Conglomerates in general (and breccias in particular) generally indicate deposition that occurred relatively close to the source area and/or a transporting medium that was either highly energetic (fast-flowing water) or highly viscous (glacial ice, debris flow, etc.) Sandstone: most of the particles are sand-sized Quartz sandstone or quartz arenite is composed mostly (around 90% or better) of sand-sized quartz grains Graywacke is a "muddy" sandstone that contains between 10% and 50% mud (clay or silt) sized particles.
