Atlas of North Pilbara Geology and Geophysics: 1:1.5 Million Scale

The early to mid Archaean Pilbara Craton is one of the best exposed and
least dismembered granite/greenstone terrane in the world, and is an excellent study
area of early earth evolution. The Pilbara Craton records successive greenstone
sequences (&gt;3515 Ma to 2950 Ma) deposited on a gneissic (tonalite-trondhjemitegranite)
crust (&lt;3650 Ma) in a series of synclinal troughs that envelope large (&gt; 100
km diameter) composite ovoid granitoid complexes (3650 Ma to 2850 Ma).
The mineral potential of the Pilbara Craton has been generally down played by
industry and the area has thus not received the intense exploration industry focus
seen in the Yilgarn Craton (especially the Neo-Archaean Eastern Goldfields) to the
south. The Pilbara Craton differs fundamentally from many other granite/greenstone
terranes in terms of its tectonic evolution and metallogenesis.

Probabilistic modelling of groundwater salinity using borehole and airborne electromagnetics (AEM) data

Groundwater is a critical resource for supporting human consumption, stock water, agricultural use, and mineral or energy extraction as well as the environment. However, the quality of groundwater varies enormously from potable to hyper-saline, particularly in the Australian context. To evaluate the suitability of a groundwater resource, the spatial distribution of salinity within an aquifer is typically estimated by measuring the electrical conductivity (EC) of groundwater samples from within boreholes. However, drilling is a logistically and economically challenging task, and hydrogeologists are usually left with a sparse set of measurements from which to infer groundwater salinity over large spatial extents.
Airborne electromagnetic (AEM) surveying is a geophysical technique for estimating the bulk electrical conductivity of the near-surface. Where AEM bulk conductivity are well correlated with groundwater salinity in aquifers, AEM is a useful tool for modelling salinity in the data sparse areas between the boreholes. We present here a probabilistic method for modelling salinity and a case study from the Keep River Plains in the Northern Territory. Co-located probabilistic AEM inversions and EC measurements on pore fluids at coincident locations were fused to calculate an empirical joint probability density function. This function allowed us to estimate salinity away from the bores by sampling the ensemble of AEM conductivities. Unlike deterministic methods that provide a single estimate of salinity, our method generates an ensemble of estimates, which can be used to quantify predictive uncertainty. The results provided by our method can feed into decision making while accounting for uncertainty, enabling remote communities to manage their land and water resources more responsibly.

MRTAS Arthur Pieman tmi 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 MRTAS Arthur Pieman tmi grid geodetic has a cell size of 0.00042 degrees (approximately 41m). The units are in nanoTesla (or nT). The data used to produce this grid was acquired in 1996 by the TAS Government, and consisted of 17093 line-kilometres of data at a line spacing between 100m and 200m, and 90m terrain clearance.

Resisting the Shake: Resources for Owners of Older Masonry Buildings

Damaging earthquakes are less frequent in Australia when compared to other weather-related events, but when they do occur close to a community they can cause major damage and injury.  This risk to property and life exists for building owners, particularly if the building is of vulnerable construction.  The good news is that your building can be retrofitted to improve its earthquake resilience within a sensible budget without compromising its heritage value.  This document seeks to show you how.  It explains the nature of earthquake risk and provides resources for building owners on how the risk can be reduced for the most vulnerable building construction type: unreinforced masonry.

Crustal architecture along seismic line 22GA-CD2 new insights from the Darling-Curnamona-Delamerian deep seismic reflection survey

Output type: Exploring for the Future Extended Abstract

Short abstract:   Crustal architecture provides first order controls on the distribution of mineral resources of an area and is best imaged by deep seismic reflection data. Here we present a first interpretation of seismic line 22GA-CD2, acquired as part of the Darling-Curnamona-Delamerian (DCD) project. Line 22GA-CD2 images the central eastern Delamerian Orogen, where basement rocks are concealed by the Murray Basin. Key findings include: (i) the crustal architecture preserves many characteristics of the early evolution of west-dipping Delamerian subduction, accretion and orogeny between ~ 515 Ma - 495 Ma. This initial configuration has been reworked and reactivated during younger orogenic events; (ii) the lower and middle crust constitutes the newly defined Barrier Seismic Province, which is also imaged in legacy seismic reflection line 05GA-TL1 and interpreted to continue northeast to the Olepoloko Fault; (iii) a similar seismic character to that of the Barrier Seismic Province has been observed in legacy seismic reflection lines in Victoria and related to a Cambrian accretionary setting and adjacent foreland; (iv) the present-day upper crustal configuration is largely the result of contractional fault reactivation, with significant vertical movements during the Kanimblan-Alice Springs Orogeny (~ 360 Ma - 340 Ma); (v) a large area of prospective rocks for mineral deposits with Cambrian arc-affiliation are accessible to exploration under shallow cover of the Murray Basin (often less than 200 m).
