AbstractThe Kimberlite Indicator Diamond Database (KIDD) hosted at the NT Geoscience office in Yellowknife is a database archiving kimberlite indicator mineral (KIM) grain counts reported within assessment reports of mining activity in the Northwest Territories. Despite its widespread use since its inception nearly 25 years ago, there has yet to be a formal assessment of the KIDD data structure, content and usability of this data archive. This presentation reports on these elements of KIDD and highlights some limitations and caveats of its data usage.
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 from suites of KIM); 3) Analytical information (processing techniques, processed size fractions, etc.); 4) Comments (mixed array of site attributes, analytical information, KIM information). The completeness and accuracy of reported KIM grain counts is variable. Only ~34% of all archived samples report total KIM grain count information. Individual KIM grain count reporting varies 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% of data reported within assessment reports are faithfully and accurately reported within KIDD.

Some limitations to the use of KIDD result from irregular reporting and non-standardized reporting formats. This is the case for sample weights and sampling site attributes which are highly valuable data when using KIDD as an archival or data mining source. 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.
Summary(Plain Language Summary, not published)
