Detritus refers to loose fragments of rock and mineral material that have been broken down by weathering and erosion. These fragments can range in size from boulders to clay particles and are typically transported by wind, water, or ice before being deposited as sediment. Detritus is a key component of sedimentary processes and plays a crucial role in the formation of sedimentary rocks.
