Abstract. For diamond exploration in glaciated terrains, Kimberlite Indicator Minerals (KIMs) are those minerals, contained in glacial deposits, that are characteristic of kimberlite, the dominant host for diamonds. As KIMs are many times more numerous in the kimberlite host rock than are diamonds, they are an important...
