| Abstract | For more than 50 years, researchers at the Geological Survey of Canada (GSC) have developed, tested, and refined till geochemical and indicator mineral methods as applied to mineral exploration,
provenance studies, and environmental research in glaciated terrain across Canada. This cumulative experience and knowledge were used to produce and publish the GSC's first comprehensive field and laboratory methods protocol manual for till
geochemical and mineralogical surveys in 2011. The publication being presented here provides an update and augmentation of this earlier version and presents the major concepts of till as a sample medium, glacial dispersal, and field and laboratory
procedures.
These protocols are used by the GSC to guide till sample collection, sample processing, geochemical and indicator mineral analyses, implementation of quality assurance/quality control (QA/QC) procedures, archiving methods, and data
reporting by the Geological Survey of Canada. Using consistent sample media and making diligent field notes and observations are also considered fundamental to the protocols, and are presented herein. The protocols will be of value to
provincial/territorial government geological agencies, the mineral exploration industry, and academia and we hope they will benefit from the use of this manual.
Adopting a common set of protocols allows the GSC, other researchers, and exploration
geologists to directly compare till geochemical and indicator mineral data sets from various parts of Canada and ensures proper minimum levels of QA/QC for all till geochemical and mineralogical data. |
| Summary | (Plain Language Summary, not published)
This report is an update and expansion of GSC protocols for till samples first published in OF 6850 in 2011. The protocols cover the collection, analysis
and reporting of till geochemical and mineralogical data. The protocols were established as part of the GEM Program and used by all scientists to provide consistent and comparable data between GEM map areas across Canada. |
