Drill Core, Structure and Digital Technologies

Dr Julian Vearncombe will present a one-day short course dealing with the collection and use of important structural data from oriented drill core.

drill core

In the mineral exploration industry, diamond core drilling provides the opportunity to collect structural data relating to a target or deposit. This enables improved and early knowledge and understanding of geological and mineralisation controls of a target, with an outlook to creating all-inclusive informative models from combined surface mapping, geophysics and downhole lithology and geochemical assay data. Quality structural data are invaluable to any project, from greenfield exploration to ore body definition in an advanced project with established reserves. Understanding the structural context of a project enables further exploration, ore envelope and shoot definition, and geological control on parameters for grade interpolation.

This short course summarises the technologies available in exploration and mining and describes techniques of core orientation, marking-up, structure measurement and the visual representation of structural data. We provide a critical comparison of tools and methods available at each stage of the process.

The course is based on the published research paper: Bright, S., Conner, G., Turner, A. and Vearncombe, J.R. 2014. Drill Core, Structure and Digital Technologies. Applied Earth Sciences (Transactions Institute Mining, Minerals and Metallurgy B), 123: 47-68.

The course venue is Building 034, Room 127, James Cook University.

AIG Queensland Branch Friday Seminar: pXRF geochemistry: use and abuse in exploration and mining

 

Print

The pXRF Friday seminar being held in Brisbane 13 November has received some fantastic funding from REFLEX to allow AIG to offer students and unemployed ten free registrations.  Please tell your student and unemployed colleagues and friends (who also need to be AIG members)  about this offer.  First in – first served.  Contact Rod Carlson prior to registering.

Free pXRF certification training is now also being offered by Olympus on Thursday 12 November 9am-1pm at the AMC offices in Brisbane.  Again, please email Rod Carlson to reserve a place before Wednesday 11 November. This is an offer too good to turn down for anyone contemplating minerals exploration as a potential career.

Introduction to Groundwater Geochemistry

ALGA will be presenting Bill Deutsch’s Introduction to Groundwater Geochemistry course in Perth and Brisbane during November.

This is an introductory 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 geochemistry that is necessary to understand natural and contaminated systems and how the composition of groundwater evolves along its flowpath in the subsurface.

Geochemical processes that will be described and discussed include solution complexation reactions, solution/gas interactions, mineral dissolution/precipitation, oxidation/reduction, and adsorption/desorption. 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 have a better understanding of the types of geochemical processes that affect groundwater composition, the importance of collecting sufficient data to understand site-specific geochemical systems, and how to use data to evaluate contaminant occurrence and mobility in the subsurface.

This course is being held in Perth and Brisbane to supplement the Introduction to Organic Groundwater Geochemistry Course.

Perth – 17th November 15 – 9am – 4pm
Brisbane – 25th November 15 9am – 4pm

Visit the ALGA web site for further details.

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
Melbourne – 23rd November 15 – 9am – 4pm
Brisbane –  27th November 15 – 9am – 4pm

Regolith Geochemistry – call for presentations

The AIG WA Branch has set the date for a one day session on REGOLITH GEOCHEMISTRY to be held at Burswood on Swan on October 26th 2015.

We are seeking expressions of interest to present approximately 30 minute talks associated with:

  • The geochemistry of weathering – how and why it happens and the implications for exploration.
  • Geochemical controls and constraints on element mobility in weathered material.
  • Tools for analysis and interpretation of regolith
  • Case studies.
  • Detection of mineralisation beneath/within weathered cover – with emphasis on geochemical process as opposed to empirical observations.
  • Case studies within the context of above.
  • Developments in hydro-geochemistry

Interested? Please contact Marcus Willson 

Watch the AIG events calendar for further details of the seminar.
