A clastic rock made of particles larger than 2 mm in diameter is either a conglomerate or breccia. A conglomerate has rounded clasts while a breccia has angular clasts. Since water transport rapidly rounds large clasts, breccias normally indicate minimal transport. They commonly form as rock-fall and debris flow ...Breccia is composed of coarse rock fragments held together by cement or a fine-grained matrix. 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. These indicate that the gravel was deposited very close to its sou…silica grains in the black breccia, one is surrounded by granitic material. This granitic material contains K-feldspar and acicular silica grains (possibly tridymite), similar in habit to those found throughout the gray breccia.
