    What Is The Grain Size Of Igneous Rocks?

    gravel is classified by particle size range and includes size classes from granule- to boulder-sized fragments. in the udden-wentworth scale gravel is categorized into granular gravel (2 to 4 mm or 0.079 to 0.157 in) and pebble gravel (4 to 64 mm or 0.2 to 2.5 in).
