Till geochemistry surveys are targeted at regions of high mineral potential where glacial sediments cover and obscure the underlying bedrock. These surveys are conducted in conjunction with surficial geology mapping. British Columbia Geological Survey GeoFile 2017-09 provides the complete data set of publically available, regional-scale, till geochemical surveys. The surveys, carried out by the British Columbia Geological Survey, the Geological Survey of Canada, and Geoscience BC, compiles 39 reports released between 1992 and 2017, and includes geochemical data for 10,454 samples. Five Microsoft Excel tables generated from this database provide analytical determinations for the clay (<2 μm) and silt plus clay (<63 μm) size fractions of tills by inductively coupled plasma mass spectrometry after an aqua regia or modified aqua regia digestion, after a lithium metaborate fusion, and by instrumental neutron activation. These data tables can be brought into GIS software and integrated with other geoscience data to generate new exploration targets and design follow-up exploration programs. BCGS Open File 2016-2 is an index of geographically referenced, regional- and property-scale till geochemical surveys.

Latitude: 48.0° to 60.0°
Longitude: -139.5° to -113.5°

Additional Information

Purpose

The primary objectives of till geochemical studies are to identify geochemically anomalous sites that reflect areas of buried mineralization and investigate the patterns of glacial dispersal. The till geochemistry data tables can be brought into GIS software and integrated with other geoscience data to generate new exploration targets and design follow-up exploration programs.

Lineage Statement

The Till Geochemistry 2017 compilation is an update to the Till Geochemistry 2007 compilation.
