Geology from Geophysics

Geology from Geophysics

Geology from Geophysics – a one day symposium presented by ASEG in conjunction with ASEG-PESA 2015

With exploration increasingly taking place ion areas with poor outcrop or under significant cover, the need for explorationists to obtain geological information from geophysical data has never been greater.

Intended for geoscientists working in the minerals industry, this 1 day symposium brings together industry and academic geoscientists who are world-leaders in the fields of practical geophysical data interpretation and integration of geoscientific datasets for mineral exploration applications.

Regional Metallogenic to Local Controls on Circum-Pacific Gold and Copper Deposits

Regional Metallogenic to Local Controls on Circum-Pacific Gold and Copper Deposits is a short course to be presented prior to PACRIM 2015 (Workshop W2).  This one-day workshop will be held at the Conrad Hotel in Hong Kong, China on the 17th of March, 2015.  The course will be of particular interest to geoscientists seeking to broaden their understanding of ore-forming processes and who wish to explore for gold and copper deposits in the circum-Pacific region.

The workshop will consist of two parts. The first, presented by Steve Garwin, is titled Tectonic and Structural Controls to Gold and Copper Mineralization in the Circum-Pacific Region. This presentation will consist of three main topics:

  1. Tectonic and regional structural controls for gold and copper mineralization in the Southeast Asia – Western Pacific and Peruvian Andes
  2. Examples of district- and deposit-scale controls to porphyry and epithermal deposits in Indonesia, Japan and Peru
  3. Controls to Carlin-type deposits in northern Nevada, USA and Guizhou Province, China.

The second part of the course, presented by Craig Hart, is titled Intrusion-related Gold Metallogeny. This presentation will consist of three main topics:

  1. Intrusion-related gold systems and classifications, with an emphasis on Alaska and the Yukon
  2. Redox controls on intrusion-related metallogeny
  3. Controlling features of mineralizing intrusions.

Latest Australian Geoscientist Employment Survey Open for Submissions

In the first quarter of 2014 the AIG Australian Geoscientist Employment survey recorded the highest levels of unemployment and underemployment since the surveys commenced in 2008. The September quarter survey showed the first signs of improvement in employment conditions after a protracted downturn. This survey is intended to measure whether this improvement continued through to the end of 2014, setting the scene for the New Year.

With your support, The AIG Australian Geoscientist Employment Survey is now regarded as a trusted indicator of geoscientist employment specifically, and an indicator of the health of Australia’s exploration and mining sector more generally. We need your support, for a few minutes every every quarter to maintain the value of this series of surveys.

The surveys provide a snapshot of employment opportunities for Australian geoscientists based on “hard data” from a representative sample that is used in representations to government, and for use in a range of other areas by both AIG and industry representative bodies with which AIG shares the survey results.

Click here to complete the survey. The survey collects no identifiable, personal information and takes less than two or three minutes to complete. Your time spent completing the survey really helps to make a difference to the standing and knowledge of our profession.   The survey will remain open unto 31 January 2015.

Exploration Skills for Graduate Geoscientists

The five day exploration skills course for graduate geoscientists planned for Kalgoorlie, Western Australia, 19-23 January 2015, organised by the AusIMM Geoscience Society and Digirock and supported by AIG, has been postponed until later in 2015.

The course brochure which provides course content and structure information is available here.  Watch the web site for information regarding rescheduling of this valuable course.

Unique Student Identifier (USI)

From January 1, 2015, all students undertaking any form of training with a nationally recognised training provider in Australia will be required to have a Unique Student Identifier (USI).  The USI program is administered by the Australian Government Department of Industry.

A USI is an account (or reference number) made up of numbers and letters. The USI will allow your students online access to their training records and results (transcript) through their online USI account.

A USI is required for both new and continuing students undertaking nationally recognised Vocational Education and Training (VET) courses to receive their statement of attainment or qualification.

A USI may be obtained online and at no cost to students.  This USI will stay with your students for life and be recorded with any nationally recognised VET course that is undertaken from the 1 January 2015.

Students can access their USI accounts online from computers, tablets or their smart phones anytime.

2015: International Year of Soils


The 68th UN General Assembly has declared 2015 the International Year of Soils (IYS). 

The Food and Agriculture Organization of the United Nations has been nominated to implement the IYS 2015, within the framework of the Global Soil Partnership and in collaboration with Governments and the secretariat of the United Nations Convention to Combat Desertification.

The IYS 2015 aims to increase awareness and understanding of the importance of soil for food security and essential ecosystem functions.

The specific objectives of the IYS 2015 are to:

  • Raise full awareness among civil society and decision makers about the profound importance of soil for human life;
  • Educate the public about the crucial role soil plays in food security, climate change adaptation and mitigation, essential ecosystem services, poverty alleviation and sustainable development;
  • Support effective policies and actions for the sustainable management and protection of soil resources;
  • Promote investment in sustainable soil management activities to develop and maintain healthy soils for different land users and population groups;
  • Strengthen initiatives in connection with the SDG process (Sustainable Development Goals) and Post-2015 agenda;
  • Advocate for rapid capacity enhancement for soil information collection and monitoring at all levels (global, regional and national).

Geophysical signatures of mineral systems; more than bumps


8 CPD hours“Geophysical signatures of mineral systems; more than bumps” is a workshop being held as part of the ASEG-PESA 24th International Geophysical Conference and Exhibition in Perth, 15-18 February 2015.  The convention organisers have decided to make workshop registration available to attendees who have not registered for the conference itself.

Date: Thursday 19 Feb
Cost: Standard $180, students $80 (Students must provide proof of student status)
Location: Meeting Room 10, Perth Convention and Exhibition Centre

Workshop Details

It is generally accepted that the shallow, easy to define ore bodies were recognized first and developed. In the past 20 years, the discovery performance across virtually all mineral sectors has fallen, resulting in growing concern that if unchecked, there could be shortfalls in a number of commodities within the next 20 years.

The collective sense is that the geological column hosts more deposits than have been found to date but these are expected to be at greater depths than have typically been explored before. To be able to operate in this environment, new approaches to the identification of deposits is required and the concept of a mineral systems approach, first suggested 20 years ago, has emerged as a powerful means to build strategies and capabilities going forward. In terms of geophysical exploration, the major change that will be required is a shift from a focus almost entirely on direct targeting of deposits with geophysical surveys to a staged process where geophysical approaches are used initially to help define the pathways in the Earth which carried the mineralizing solutions which formed the target deposit.

These pathways would provide a much larger target to explore for and if detected and mapped, should allow explorers to follow the pathway to the location of potential deposits. This task is different from most geophysical studies undertaken, where the focus has been typically on improving the direct targeting capabilities and not the larger scale mapping problem that a mineral systems approach will require. In the current assessment, a review is undertaken of what is seen as the current state-of-play for a number of major deposit styles and how geophysical data is being used at present to explore for these. The assessment overall is encouraging but major challenges remain outside of the technical issues of defining a mineral systems strategy that relate primarily to human resources and the commercial environment.

This forum will examine the current state of understanding of geophysical signatures of mineral systems; current examples, on-going research and areas which require further assessment. A major tenant that is already apparent is that the successful development of undercover exploration strategies will require a degree of integration of geophysical outcomes with other geoscience data not typically achieved historically.
