Siliceous Sediments

Siliceous sediments are types of sediments composed mainly of silica, often from the hard remains of tiny marine organisms like diatoms, radiolarians, and sponge spicules. These biogenic particles settle to the ocean floor, forming layers over millions of years. Such sediments are common in deep-sea environments and areas with high biological productivity. The silica content makes these sediments durable and sometimes forms deposits like diatomaceous earth, which has various industrial uses. Overall, siliceous sediments are essential in understanding oceanic processes, biological activity, and the formation of certain mineral deposits.
