👉 The term "lithoclastic" refers to a type of sedimentary rock that is composed primarily of rocks with very fine-grained, interbedded grains. These grains are typically quartz and mica-sized, and they are often found in small, irregular shapes. The presence of these interbedded grains leads to a smooth texture and a high degree of smoothness. Lithoclastic sediments are formed from the accumulation of debris or sediment over time due to geological processes such as erosion
