Where do you find platinum in a rock?

Platinum most often happens as disseminated grains in ironand magnesium-rich igneous rocks and in quartz veins associated with hematite, chlorite, and pyrolusite. When rocks climate, the heavy platinum accumulates as grains and nuggets within the ensuing placer deposits. Crystals are rare, but when found they’re cubic.
