Q: Sedimentary rocks in which the individual grains, whether rounded or angular in shape, are of the size of common sand, are defined as
  • A. Arenaceous rocks
  • B. Rudaceous rocks
  • C. Silt rocks
  • D. Argillaceous rocks
Correct Answer: Option A - Sedimentary rock classification based on size and shape of grains are– Arenaceous– Constituent particles are granule, sand example are grit, sand stone. They consists of grains varying between sizes of 2 and 1/16 mm and are called arenites. Argillaceous– Constituent particles are silt, clay and example are mud stone, shale. Rudaceous– Constituent particles are boulder, cobble, pebble and example are conglomerate, breccia.
