Seamounts, Canyons and Reefs of the Coral Sea Marine Park

This flythrough video highlights deep and mesophotic seabed environments within the Coral Sea Marine Park, offshore northeastern Australia. The mesophotic zone, commonly referred to as the ‘twilight zone’ represents the depth range below the brightly lit shallow waters down to the maximum depth that sunlight can penetrate for photosynthesis to occur (~ 30 to 150 meters beneath the sea surface). The featured Malay and North Flinders Reefs represent mid-ocean platform reefs and Cairns Seamount hosts a thriving coral reef community atop what is likely an extinct volcanic cone. These locations represent a range of benthic communities, which vary with depth and substrate type. Soft-sediments (sands, muds and oozes) dominate the deep seafloor, with evidence of water currents that produce bedforms showing active sediment transport at these depths. The walls and flanks of the platform reefs are very steep, with evidence of slope failure where rocky head walls have collapsed and deposited large blocks and boulders on the seafloor, which provide important habitat for sessile and mobile invertebrates including soft corals and sponges as well as cryptic octopus. 
Typical mesophotic habitats included vast Halimeda algal meadows and rhodolith beds interspersed with soft corals and sponges on soft-sediment. Hard substrates were typically colonised by plate and encrusting hard Scleractinian corals (e.g. Leptoseris and Montipora species), sponges and ascidians. Many large black corals (Antipatharia) and gorgonians (Octocorallia) also featured, with several black coral and carnivorous sponge observations representing new species. The reef community atop Cairns Seamount was highly diverse and included many demersal and pelagic fish species. A high abundance and diversity of gelatinous zooplankton were observed in the deep waters between reefs in the Coral Sea, with several new range extensions recorded.
Bathymetry data and seafloor imagery for this flythrough were collected on RV Falkor, owned and operated by the Schmidt Ocean Institute (SOI), during surveys FK200830 and FK200902 in August and October 2020. These surveys were led by Geoscience Australia and James Cook University. Collaborative research partners included the Japan Agency for Marine-Earth Science and Technology, The University of Tokyo, Queensland University of Technology, Queensland Museum, The University of Sydney, University of Tasmania and the University of Wollongong.

Mt Isa D Gravity Bouguer Anomaly geodetic

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 Mt Isa D Gravity Bouguer Anomaly geodetic is a complete Bouguer anomaly grid for the Mt Isa Area D Gravity Survey (P200643). This gravity survey was acquired under the project No. 200643 for the geological survey of QLD. The grid has a cell size of 0.0075 degrees (approximately 794m). The data are given in units of um/s^2, also known as 'gravity units', or gu. A total of 4821 gravity stations were acquired to produce this grid.

Australian Proterozoic Mineral Systems: Essential Ingredients and Mappable Criteria

Most orebodies have cross-sections of less than 1 km2 and hence do not offer a particularly large target for exploration. Fortunately, although in the geological record ore deposits are small and rare and result from the exceptional coincidence of certain geological processes, these processes are mappable on a much larger, district to regional scale and constitute a mineral system in which the ore deposit is the central feature.

North Australian Craton iron oxide-copper-gold (IOCG) mineral potential assessment: geospatial data

Following the successful outcomes of the Tennant Creek-Mt Isa (TISA) mineral potential assessment (Murr et al., 2019; Skirrow et al., 2019), the methodology has been expanded to encompass the entire North Australian Craton (NAC). Like its predecessor, this assessment uses a knowledge-based, data-rich mineral systems approach to predict the potential for iron oxide-copper-gold (IOCG) mineralisation. With their high metal yield and large alteration footprint, IOCG mineral systems remain an attractive target in directing exploration efforts towards undercover regions.
This mineral potential assessment uses a 2D GIS-based workflow to map four key mineral system components: 
(1) Sources of metals, fluids and ligands, 
(2) Energy to drive fluid flow, 
(3) Fluid flow pathways and architecture, and 
(4) Deposition mechanisms, such as redox or chemical gradients. 
For each of these key mineral system components, theoretical criteria representing important ore-forming processes were identified and translated into mappable proxies using a wide range of input datasets. Each of these criterion are weighted and combined using an established workflow to produce a models of IOCG potential. Metadata and selection rational are documented in the accompanying NAC IOCG Assessment Criteria Table.
Two scenarios were modelled for this assessment. The first is a comprehensive assessment, targeting pre-Neoproterozoic mineral systems (&gt;1500 Ma), using a combination of interpreted, geological and geophysical datasets. As geological interpretations are subjective to the geological knowledge of the interpreter, well-documented areas, such as shallow pre-Neoproterozoic basement, have a greater density of data. This increase in data density can create an inherent bias in the modelled result towards previously explored shallow terrains. The second assessment utilises only datasets which can be mapped consistently across the assessment area. As such, these are predominately based on geophysical data and are more consistent in assessing exposed and covered areas. However, far fewer criteria are included in this assessment, and observations are reflective of only the modern geological environment. Both assessments highlight existing mineral fields in WA, NT and QLD, and suggest that these regions extend under cover. Furthermore, regions not previously known for IOCG mineralisation display a high modelled potential, offering exploration prospects in previously unknown or discounted areas.
