Introduction to Organic Groundwater Geochemistry

The Australasian Land and Groundwater Association is running this course throughout Australia and in New Zealand during November.  

This is an introductory organic geochemistry course for scientists and engineers working in the field of groundwater site characterization, contamination, and remediation. It is designed to provide basic information on organic contaminants and their fate/transport in aquifer geochemical environments.

Geochemical processes that will be described and discussed include solution/gas interactions leading to volatilization and dissolution of volatile organic compounds, adsorption/desorption of organics, natural attenuation along the groundwater flowpath, and biodegradation processes. Data collection, presentation, and interpretation of results will be discussed. Examples that illustrate the concepts are described throughout the class.

At the end of this one-day class, attendees will ave a better understanding of the types of geochemical processes that affect organic contaminants, the importance of collecting sufficient data to understand site-specific geochemical systems, and the effectiveness of natural attenuation and in situ treatment of organic contaminants.

Presented by Bill Deutsch, Geochemistry Services LLC

Perth – 20th November 15 – 9am – 4pm

A Geologist in Afghanistan – the adventures of a foolish geoscientist?

A Geologist in Afghanistan – the adventures of a foolish geoscientist?

GPIC February talk, Tuesday 10th February 2015, presented by James Llorca FAIG, FAusIMM, FSEG, Team Leader – Component II Mineral & Capacity Development, USAID – MIDAS Project.

James Llorca and Field Assistant

The talk is a presentation on the adventures of a possibly misguided geologist working in a war zone. It covers an overview of Afghanistan, its brief geology, prospectivity and the activities involved in conducting geological field work.

Also, it is understood that for the first time in GPIC history this talk will be delivered remotely. James’s talk will be something of an experiment: he will not be with us at the Basement on View. He will be giving his talk via Skype, from Kabul.

On the off-chance modern technology fails us on the night, bring an interesting rock – and we can discuss our disparate collection over our favourite drinkies.

About the Presenter

James is a qualified geologist with more than 30 years practical experience in both technical and management roles in the exploration and mining industry in Australia, Indonesia, the Philippines, China, Zambia, Africa and most recently, Afghanistan. This experience has resulted in highly developed technical skills in mineral exploration, geological interpretation and resource modelling in addition to JORC competency level resource estimations across various commodities. James also has significant experience in resource due diligence, technical exploration and mining appraisals, JORC and NI 43-101 compliance reviews.

James’ expertise in geological field mapping, mine geology, 3D orebody modelling, geostatistical analysis and estimation of resources and reserves, valuation and project management of natural resources has led him to his current role with MIDAS (Mining Investment and Development for Afghan Sustainability) which is a USAID funded project. His current role as Team Leader for Component Ii of the MIDAS Project is involved in Mineral Exploration and Capacity Development of the Afghanistan Geological Survey and the Ministry of Mines and Petroleum.

Australian Synchrotron Visit

AIG Victorian Branch Visit to the Australian Synchrotron

We were a happy team of geos that ventured beyond the MCG on the Monday after the AFL Grand Final in September to visit the Australian Synchrotron, which is about the size of the MCG!

Earlier this year Kaylene Camuti met the Synchrotron’s Dr Tamsyn Ross, who suggested that a group from the AIG should visit the facility. Consequently, a party of 17 from the Victorian branch made the trip to the Melbourne suburb of Clayton, near Monash University. We were greeted by Tamsyn and her colleagues, Dr Helen Brand, Dr Kathryn Spiers and Dr David Cookson, each of whom gave us a talk, and then guided our group around this most impressive facility. Images can be seen on Dropbox folder \AIG_Vic\Aus Synchrotron_2014-09-29.

It was a terrific visit. The Synchrotron is potentially a very powerful tool. We left the facility rather like a character in the Arthur C Clarke/Stanley Kubrick book/movie, 2001- A Space Odyssey – we’ve got ourselves this tool, but we’re not too sure where it’s going to lead us! But we are exploration geos so we’ve got to give it a go. David Cookson, who is Head of Beamline Science and Operations, was particularly keen to encourage smaller enterprises to use the Synchrotron, and emphasised that they would try to accommodate any testing that geologists might wish to do—at a modest rate. Note that for geos in New South Wales there is already a state-funded support scheme in place (see section on NSW Industry Synchrotron Access Scheme, below). It is also possible for geologists working in academia to apply for access through the merit system.

A synchrotron is a machine that produces intense light, which can be used to investigate the details of matter from the atomic- to the nano-scale.  It can be used for many different applications including, for example, determining mineral phases, characterising pore structures, or mapping mineral traces in sectioned rocks. The AS is currently used by scientists from a diverse range of disciplines including agriculture, pharmaceuticals, forensics, advanced materials – geologists and metallurgists already use it to study rocks and minerals, and there are many possibilities for professionals working in these fields.

The Australian Synchrotron

The Australian Synchrotron

In basic terms the Synchrotron comprises a centrally-located electron gun, an accelerator, an inner booster ring, and an outer storage ring. Electrons are generated by the electron gun and accelerated to near the speed of light before being transferred to the storage ring where they are manipulated to give off light. The electrons circulating the storage ring are kept at a constant energy, apparently completing 1.4 million laps of the storage ring every second for about three days, all the while being used to produce beams of intense synchrotron light. Radiating tangentially from the storage ring are nine ‘beamlines’ – where the light generated in the storage ring is conditioned (filtered and focussed) as it propagates.

The Australian Synchrotron

1. Electron Gun: Electrons are generated inside an electron gun by heating a barium compound cathode to ~ 1000°C. Bunches of electrons are accelerated away from the cathode surface and out of the gun using 90,000 volts.

2. Linear Accelerator (Linac): In the Linac, the electrons are accelerated to 99.9987% of the speed of light. They exit the linear accelerator with 100MeV of energy. The energy used to accelerate the electrons comes from a radio frequency (RF) current of 3GHz. Radio frequencies are part of the electromagnetic spectrum, just like infrared light, but they have lower energy levels and therefore longer wavelengths. The spacing of the electron bunches matches the wavelength of the RF current, thus ensuring that the electrons receive a ‘push’ through the regions where the RF current is applied.

3. Booster Ring (synchrotron): The electrons are transferred from the Linac to the Booster Ring, where their energy is boosted to 3GeV using more RF energy. In the Booster Ring, dipole electromagnets force the electrons to adopt an almost circular path. The electrons complete approximately 1 million laps in half a second, before passing into the Storage Ring.

4. Storage Ring: In the Storage Ring, electrons circulate at aconstant energy for many hours, and continuously generate intense synchrotron light. To ensure the number of electrons circulating remains nearly constant, they can be topped up by injecting more into the ring approximately every few minutes. An electron will complete around 1.4 million laps of the Storage Ring every second.

5. Beamlines: The synchrotron light – created by bending the path of the electrons through magnetic fields – is then channelled from the Storage Ring down long pipelines, called beamlines, so that scientists can utilise it for research. Each beam line includes different types of filters, mirrors and other optical components that prepare the light for use in a range of different scientific experiments.

6. End Station: At the end of each beamline is an End Station – a laboratory where the synchrotron light interacts with a sample. Detectors positioned around the sample measure how the light is transmitted, emitted, scattered or diffracted (depending on the experiment) by the sample. Researchers use this information to determine the composition or atomic structure of the sample, or to create a map-like image of the sample.

For scientists visiting the Synchrotron the fun begins at the end of each beamline where the end-station and user cabin are located. Scientists mount samples in the end-station and control the experiment while sitting in the cabin. It is in the end-station that a geologist could present a sample to be zapped by the very narrow, very intense beam of light (at X-ray or infrared frequencies). Depending on the technique, a variety of detectors will measure how the light is transmitted, emitted, scattered or diffracted by the sample. On the XFM beamline a geologist could, for example, create an elemental map of the surface of a rock or mineral sample – but each of the nine beamlines has a unique function with a wealth of possibilities.

The primary capabilities and basic applications of each of the Synchrotron’s beamlines is given in the table below.  Uses of any given beamline may extend beyond what is given here, and interested parties are encouraged to enquire at the Synchrotron about any ideas they might have. Tamsyn Ross and her colleagues are preparing a technical article for AIG NEWS (Ross, T., et al, (in prep): working title is ‘Geological and metallurgical uses for the Australian Synchrotron’).

As mentioned above, for researchers working in industry in New South Wales there is a state-funded support scheme already in place.

NSW Industry Synchrotron Access Scheme

The NSW Industry Synchrotron Access Scheme is a program that is currently being run by the NSW government which allows bodies conducting commercially-relevant research within NSW to apply for fully-funded beamtime on any of the beamlines at the Australian Synchrotron. The advantages of applying for beamtime through the NSW Industry Synchrotron Access Scheme are that there is no need to publish the work (as would be necessary through the standard merit access program), little is required in the way of preparing a proposal for the work (with assistance from the applicant, the Synchrotron handles most of the paperwork) and access to the Synchrotron through this scheme is typically more rapid than through the merit access program (access to some beamlines may still be possible in late 2014). A further important point is that the applicant retains their IP on work.

The Beamline Industry Group is a group of scientists dedicated to supporting commercial research taking place at the Synchrotron, in particular that of applicants to the NSW Industry Synchrotron Access Scheme. They offer obligation-free exploratory talks about potential projects, assistance with experimental design and expert support during beamtime – other services available include data analysis and reporting.

Gold14@Kalgoorlie Symposium

gold14@Kalgoorlie

Gold14@Kalgoorlie: an International Symposium in the home of Australia’s gold industry, 8-10 October 2014

Kalgoorlie, home of the Super Pit, is the perfect location for the Australian Institute of Geoscientists (AIG) Gold14@Kalgoorlie Symposium to be held between 8-10 October. The symposium will be a truly international event, with delegates attending from Africa, the Americas, Asia, Europe and the Pacific and bringing together notable geoscientists from academia and the gold industry.

“This conference is shaping up to be the most important gold geoscience conference in Australia since Bicentennial Gold88 in 1988” said the symposium Organizing Committee Chairman and industry consultant Julian Vearncombe.  The highlight is a 3-day conference of talks and posters on various aspects of gold deposits, provinces and exploration.

Keynote speaker, Ed Eshuys, known for his involvement in the Plutonic, Bronzewing and Jundee gold discoveries in WA in the 1990s, will open the conference with an address on the importance of exploration to the Australian economy.

“Australia’s gold exploration story is one of great success” Neil Phillips, a consultant and Adjunct Professor with the University of Melbourne said. “Claims that gold exploration has not been successful are potentially dangerous and may lead to misallocation of exploration and research funding. The Government data shows that Australia is not only replacing the gold that it mines but systematically adding to the inventory.”

“Since 1979, Australia has achieved what no other country has in this period, discovering 16,500 tonnes of gold at a cost of $40 per ounce. This low exploration cost is a measure of how Australia’s exploration industry has been unequivocally successful in discovering gold, especially when compared to today’s gold price of around US$1220.” Professor Phillips said.

Recent Australian gold discoveries include DeGrussa copper-gold deposit (WA), Tropicana deposit (WA), McPhillamys deposit (NSW) and Andy Well (WA). The symposium will also hear of recent successes at Pegasus, and Invincible near Kalgoorlie.

In the last ten years Australia has added 6,000 t of gold to its Economic Demonstrated Resource (EDR, Geoscience Australia, 2012). At the end of 2012, Australia’s EDR of gold was about 9,909 t. This figure suggests that there are enough resources for the next 30 years of mining at the current production rate.

Gold is currently a primary output of about 75 mining and processing operations in Australia; and these mines produce about 250 tonnes of gold a year, almost 10% of world production, and second only to China.

The goal of Gold14@Kalgoorlie is to present the innovative geological practices and technological innovations that are contributing to the continued success of an industry that employs 25,000 personnel across Australia. Neil Phillips sums up “The exploration industry’s aim is discovering better quality gold ounces which are higher grade, easier to extract and better located”.  “Whether such ounces are in new areas (greenfields) or established areas (brownfields) is of secondary importance. Commonly being near to existing infrastructure can be a big advantage.”

The Symposium runs from 8-10 October 2014 and will be accompanied by both pre- and post-conferece field excursions and workshops.
