The estimated range of sizes for each type of particle is indicated by the bracket with the average size indicated by the arrow head. Rock fragments, for example, usually range in size from sand to the largest of particle sizes with an average size being about pebble size. Most quartz grains, on the other hand, ranges in size from pebble to silt with an average size of sand. The only size that uses a mineral name is clay-size, most likely because clay minerals dominate the clay-sized particles.. Ocean Sediments. Ocean Sediments.
