Title: Searching for the Beaumont Children and Other Adventures in Unmarked Grave Detection

Presenter: Dr Ian Moffat

Date: Tuesday 2nd June 12:30 pm AEST

Abstract:

The reliable detection of unmarked graves is one of the most important challenges faced by community groups, industry and law enforcement agencies. Burials are ubiquitous in the archaeological and forensic record however these features are challenging to locate with conventional techniques. Geophysical methods are often used for this purpose due to their non-invasive nature and rapid site coverage however graves remain a difficult target due to their subtle response and small size. This presentation reviews a number of grave detection projects, including the search for the Beaumont Children and mapping WWII graves from the Battle of Tarawa, to discuss current best practice in this field.

How remote is remote sensing from Geophysics?

The question of remote sensing’s place in the exploration tool kit has often raised questions, if not eye brows for many geologists / geophysicists. This talk provides a brief overview of the new and available satellite/airborne sensors and archived imagery, to add to this discussion – the advantages, caveats and relevance of it in the tool box. Examples include the AEGC2019 presentation of the multi-sensor and airborne geophysics case study over the Haib Cu porphyry deposit, Namibia.

How regional geophysical data has reshaped tectonic analysis of the Australian continent

Regional aeromagnetic and gravity data is a powerful tool for tectonic analysis because it can be interpreted and modelled at different scales, and it is very effective at imaging different crustal levels.  The signal in the data can also be linked to geological features and processes, and importantly, it is amenable to structural analysis, which can be used to inform 3D geometry, kinematics, and overprinting relationships.  When combined with geological context the data can constrain tectonic settings and evolutions, and importantly provide context for mineral system analysis.  We use examples from the IOCG belts of Proterozoic Australia.  We present data from the Mount Woods Inlier in the northern Gawler Craton and interpret what is likely one of the oldest preserved metamorphic core complexes on Earth.  We then illustrate how tectonic analysis can be used to resolve complex geology of the Mount Painter Inlier in the northern Curnamona Province.

Pete Betts is a Professor in the School of Earth, Atmosphere and Environment and is the Associate Dean of Graduate Research in the Faculty of Science.  His expertise is in structural analysis of regional aeromagnetic and gravity datasets, forward modelling of gravity and magnetic data, regional tectonic and geodynamic analysis, ancient and modern tectonic synthesis.  He has a diverse portfolio of research that includes the dynamics of congested subduction, ocean initiation processes in the Red Sea, tectonic evolution of the Australian Plate, mineral system analysis, New Zealand Tectonics and geophysics of volcanoes.  He has been awarded the Geological Society of Australia Bruce Hobbs and S.W Carey medals for his contributions to Australian tectonics.  He has extensive consulting experience with the Australian and international exploration community where he predominately delivers regional geological synthesis and high-resolution aeromagnetic interpretations to target mineral deposits and reduce exploration risk.

Geophysical Characterisation for the Dredging of the Marine Industry Park, Darwin

This presentation covers the use of multiple marine geophysical methods to help characterise the geology and geotechnical challenges for preliminary design of dredged access channels to a proposed marine industry development site in Darwin Harbour. The main geophysical methods utilised to characterise the geological materials where single-channel seismic reflection and densely spaced continuous marine seismic refraction.

The 2018 Professional Scientist Remuneration Survey (conducted by Professionals Australia in conjunction with Science & Technology Australia) is currently underway and open to all science professionals.

Please take a few minutes to assist the scientific community by completing the questionnaire. All survey participants have the opportunity to enter the survey competition to win one of two $500 JB-HiFi vouchers. To enter, complete the entry form available once you complete the survey.

The answers will be aggregated to compile a major report on prevailing market rates and workplace conditions for employees in positions requiring qualifications in a branch of science.

A summary of the survey results will be available on the Professionals Australia website later in the year.

The closing date for the submission of completed survey questionnaires is the 24th of June, 2018. No identifying details are required. All responses are confidential and will be handled in accordance with Professionals Australia's privacy policy.

The survey can be completed here.

The AGC remind us that International Geoscientists Day (originating from INternational Geologists Day) is celebrated in 01 April.

Geologists Day is a professional holiday of geologists, geophysicists and geochemists. It is traditionally celebrated on the first Sunday of April. The establishment of this holiday was initiated by a group of prominent Soviet geologists headed by academician Alexander Yanshin. Following their initiative, the Geologists Day was established by decree of the Presidium of the Supreme Soviet on March 31, 1966 to commemorate the achievements of Soviet geologists after discovery of the West Siberian petroleum province.

The timing of the holiday, the first Sunday in April, was chosen because it marks the end of winter and beginning of preparation for summer field work and expeditions.

Geologists Day is traditionally celebrated in almost all geological and mining organizations of the former Soviet Union with festivities starting at the end of preceding week. With tens of thousands of geologists from the former Soviet Union working around the world, the tradition of celebrating the Geologists Day is becoming more international.

In addition to geologists, many others involved in related fields also consider this day as their professional holiday and celebrate it.
