Hybrid cross shore and longshore shoreline evolution modeling for probabilistic assessment of beach erosion

Winds, waves and tides associated with storms are capable of causing severe damage to coastal property and infrastructure. Locations that are prone to erosion and inundation first require an accurate assessment of risk before deciding the most cost effective mitigation option. This research aims to produce probabilistic assessments of the coastal erosion and inundation risks associated with storms, particularly for coincident or clustered events, thereby helping to strengthen the resilience of coastal communities.
Coastal erosion and inundation hazard is modelled in this study by simulations of realistic storm condition forcing (waves and tides) through a morphodynamic model to calculate return periods for maximum extent of shoreline retreat and storm demand. This approach of estimating erosion return periods is superior to the assumption that the most energetic storm causes maximum erosion. The methodology is demonstrated at Old Bar, NSW and the metropolitan Adelaide beaches, SA, which are both currently erosion hotspots in Australia. These sites were selected to test the methodology for a span of geographic conditions in terms of storm climate and deep-water wave exposure, working towards developing this method into a transportable framework applicable to other coastal areas.
Desktop and field assessments of each site were conducted to document geomorphic and sediment characteristics to inform shoreline modelling. Having established the historical framework at each location, multivariate statistical analysis of wave (buoy or hindcast models) and tides for peak storm events has allowed for the synthesis of realistic future conditions. This complex sequencing of cycling between accretion and erosion incorporating cross-shore and alongshore sediment transport has been estimated using a probabilistic shoreline evolution model. Here, model outputs for both sites are illustrated and used to access risk to infrastructure based on the most probable envelope of the shoreline.

D'Aguilar Range, Tas, 2001 (WTRMP Area E) (P821), radiometric line data, AWAGS levelled

The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of potassium (K), uranium (U) and thorium (Th). 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 D'Aguilar Range, Tas, 2001 (WTRMP Area E) (P821), radiometric line data, AWAGS levelled were acquired in 2001 by the TAS Government, and consisted of 1175 line-kilometres of data at 200m line spacing and 80m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.

Uranium content of igneous rocks of Australia Map 3 Average abundance: solid geology

Igneous rocks have long been recognised as an important source of metals in uranium mineral systems. Although magmas may form mineral deposits in their own right, they may also contribute directly to basin-related mineral systems as a source of metals and/or ligands. Thus, mapping of the distribution of uranium in igneous rocks has the potential to highlight potentially prospective regions for uranium mineralisation at a macro-scale.
Map 3 in the series of three maps of the uranium content of Australian igneous rocks shows the interpreted solid geology distribution of igneous rocks. Since no nationally seamless solid geology map yet exists, datasets have been compiled from a variety of State and Territory open file sources. Polygons are coloured by their average uranium content. The average uranium content of each polygon was calculated by plotting the igneous polygons together with geochemical sample points (distribution shown in Map 1 of the series) using ArcGIS software. Each polygon was then attributed with the average uranium value (in ppm) of all intersecting geochemical sample points.
This approach allows igneous uranium content to be assessed on the pluton- to province-scale, depending on polygon resolution. Furthermore, the use of solid geology datasets allows for the uranium content of igneous rocks in the subsurface to be assessed, opening up broader areas for new potential uranium mineral systems. Together with the two other maps in the series, this map demonstrates the close spatial relationship between uranium-rich igneous rocks and areas of known uranium mineralisation. In addition, new regions previously unknown for uranium mineralisation can be identified.

Spatio-temporal evolution of Australian lithosphere–asthenosphere boundary from mafic volcanism

Cratonic margins host many of the natural resources upon which our society depends. Despite this, little is known about the dynamic evolution of these regions and the stability of substantial steps in plate thickness that delineate their boundaries with adjacent mantle. Here, we investigate the spatio-temporal evolution of Australian cratonic lithosphere and underlying asthenospheric mantle by using the geochemical composition of mafic volcanic or shallow intrusive rocks preserved throughout the continent’s history. We have collated a large database of mafic samples that were screened to remove data affected by crystal fractionation or assimilation of cumulate material. We use forward and inverse modelling of igneous trace element compositions to calculate the depth and extent of melting for 28 distinct igneous provinces in the North Australian Craton. These results are used to infer mantle potential temperature and lithospheric thickness at the time of eruption. The majority of Paleoproterozoic magmatic events record high mantle potential temperatures of 1350–1450 °C and relatively low lithospheric thicknesses of ≤50 km. In contrast, younger igneous provinces show a gradual decrease in potential temperature and an increase in lithospheric thickness with time. These constraints on the mantle lay the foundation for the development of a quantitative geodynamic understanding of the evolution of the Australian lithosphere and its resources.

Report on Giralia-Bullara seismic reflection traverse, Western Australia

This report covers the results of a seismic reflection traverse on a portion of the Giralia anticline which has been mapped in Mesozoic and Tertiary rocks in the North-West basin. The work constitutes a part of a general programme of investigation which the Bureau of Mineral Resources, Geology and Geophysics, has been carrying out on Permit areas held by Ampol Petroleum Ltd. in this area. The seismic traverse described herein lies along the main road joining Giralia and Bullara homesteads and crosses the northern end of the Giralia structure. Tests were made with shooting in shot holes and also by air shooting. In addition, a refraction spread was shot along the axis of the anticline. This report gives an account of this investigation. Technical matters, such as interpretation technique and the symbols used in plotting results, are briefly noted. The results of the study and subsequent conclusions are discussed.
