cases, Ge. As a consequence, some higher-temperature deposits (e.g. high sulfidation epithermal and some volcanic-hosted massive sulfide) deposits can be Ge-enriched, and some lower-temperature deposits (e.g. siliciclastic-carbonate shale-hosted deposits) can be enriched in In.

Using the existing ore geochemical data and calculated characteristic Ge/Zn and In/Zn ratios, indicative estimates have been made on the endowment of Australian Zn deposits of Ge and In. These estimates highlight the potential of the North Australian Zinc Belt for Ge and for VHMS deposits for In. Although there is a large amount of uncertainty in the estimates, they are indicative of the potential for these metals in Australia.

Wellington Park Management Agency Areas

On ground management activities within Wellington Park are conducted by City of Hobart, Glenorchy City Council and the Parks and Wildlife Service. The Wellington Park Management Agency Areas layer depicts the areas that each management agency is responsible for, as defined in the Wellington Park Management Plan 2013 (amended 2015), which can be downloaded from the Wellington Park Management Trust website. 

The City of Hobart has management control over the highest visitation areas of the Park. The Council provides a high level of management input and support, and also provides work crews based at the Bushland Operations Depot (on Huon Road). The Council also provides considerable technical and operational support to the Trust.

The Glenorchy City Council provides strategic planning and operational support, and conducts maintenance on the tracks and trails within its management area.  

The Parks and Wildlife Service through its Derwent Field Centre (located at Seven Mile Beach) manages a large part of the more remote areas of the Park. The Derwent Field Centre manages a very large area that contains many reserves, thus resources to focus on the Park are very limited.

Abundance and distribution of coastal, inshore zooplankton in the Huon Estuary and D'Entrecasteaux Channel, Tasmania: Sampling trip 08/06/2005

Mesozooplankton community composition and structure were examined throughout the D’Entrecasteaux Channel, Huon Estuary and North West Bay,  Tasmania, from November 2004 to October 2005, the data represented by this record was collected on the 08/06/2005.

The composition of the mesozooplankton community was typical of inshore, temperate marine habitats, with seasonally higher abundance in summer and autumn and lower numbers in winter and spring. Copepods were the largest contributors to total abundance across all seasons and stations, while cladocerans and appendicularians were proportionally abundant in spring and summer. The faecal pellets of these three main groups, along with those of krill and amphipods, also contributed significantly to material recovered from sediment traps. Meroplanktonic larvae of benthic animals showed short-term peaks in abundance and were often absent from the water column for long periods. Spatially, North West Bay and the Channel had a higher representation of typically marine species, including Calanus australis and Labidocera cervi, while truly estuarine species, such as the copepod Gladioferens pectinatus, were more important in the Huon Estuary.

Iron oxide copper-gold potential of Australia using a hybrid data- and knowledge-driven approach and its implications for the formation of IOCG mineral systems

Iron oxide copper–gold (IOCG) deposits are a globally significant source of copper and gold, and can also contain critical minerals required for the transition to a low-carbon economy. Given their economic and strategic importance, a national-scale assessment of the mineral potential for IOCG mineral systems in Australia has been undertaken using a hybrid data- and knowledge-driven approach. For the model, 149 mappable criteria were tested using the Kolmogorov-Smirnov test, and 14 criteria were identified to show a strong relationship with known IOCG mineralization and were retained for the model. The mineral potential model successfully predicts the location of 91.7 % of known IOCG deposits and occurrences in 8.3 % of the area, reducing the exploration search space by 91.7 %. Based on the statistical analysis, criteria related to energy sources are the most important, followed by ore depositional gradients, fluid pathways and architecture, and sources of metals, fluids and ligands.

The new national-scale model highlights several new areas of elevated prospectivity for IOCG mineral systems in under-explored regions of Australia. Based on their geological evolution, IOCG mineralization is probable in the Delamerian Orogeny, the Lamboo Province and the Tanami Orogen, possible in the Western Gawler Craton, the Hooper Province and the Musgrave Province, and unlikely in the Edmund Basin, Pilbara region and the Yilgarn Craton. This study highlights how precompetitive geoscience data can be evaluated and utilized within a geologically and statistically robust framework to produce mineral potential models with strong predictive performance.

McDills SG53-07 - AUSTopo 1:250 000 digital map

This map is part of the AUSTopo - Australian Digital Topographic Map Series. It 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 516 maps. This is the largest scale at which published topographic maps cover the entire continent. Each standard map covers an area of approximately 1.5 degrees longitude by 1 degree latitude or about 150 kilometres from east to west and at least 110 kilometres from north to south. The topographic map shows approximate coverage of the sheets. The map may contain information from surrounding map sheets to maximise utilisation of available space on the map sheet. 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.

SeaMap Tasmania towed video transects 2000-2009

The SeaMap Tasmania project undertook mapping of seafloor habitats across the nearshore Tasmanian coastline (0-40 m) - the first state to compile a statewide asssimilated benthic habitat dataset.

This initiative comprised of collating aerial photography (from archives), acoustic mapping, and conducting underwater video surveys and field-based visual observations. From this, 1:25,0000 scale habitat maps were created for shallow coastal water to within 1.5 km of the coastline (or 40 m depth, which ever was arrived at first).

This record provided access to the raw video and associated annotations from video transects, which were subsequently used as validation (ground-truthing) for habitat mapping.

A submersible digital video camera was deployed at selected locations around the Tasmanian coastline. These samples were used to verify the aerial photography and echo sounder substrate classification and obtain more detailed information on biological assemblages. Transects were undertaken from the LWM (Low water mark) to 80 metres in depth or 1.5 kms from shore. Positional information was recorded for each video drop as a series of DGPS coordinates and also as a direct overlay of the DGPS output (position, date and time) onto the video.

The role of platform facilities and subsea pipelines on connectivity of key marine fauna in the Gippsland region, south-east Australia

This desktop study has modelled the influence of habitat created by platforms (n=19) and subsea pipelines (n= 32; total length approx. 738 km) operated by Esso Australia Pty Ltd (EAPL) for population connectivity of selected marine biota. The study focused on selected Esso infrastructure and natural reef habitats across the Gippsland region of Bass Strait, south-eastern Victoria. Utiliseing biophysical models that combine estimates of 3D ocean current dynamics with information on the larval biology and behaviour of three indicator fish species and two invertebrate species present within the system. This biological-physical modelling approach estimates species-specific connectivity between natural reef habitats and offshore infrastructure. Through this, we will be able to estimate the influence infrastructure may have on population connectivity in these and other similar species.

This project also provide insights as to whether infrastructure provides a net positive or negative contribution to the overall metapopulation dynamics of these species. In addition, estimates of the relative importance of individual structures (e.g., differences between various platforms) and different structural types (e.g., platforms vs. pipelines) on population connectivity.

Fouling-release coatings enhance coral spat survival by limiting algal competition on seeding devices

This data represents a set of environmental factors related to the survival rate of coral spat deployed on seeding devices with FRC protection in an midshelf habitat. This data was collected because it allows interpretation on how these different variables differentially affect spat survival and provides significant evidence of the beneficial role of FRC protection to increase survival rates by 10% after one year of reef deployment.  Data was collected from three experimental sites at Davies Reef between December 2022 and  December 2023, using underwater surveys and desktop analyses. Data was analysed using generalised linear mixed effect model and ordination techniques in a Bayesian approach and using R software.
