Sedimentary rock - Grain size: Particle size is an important textural parameter of clastic rocks because it supplies information on the conditions of transportation, sorting, and deposition of the sediment and provides some clues to the history of events that occurred at the depositional site prior to final induration.

Chem- some individuals make and sell traditionally handcrafted adobe brick. The simple process involves mixing soil, water, and sometimes straw
In commercial granite, the larger the grain size, the lower is the strength, and the greater is the brittleness, because mineral cleavage can manifest better in larger grains. A homogenous structure or a mildly-oriented one is a feature of magmatic rocks.
2018-10-28 · The predominating grain-size of the sample should be prominently apparent. The form of the plot should be unaffected by, and independent of, the sizing-scale used in making the test, thus affording, if desired, a means of direct comparison with data secured by a different sizing-scale.
