Pi"so*lite (?), n. [Gr. a pea + -lite: cf. F. pisolithe.] Min.
A variety of calcite, or calcium carbonate, consisting of aggregated globular concretions about the size of a pea; -- called also peastone, peagrit.
⇒ Oolite is similar in structure, but the concretions are as small as the roe of a fish.
