Which clastic sedimentary rock may have a grain size of 0.1 cm?

The clastic sedimentary rock that may have a grain size of 0.1 cm is sandstone. Sandstone is primarily composed of sand-sized particles, typically ranging from 0.0625 mm to 2 mm in diameter. A grain size of 0.1 cm (1 mm) falls well within the typical range for sandstone, which can vary in color and composition depending on the minerals present.
