GSQ Anakie Qld magnetic vd1 grid geodetic

Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data 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 GSQ Anakie Qld magnetic vd1 grid geodetic is a first vertical derivative of the Total Magnetic Intensity grid for the Anakie Qld, 1990.
This grid has a cell size of 0.00096 degrees (approximately 102m). The grid has units of nanoTesla per km (or nT/km). The data used to produce the TMI grid was acquired in 1990 by the QLD Government, and consisted of 15068 line-kilometres of data at 400m line spacing and 60m terrain clearance. A Fast Fourier Transform (FFT) process was applied to the original grid to calculate the first vertical derivative grid.

Real-time cycle slip detection and repair in multi-GNSS, multi-frequency data processing : Part 2

Cycle slip detection and repair are essential quality control steps in recovering the integer ambiguities when loss of tracking signals in GNSS precise positioning occurs. In this contribution, we present an improvement  to the previous algorithm for reliable real-time cycle slip detection and repair of the Australian Analysis Centre Software (ACS) Pre-processing and Data Editing (PDE) function. First, the traditionally used algorithm based on the quality control theory is used to detect and repair the cycle slips. Then if the cycle slips are detected but not reliably repaired, the information of subsequent epochs are used together to strengthen the model and achieve a higher cycle slip repair success-rate. With such an enhancement, the model becomes more robust to accommodate the measurement noise and the ionosphere disturbance.

Gravity Survey 79Q2 (P197956), 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 Gravity Survey 79Q2 (P197956) contains a total of 1385 point data values acquired at a spacing of 2000 metres. The data is located in SA and were acquired in 1979, under project No. 197956 for None.

Geochemistry and origin of felsic igneous rocks of the western Musgrave Block

Granulite facies country rocks of the Giles Complex in the western Musgrave Block are predominantly of felsic igneous (intrusive or extrusive) origin and were metamorphosed at about 1200 Ma. The protoliths of some Y -depleted orthogneisses may represent primary felsic crust derived by partial melting of a hornblendeÂ±garnet-bearing, but feldspar-poor, mafic source, whereas others (including syn-metamorphic orthopyroxene granites) have geochemical features (notably depletion in Sr, but not Y) more consistent with intracrustal melting.  1188Â±4 Ma and ~1060 Ma hornblende-biotite granitoids (including rapakivi varieties) south of the Hinckley Range mostly have compositions (high HFSE, LREE, and Th/U, and low Sr) consistent with relatively high-temperature partial melting of near-anhydrous granulite facies crustal rocks, at least partly caused by emplacement of mafic magmas (including the Giles Complex). Granitic basement rocks to the Bentley Supergroup in the western Musgrave Block differ from granitoids of the Hinckley Range area in including a significant proportion of Y-depleted, Sr-undepleted rocks which may represent new felsic crust. The 1078Â±5 Ma felsic Smoke Hill Volcanics of the Bentley Supergroup have compositions (high HFSE, LREE, and Ga/A1, and low mg) typical of A-type and intraplate granitoids. Like the Hinckley Range hornblende-biotite granitoids, they may have been derived by partial melting of granulite facies lower crustal rocks during emplacement of mantle-derived magma ( e.g., the associated Mummawarrawarra Basalt), or, alternatively, by fractionation of basaltic magma. However, the relatively high Nb of the felsic volcanics implies a source compositionally different from either the exposed felsic crustal rocks or mafic volcanics. The somewhat younger Nd TDM model ages (1460-1570 Ma) of the Smoke Hill Volcanics compared to granulite facies metamorphics west of the Hinckley Range (1610-1900 Ma) are consistent with derivation of the former either from a relatively young crustal underplate or directly from mantle-derived magma.

This resource contains geochemistry data for the Oceanic Shoals Commonwealth Marine Reserve (CMR) in the Timor Sea collected by Geoscience Australia during September and October 2012 on RV Solander (survey GA0339/SOL5650). This dataset comprises inorganic element data from the fine fraction (Mud: &lt;63um) of the upper ~2cm of seabed sediment. The Oceanic Shoals Commonwealth Marine Reserve survey was undertaken as an activity within the Australian Government's National Environmental Research Program Marine Biodiversity Hub and was the key component of Research Theme 4 - Regional Biodiversity Discovery to Support Marine Bioregional Plans. Hub partners involved in the survey included the Australian Institute of Marine Science, Geoscience Australia, the University of Western Australia, Museum Victoria and the Museum and Art Gallery of the Northern Territory. Data acquired during the survey included: multibeam sonar bathymetry and acoustic backscatter; sub-bottom acoustic profiles; physical samples of seabed sediments, infauna and epibenthic biota; towed underwater video and still camera observations of seabed habitats; baited video observations of demersal and pelagic fish, and; oceanographic measurements of the water column from CTD (conductivity, temperature, depth) casts and from deployment of sea surface drifters. Further information on the survey is available in the post-survey report published as Geoscience Australia Record 2013/38 (Nichol et al. 2013).

Timing and tectonic setting of sediment-hosted Pb-Zn mineralisation in Paleoproterozoic northern Australia. A review and comparison with Mississippi Valley-and Irish-type deposits

Sediment-hosted Pb-Zn mineralisation is concentrated in the post-rift, syn-inversion fraction of the north Australian Paleoproterozoic Calvert Superbasin. Hangingwall uplift paired to subsidence in the footwalls of reactivated normal faults promoted not only fluid flow but the formation of synclinal depressions where sulphate-bearing brines ponded and mixed with an overpressured metalliferous fluid expelled from deeper levels during periods of seismic and tectonic instability. Seismic instability is manifest in discontinuous bedding and development of soft-sediment deformation in ore-bearing sequences compared to their absence from inter-ore horizons. On mixing with the pre-existing brine pool, the ore-bearing fluids facilitated sulphate reduction and replacement of carbonate by sphalerite and galena in seismically disturbed sedimentary layers. Mineralisation was episodic and occurred in a foreland setting during a 10 Myr period of transpression and reverse faulting accompanying the 1650 – 1640 Ma Riversleigh Tectonic Event. Paleozoic platform sequences hosting Mississippi Valley- and Irish-type mineral deposits share many similarities, raising questions about classification schemes in which the north Australian deposits belong to a separate category of sedimentary exhalative (SEDEX) Pb-Zn mineralisation and formed under distinctly different tectonic circumstances compared to their younger counterparts. Instead, these various deposits may have a lot more in common than previously supposed and form part of a continuum.

AusArray temporary passive seismic station deployment, servicing and retrieval: Geoscience Australia standard operating procedures

Exploration and management of minerals, energy and groundwater resources requires robust constraints on subsurface geology. Over the last decade the passive seismic technique has grown in popularity as it is one of a handful of non-invasive methods of imaging the subsurface. Given regional imaging relies on comparing records of ground motion between simultaneous deployments of seismometers deployed for over a year, consistency and quality of data collection lies at the heart of this technique. Here, we summarise the standard operating procedures developed by Geoscience Australia over the last 6 years for deployment, servicing and retrieval of passive seismic arrays. Our purpose is to share our experience and thereby contribute to improving the quality of passive seismic data being acquired across Australia.

Classification, genesis and evolution of ferruginous surface grains

Studies of ferruginous surface grains (FSGs) have shed considerable light on the origin of both these enigmatic grains and on regolith evolution. This paper describes a user-friendly classification scheme, and the genesis and evolution of FSGs.  The classification system has four levels. The first is based on initial observations necessary to recognise the class of regolith material to which FSGs belong, namely lags. The second separates FSGs from other lag components, such as rock fragments and resistant mineral grains, and hence requires more detailed observation of the sampled material. The third level of classification requires petrographic and mineragraphic examination- the main textural types are homogeneous, lithorelic, pseudomorphic, vesicular, sandy, and oolitic. The fourth level of classification identifies modifying microfabrics, namely concentric, cutanic, compound, mottled, and syneresis fabrics.  FSGs are formed in three main environments: the weathering profile (mottled zone and saprolite); surfical environments (soils and sediments); and subaqueous environments (lakes and rivers). They form by four main processes: ferruginisation of a protolith (mainly in the weathering profile, but also in subaerial and subaqueous sediments); concretion in a solid medium (surficial materials and the weathering profile); accretion in subaqueous environments, (lakes and rivers); and fragmentation of existing ferruginous material.  Diagenesis of FSGs causes both textural and mineralogical changes.  Dehydration, mineralogical unmixing, dissolution, and precipitation all alter the original fabric. Replacement, dehydration, and recrystallisation change the mineralogy. Hydration of hematite to goethite also occurs in humid climates. Ions of interest to exploration geochemists may be lost during syneresis and unmixing.  Application of this classification system requires integration of microfabric studies with geomorphological mapping, regolith stratigraphy, mineralogy, and geochemical data.

Geological factors in the development of sanitary landfill sites in the Australian Capital Territory

The application of geology to waste disposal problems is important with respect to site selection, design, and management. The initial site selection should take into account soils, and geomorphological and hydrological considerations, and site investigations should be based on detailed geological mapping. The seismic refraction technique is a powerful tool for the assessment of excavation conditions for feasibility study and design, and electrical resistivity techniques are potentially useful for monitoring changes in groundwater composition as a result of pollution. Increased awareness of the need for pollution control means that hydro-geological investigations and the establishment of groundwater monitoring systems are mandatory. These factors are illustrated by three case studies in the Australian Capital Territory.
