breccia

comparison with conglomerate

Like conglomerate, breccia contains at least 30 percent of gravel-sized particles (particles over 2mm in size), but it is distinguished from conglomerate because the rock fragments have sharp edges that have not been worn down.

composition

Breccia is composed of coarse rock fragments held together by cement or a fine-grained matrix.
