Here's why:
* Angular Fragments: Unlike other sedimentary rocks like conglomerate, which have rounded fragments, breccia's fragments are sharp and jagged. This indicates the source material didn't travel far before being cemented.
* Cemented Together: The angular fragments are held together by a matrix of finer-grained material, such as clay or calcite.
The texture of breccia is a key feature that distinguishes it from other sedimentary rocks.
