GAC-MAC 2016 Special Session 6 (SS6) – Indicator minerals in till and stream sediments

New discoveries of economic mineral deposits in Canada are likely to be covered by glacial sediments.  Therefore, mineral exploration methods for the discovery of buried mineralization need to be developed. Recent progress has been made using indicator minerals recovered from unconsolidated glacial and fluvial sediments, to detect buried mineralized bedrock sources. This special session at GAC – MAC 2016 (Whitehorse, YT) will present the latest developments in the use of indicator minerals in mineral exploration, with key examples from the Cordillera on a variety of mineral deposits types (porphyry, specialty metals, base metal, and more). This special session invites presentations on: drift prospecting and stream sediment case studies applicable to mineral exploration; advances in deposit indicator mineral assemblages and characterization of their trace element and isotopic signature; current models of growth, decay, and flow of the Cordilleran ice sheet and the implications for glacial transport history; sample media selection, processing, and quality control/assurance; and advances in traditional till matrix geochemistry. The session will emphasize developments in stream sediment and drift exploration applications in the high relief regions and interior plateaus, but other novel and innovative applications of drift prospecting science are welcome.

We invite you to submit an abstract to this indicator mineral special session. Abstracts can be submitted until January 31st  at www.whitehorse2016.ca.

GAC-MAC 2016 Workshop 1 (WS1) – Indicator minerals in till and stream sediments of the Canadian Cordillera  (Pre-conference Workshop, 30-31 May, 2016 )

New discoveries of economic mineral deposits in Canada are likely to be covered by glacial sediments. Therefore, new methods for the discovery of buried mineralization need to be developed. A two day workshop on indicator minerals in till and stream sediments of the Canadian Cordillera, and their application to mineral exploration, is being offered at GAC - MAC 2016 (Whitehorse, YT). The first part of day one will present current models of growth, decay, and flow direction of the Cordilleran ice sheet, discuss in detail the genesis of till and what till facies are most appropriate for use in drift prospecting, and why, despite the complexities of till generation, drift prospecting works.  The second part of day one focuses on recent work involving Quaternary and Holocene sediments that contain a detrital signal from porphyry Cu±Au±Mo, specialty metal (e.g., niobium, rare earth elements), base metal and other vein-related gold deposits.  Discussions will include trace element composition of some key indicator minerals and how they can be fingerprinted to a bedrock source.  Day two will be field-based and focus on the origin and genesis of Quaternary-age sediments that can be sampled, or should be avoided, for drift prospecting purposes.  As such, the fieldtrip will emphasize the recognition of basal till (the ideal sample medium for a till geochemistry and mineralogy survey) and differentiate diamictons of different origins. Field stops will also introduce other Quaternary sediment types commonly observed in the Canadian Cordillera. Because glacial transport history is critical for survey design and interpreting results, field stops will be made at key indicators of ice-flow movements and glacial transport directions.
