Please join us for our next Earthbound / Geological Association of Canada – Pacific Section talk on IOCG deposits at the BC Geological Survey, 3rd floor, Room 3001, 1810 Blanshard Street, Victoria, on Thursday October 19, 2017 from 2 to 4 pm.
Title: Iron oxide and alkali-calcic alteration facies as vectors for IOCG and affiliated deposits
By: Dr. Louise Corriveau
Research scientist, Geological Survey of Canada

Content of the presentation:
Brief overview of deposit types, distribution, ages, settings, resources, examples, alteration facies, ore deposit model(s). Geological and geochemical footprints and progradation of alteration facies, breccia and mineralisation: definition, types, mineral assemblages, prograde, retrograde and telescoped metasomatic reaction paths that lead to IOCG and affiliated deposit deposits.
- Na to Na-Ca-Fe alteration facies, albitites and albitite breccias
- HT Ca-Fe alteration facies, veins, transitional skarns and IOA (iron oxide-apatite) deposits
- HT to LT K-Fe, K-skarn to epithermal alteration facies, breccias, IOCG (iron oxide copper-gold) deposits, Co-Bi and K-skarn variants, and albitite-hosted U and Au-U-Co deposits
- Geochemical footprints and element mobility across ore environments
