WebReaction rim is a genetic term for a border of secondary minerals formed at the margin of a primary grain in an igneous or metamorphic rock. Its use implies that the secondary minerals have formed as a result of reactions between the primary grain and the adjacent primary grain, a fluid, or a melt.
