About Breccia
Name:
Etymology: "Breccia" is Italian, meaning broken stones, rubble.
A coarse-grained clastic rock, composed of angular broken rock fragments held together by a mineral cement or in a fine-grained rock matrix; it differs from conglomerate in that the fragments mostly have sharp edges and unworn corners. Often, but not always, breccia fragments have shifted only slightly from their original positions and can be seen to fit together with neighboring fragments. Breccia may originate as a result of talus accumulation, explosive igneous or hydrothermal processes, collapse of rock material, or faulting.
Some Portland cement concrete may be visually similar.
