Practical Inversion for Geoscientists

A short course on the why, how, and what of geophysical inversion

Presented by the B.C. Geophysical Society

Date: April 24th – 26th 2013

Address: SFU Downtown Campus; Vancouver BC

Registration:  Registration is now open!  Please fill out attached pdf form (link below) and click submit.  Registration will be complete once payment is made via Paypal link.  Delegates are asked to choose one workshop day among April 25th or 26th.

Day 1 – Presentations

Introduction to inversion in exploration

  • Reasons for doing inversion
  • Range of inversion options: magnetics, gravity, EM, IP-resistivity, seismic
  • Fitting geology and data

 Background on inversion

  • Unconstrained/constrained
  • Joint and collaborative
  • The future of inversion

Before inversion – forward modeling

  • forward modeling
  • petrophysics drives the story
  • complexity vs. adequacy 

Case studies

  • Potential fields
  • EM
  • IP-resistivity

Day 2 – Workshop with Case Studies
Multi-disciplinary teams will use geological, geophysical and geochemical data from two deposits (Babine Lake porphyry Cu-Mo, BC and Minto Cu, YK) to develop exploration targets. Teams will present their evaluations of the data to stimulate group discussion.

Inversion results for the available geophysical surveys will be presented to demonstrate state-of-the-art technology (http://geosoft.com/, http://www.mirageoscience.com/) and best practices.

Sponsors for the short course are currently being solicited. Please contact Victoria Sterritt at Victoria.Sterritt@teck.com for details. Proceeds go to the KEGS Foundation.
For those interested in more information about the short course, please email info@bcgsonline.org 

 The BCGS would like to thank RedTail Metals and Capstone Mining Corp. for providing access to the Babine Lake and Minto data sets.


February Technical Talk

SPEAKER: John A. Chapman, P.Eng

TITLE: The importance of mineral exploration and mining to humans in their space development activities

DATE: Thursday February 21st, 2013

TIME: 4:30pm

LOCATION: Room 451, 409 Granville Street (UK Building at Granville and Hastings)

ABSTRACT: There is presently a surge of government and commercial space initiatives that harkens the beginnings of a new age – that of space development beyond Earth orbit. Dot-com billionaires along with well educated and experienced space scientists, engineers and technologists have begun forming companies focused upon advancing human civilization toward utilization and occupation of the moon, mars and asteroids.

 The wealth from mines, from the dawn of recorded human history, is the epic march of mankind along the path of progress. It was the mines that made ancient civilizations such as Egypt, Greece and Rome great and in more recent times have created immense wealth to the benefit of the people of Europe, North America, Australia and now China, India, Brazil and Russia.

 Today, we are part of the “space generation”, crawling off the surface of the earth into the “oceans of space” – mining will continue to provide the capability for humankind to advance to the moon, mars and on to the stars.
