Eyre Peninsula, SA, 1953 (P109), magnetic line data, AWAGS levelled

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.
 These line dataset from the Eyre Peninsula, SA, 1953 survey were acquired in 1953 by the SA Government, and consisted of 9840 line-kilometres of data at 1600m line spacing and 175m 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.

Australia's Identified Mineral Resources 2001

In 2000, Australia's economic demonstrated resources (EDR) of bauxite, brown coal, copper, diamond,
magnesite, mineral sands (ilmenite, rutile, and zircon), nickel, phosphate, tantalum, uranium and
vanadium increased, while those of black coal, gold, iron ore, manganese ore and lithium decreased.
EDR of zinc, lead and silver were maintained at levels similar to those reported in 1999. The
reductions in EDR were due mainly to ongoing high levels of production; commodity prices were a
subsidiary factor.
EDR of bauxite, diamond, magnesite, nickel and tantalum increased by over 15% following reviews of
resources information that became available during the year. EDR of nickel again reached record
levels and at 20 Mt is now 45% of total identified resources for this commodity. Gold EDR decreased
by just over 1% to 4959 t. This along with the continued declining trend in net growth in non-EDR for
gold and other factors, lead AGSO - Geoscience Australia to suggest that increased exploration
expenditure is required to ensure a sustainable sector in Australia.
Australia, however, continues to rank as one of the world's leading mineral resource nations. It has
the world's largest EDR of lead, mineral sands, nickel, tantalum, uranium and zinc. In addition, its
EDR is in the top six worldwide for bauxite, black coal, brown coal, copper, cobalt, copper, gold, iron
ore, lithium, manganese ore, rare earth oxides and gem/near gem diamond.
Mineral exploration expenditure fell by 19% to $676.3 million in 1999-2000, which was marginally
higher than the low point registered in the last cyclical downturn in 1992-93. Spending for calendar
year 2000, based on the sum of ABS four-quarter figures, was down by $42.9 million to $676.4 million
- essentially the same as for 1999-2000.
Production of many mineral commodities reached record levels in 1999-2000, and overall mine
production is projected by ABARE to rise by around 8% in the five years to 2005-06. Growth in mine
output over this period is expected for nickel (55%), copper (7%), zinc (9%), bauxite and alumina (6%
and 9%) and iron ore (15%). The high level of investment activity in the minerals industry since the
early 1990s, is expected to continue to fall in coming years, according to ABARE and ABS.

What have we learnt regarding cratonic earthquakes in the fifty years since Meckering?

The 14th of October 1968 Ms 6.8 (Mw 6.58) Meckering earthquake was the first of a remarkable series of nine historical surface rupturing earthquakes to occur in the Precambrian craton of western and central Australia. Geological investigations of the ruptures, including that relating to the 26th of May 2016 Mw 6.1 Petermann Ranges earthquake, found no evidence to suggest a prior event in the geologically recent past. The handful of paleo-earthquake scarps that have been investigated in the same cratonic crust setting show evidence for limited recurrence of large events (e.g. Dumbleyung, Hyden, Roopena). Further research is required to determine if the events forming the current topography are the only events that have occurred on a given fault scarp, or if they represent only the more recent of a protracted series of events. Irrespective, these data challenge the plate margin paradigm often adopted in intraplate environments that large earthquakes recur periodically on ‘active’ faults. This raises the question of whether the models used in seismic hazard analyses to describe earthquake recurrence in intraplate cratonic regions are appropriate.

Geoscience Australia Marine Survey GA0332 (SS05/2011): Natural hydrocarbon seepage survey of the offshore northern Perth Basin - Total sediment metabolism and porewater pH and salinity of seabed sediments.

In September and October of 2011 Geoscience Australia surveyed part of the offshore northern Perth Basin in order to map potential sites of natural hydrocarbon seepage. The primary objectives of the survey were to map the spatial distribution of seepage sites and characterise the nature of the seepage at these sites (gas vs oil, macroseepage vs microseepage; palaeo vs modern day seepage) on the basis of: acoustic signatures in the water column, shallow subsurface and on the seabed; geochemical signatures in rock and sediment samples and the water column; and biological signatures on the seabed. Areas of potential natural hydrocarbon seepage that were surveyed included proven (drilled) oil and gas accumulations, a breached structure, undrilled hydrocarbon prospects, and areas with potential signatures of fluid seepage identified in seismic, satellite remote sensing and multibeam bathymetry data. Within each of these areas the survey acquired: water column measurements with the CTD; acoustic data with single- and multi-beam echosounders, sidescan sonar and sub-bottom profiler (sidescan not acquired in Area F as it was too deep in places); and sediment and biological samples with the Smith-McIntyre Grab. In addition, data were collected with a remotely operated vehicle (ROV), integrated hydrocarbon sensor array, and CO2 sensor in selected areas. Sampling with the gravity corer had limited success in many of the more shallow areas (A-E) due to the coarse sandy nature of the seabed sediments. This dataset comprises total sediment metabolism (CO2 production) and porewater pH and salinity measurments of seabed sediments.
