Résumé(disponible en anglais seulement)
The Canadian Cordillera is well endowed with mineral deposits and holds significant potential for new discoveries. Surficial media sampling has evolved as an effective mineral exploration approach and has had many successes. Given that the next generation of mineral deposits in the Canadian Cordillera will likely be concealed by sediments, surficial media sampling is a critical tool for exploring large regions, rapidly and cost effectively. Stream sediment, lake sediment, and till are routinely sampled for mineral exploration in the Canadian Cordillera. In this review, we highlight the application of geochemistry and mineralogy of stream, lake, and glacial sediments and discuss sampling strategies and interpretive concepts based on recent developments in using indicator minerals that can identify specific deposit, alteration and sources of geochemical anomalies.
