Résumé(disponible en anglais seulement)
The Kimberlite Indicator Diamond Database (KIDD) developed by Northwest Territories Geoscience Office is a relational database archiving kimberlite indicator mineral (KIM) grain counts reported within assessment reports of mining activity in the Northwest Territories and Nunavut. KIDD archives four main types of sample data and metadata: 1) sample and site descriptions (general sample attributes: sample number, location, etc.); 2) information on KIM (grain count data for suites of KIM); 3) analytical information (processing techniques, processed size fractions, etc.); 4) comments (mixed array of sample site attributes, analytical information, KIM information). The completeness and accuracy of reported KIM grain counts is variable. There are KIM grain count entries for only ~34% of all archived samples. Entries for individual KIM grain counts vary between ~0.02% (diamonds) to ~16% (garnets). Despite some limitations in grain count reporting, the data contained within KIDD are of high quality and integrity: 87-100% of data reported within assessment reports are faithfully and accurately reported within KIDD. Limitations to the use of KIDD also result from irregular and non-standardized inconsistent reporting of sample weights and sampling site attributes. These limitations result not from an absence of data but from the database structure itself that does not contain proper fields for standardized reporting of these attributes. Overall, KIDD offers a useable archival dataset of high data quality. However, numerous caveats and limitations in data reporting require careful data evaluation by the user.
