The Microprobe Analyses and Mineral Interpretation dataset comprises published raw microprobe analyses data of kimberlite indicator mineral (KIM) grains and other non-KIM grains from samples collected by government and industry throughout Alberta between 1993 and 2011. Data was compiled from mineral assessment reports, and government and academic publications.

This dataset comprises 34 568 microprobe chemical analyses of mineral grains obtained from a total of 3 387 samples. Mineral grains include xenocrysts from kimberlite and ultramafic intrusions as well as heavy minerals from sediment and bedrock samples of the Alberta basin. The dataset also includes new derived mineralogical reinterpretations for kimberlite indicator mineral grains to level past classifications performed by different surveys and methodologies through time. Mineral reinterpretations were performed based on the schemes described in the metadata record of the AGS publication: Alberta kimberlite indicator mineral (KIM) microprobe analyses, Digital Data 2020-0009.

Additionally, other minerals not necessarily related to kimberlites were included in the dataset. These other minerals comprise amphibole, biotite, corundum, hematite, magnetite, orthopyroxene, phlogopite, quartz, rutile, staurolite, titanite and tourmaline.
