Biogenic sediment
Biogenic sediment consists of particles formed from the remains of living organisms, such as shells, skeletons, and algae. These sediments accumulate on the ocean or lake floor over time as the organisms die and their hard parts settle and fossilize. Common examples include calcium carbonate and silica-based materials from marine creatures like corals, foraminifera, and diatoms. Biogenic sediments provide important clues about past life and environmental conditions, and they play a crucial role in forming natural resources like oil, gas, and minerals.
