AbstractMuch of Canada has been sampled for indicator minerals to support mineral exploration activities. The application of indicator mineral techniques for exploration in glaciated terrains accelerated through the 1980s and 1990s as the potential for diamond deposits in the Canadian Shield attained broader appreciation and exploration success increased. Following the 1991 discovery of the Ekati deposit in the Lac de Gras area interest in indicator minerals increased enormously and there was an increased recognition of the need to better understand indicator mineral distribution in glacial deposits. Subsequently there have been a number of notable publicly funded initiatives to support centralized indicator mineral databases (e.g. Kimberlite Indicator Diamond Database - KIDD). There has also been an increased interest in applying indicator mineral techniques to the search for other commodities. Nevertheless, integration of the controls that glacial processes exert on indicator mineral dispersion remains poorly developed.
To address this issue the subproject on indicator minerals within the Target Geoscience Initiative 4 (TGI-4) is developing an Indicator Mineral Dispersal Atlas for selected regions and dispersal datasets in Canada. A preliminary activity has been to compile the published literature on indicator minerals and develop a library (database) of reference material for integration with other geoscience datasets. This report documents the structure and workflow developed for data entry and export from this library that uses Microsoft Access, Google Earth, and ArcInfo.
Summary(Plain Language Summary, not published)
The Targeted Geoscience Initiative (TGI-4) is a collaborative federal geoscience program that provides industry with the next generation of geoscience knowledge and innovative techniques to better detect buried mineral deposits, thereby reducing some of the risks of exploration. This documentation and workflow was developed as part of TGI-4 subproject on Indicator Minerals. It provides documents a workflow for the capture and presentaion of information from published sources. It provides step-by-step instructions for entering data into the Glacial Dispersal IM Plume Library (the Library). Descriptions and formats of all fields are provided with examples so that future data entry can be as consistent as possible. Data entry for spatial features into Google Earth is also explained, as well as processing of data in ArcMap which has been simplified with custom tools.
