Lithogenic sediment refers to particles that originate from the weathering and erosion of rocks. These sediments are primarily composed of minerals and can include fragments of granite, sandstone, and other rock types. They are transported by natural processes such as water, wind, or ice and eventually settle in various environments, including rivers, lakes, and oceans. This type of sediment plays a crucial role in the formation of sedimentary rocks, which are created when lithogenic particles accumulate and compact over time. Examples of lithogenic sediment include sand, silt, and clay, each varying in size and composition, contributing to the diversity of geological formations.
