Intro to Geology
Grain size refers to the diameter of individual particles or crystals in sedimentary rocks and sediments, which plays a crucial role in their formation and classification. The size of grains can indicate the energy of the environment in which the sediments were deposited, helping to interpret geological history. Understanding grain size is essential for differentiating between types of sedimentary rocks and their depositional environments.
