Benthic Foraminifera as Environmental Indicators in Torres Strait - Gulf of Papua: In Todd, B.J., and Greene, H.G., eds., Mapping the Seafloor for Habitat Characterization

Three areas in the Torres Strait-Gulf of Papua region were selected for detailed study of sediments and benthic fossil biota. These areas form a transect across the shelf from the Fly River Delta to the shelf edge, near the northern extremity of the Great Barrier Reef. The Torres Strait-Gulf of Papua shelf is a shallow, low-gradient platform, where the shelf edge occurs between 120 and 140 m depth. In the study area, where the sediments range from muddy to gravelly carbonate sands, the sediment deposition rates are low and the relict content of sediment is often high. 
The three areas show distinct differences in benthic foraminiferal assemblages as indicated by relative abundances at the order level, as well as distribution patterns of individual species; these differences are also reflected in the total microbiotic communities. Given the high relict content in the surface material across these sites, a foraminiferal preservation scale was developed to assess the extent of reworking. Taphonomic features indicate that abrasion is the main factor affecting preservation.
Despite poor preservation of the foraminiferal tests, the benthic foraminiferal species have a strong correlation to water depth, indicating that transportation pathways are short. Application of multivariate statistics to analyze the relationship between environmental attributes and the distributions of the microbiota and foraminiferal species indicates the additional importance of factors including percent carbonate mud, percent gravel, organic carbon flux, temperature, salinity and mean grain size. The benthic foraminifera produce a much stronger correlation to the environmental variables than the microbiota, indicating that these organisms can provide a detailed assessment of habitat types.

Esperance Gravity Complete Spherical Cap Bouguer 1VD Grid Geodetic

Gravity data measure 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 Esperance Gravity Complete Spherical Cap Bouguer 1VD Grid Geodetic is the first vertical derivative of the complete spherical cap Bouguer anomaly grid for the Esperance Gravity Survey 2013 (P201361). This gravity survey was acquired under the project No. 201361 for the geological survey of WA. The grid has a cell size of 0.00489 degrees (approximately 498m). A Fast Fourier Transform (FFT) process was applied to the original grid to calculate the first vertical derivative grid.  A total of 7892 gravity stations at a spacing between 1000m and 2500m were acquired to produce this grid.

Multi-sensor Analysis Ready Data (ARD) intercomparison and sensitivity analyses

Multi-decadal archives of satellite imagery and rapidly growing volumes of newly acquired Earth observation (EO) data provide the opportunity to monitor and assess changes to the Earth’s surface in a systematic way. However, many satellite data users need to invest substantial time and effort into data preparation that is typically done in desktop environments, which limits effective utilisation and subsequently the societal benefit that could be realised from the datasets. 
There is a growing trend among satellite data providers to handle more of such data preparation work and provide Analysis Ready Data (ARD) as a standard product package for EO data to make it more accessible and useful to a wider user base. ARD are satellite data that have been processed to a minimum set of requirements and organised into a form that allows immediate analysis with a minimum of additional user effort and interoperability both through time and with other datasets. Although definitive specifications for different families of ARD products are currently being developed by Committee on Earth Observation Satellites (CEOS), through the CEOS Analysis Ready Data for Land  (CARD4L) framework, the effective utilisation and interoperability of cross-provider and cross-sensor ARD products may still pose challenges. 
The interoperability between ARD products will be critical for the effective user uptake of the multiple data streams. Identifying the common set of properties required for multi-sensor interoperability and assessment of the impact of parameters used in the corrections applied to derive ARD products, are important steps in achieving interoperability between ARD products. Multiple aerosol and water vapour parameters covering a range of conditions, a range of BRDF shape parameters from typical land cover types, and different solar angle normalisations covering seasonal variations have been evaluated for their impact on the derived surface reflectance, an ARD product. The results from the sensitivity analyses will be highlighted in this paper.

Geology of the Mount Isa Inlier and environs, Queensland and Northern Territory

Geological mapping of the Mount Isa Inlier and environs by the Bureau of Mineral Resources and Geological Survey of Queensland from 1969 to 1980 resulted in the production of the 1:100 000 maps which form the basis for the accompanying 1:500 000 geological map. Three broad tectonic divisions are distinguished within the Mount Isa Inlier: the Western Fold Belt, Kalkadoon-Leichhardt Belt, and Eastern Fold Belt. These are formed of early and middle Proterozoic sedimentary and volcanic rocks many thousands of metres thick, which are assigned to four major sequences, and numerous igneous intrusions. Correlatives to the northwest are exposed within and around the younger Proterozoic South Nicholson Basin and along the Murphy Tectonic Ridge. The oldest sequence in the region, designated basement, was deformed and regionally metamorphosed, in places forming migmatite, before about 1875 Ma. The three younger sequences are cover sequence 1 (1875-1850 Ma), consisting mainly of subaerial felsic volcanics, and cover sequences 2 (mostly 1790 1760 Ma) and 3 (mostly 1680-1670 Ma), comprising felsic, and mafic volcanics and predominantly shallow-water sediments. These sequences are intruded by I-type granites isotopically dated (U-Pb zircon) at around 1860 Ma, 1840 Ma, 1820 Ma, 1800 Ma, 1720-1740 Ma, 1700 Ma, 1670 Ma, and 1500 Ma. Mafic intrusions, ranging in age from pre-1860 Ma to about 1100 Ma, form dykes, sills, and pod-like bodies, and also netveined complexes with granite. The cover sequences were mildly to strongly deformed and regionally metamorphosed up to upper amphibolite facies between about 1620 and 1550 Ma. The deformation included thrusting, faulting, and open to tight upright folding. Major displacements have taken place subsequently along faults trending between northwest and northeast. The igneous rocks are markedly bimodal in composition. Four major chemically distinctive suites of felsic volcanics are identified, the oldest of which (cover sequence 1) is cogenetic with extensive granites. Most of the mafic igneous rocks are similar in chemistry to continental tholeiites. The Mount Isa Inlier contains major deposits of copper, lead, zinc and silver, and significant deposits of gold, uranium and cobalt; it has also produced minor amounts of manganese, cadmium, bismuth, tungsten, beryl, and mica. Most copper occurs in brecciated sediment-hosted deposits within the Western Fold Belt, but there are also numerous small shear and fault-controlled vein copper deposits to the east; most of the gold production has come as a by-product from these veins. Large stratiform lead-zinc-silver ores are hosted in shales, such as at Mount Isa mine. Geochemical, geographical, sedimentological and geophysical evidence favours an intracratonic tectonic setting for the Mount Isa Inlier and environs during the early and middle Proterozoic. Since about 1500 Ma, the region has been part of an essentially stable tectonic unit.

Dolichometopid trilobites of Queensland, Northern Territory and New South Wales

This Bulletin is the result of a palaeozoological and stratigraphic study of Australian species of the trilobite family Dolichometopidae, which constitutes a substantial part of the Middle Cambrian fauna. The main result in stratigraphy is the discovery of a temporal sequence of some nine assemblages of taxa of dolichometopids constituting a scale of biostratigraphic operational units equal in value to zones and operational in geological dating of strata and faunas; and in palaeozoology-morphogenesis, morphological observations regarding the structure of the cephalon and the hitherto unsuspected diversity of the Australian dolichometopids. The material from Queensland has been studied exhaustively; the dolichometopids from the Northern Territory, however, especially from Huckitta and Lucy Creek area, are in need of purposeful collecting; the same applies to central Australia and New South Wales. Of the described forms Deiradonyx toddi comes from a collection made by the Amadeus Basin Geological Party; Fuchouia" labda was collected by Mr J. N. Casey; Fuchouia sp. novo aff. atopa by Mr M. A. Randal, and Parapoliella sp. novo by the two last named -all of this Bureau; the rest of the 1l1ateI"ial has been collected by the present author in the period 1948-1962; the whole material belongs to the Commonwealth Palaeontological Collection, whose type numbers are mar.ked by the prefix.

Lithospheric-scale controls on zinc–lead–silver deposits of the North Australian Zinc Belt: evidence from isotopic and geophysical data

The North Australian Zinc Belt is the largest zinc–lead province in the world, containing 3 of the 10 largest individual deposits known. Despite this pedigree, exploration in this province during the past two decades has not been particularly successful, yielding only one significant deposit (Teena). One of the most important aspects of exploration is to choose regions or provinces that have greatest potential for discovery. Here, we present results from zinc belts in northern Australia and North America, which highlight previously unused datasets for area selection and targeting at the craton to district scale. Lead isotope mapping using analyses of mineralised material has identified gradients in μ (238U/204Pb) that coincide closely with many major deposits. Locations of these deposits also coincide with a gradient in the depth of the lithosphere–asthenosphere boundary determined from calibrated surface wave tomography models converted to temperature. In Australia, gradients in upward-continued gravity anomalies and a step in Moho depth corresponding to a pre-existing major crustal boundary are also observed. The change from thicker to thinner lithosphere is interpreted to localise prospective basins for zinc–lead and copper–cobalt mineralisation, and to control the gradient in lead isotope and other geophysical data.
