Breccia, a term adopted from the Italian to designate a mass composed of angular fragments of rocks of the same or different kinds, cemented together by an enveloping paste, as, for example, by infiltrated oxide of iron or carbonate of lime. Bones and fragments of bones cemented together by calcareous matter often occur upon the floors of caves in limestone: these accumulations are termed bone-breccia.
