Naleid

Naleid is a term used in the field of geology to describe a type of sedimentary rock that is formed from the accumulation and lithification of organic remains, such as plant or animal debris. The term is derived from the Greek words "nales," meaning "ashes," and "eidos," meaning "form." Naleids are typically composed of fine-grained material, such as clay or silt, and may contain fossils of the original organisms. They are often found in marine environments and can provide valuable information about past ecosystems and climate conditions. Naleids are classified as a type of argillaceous sedimentary rock and are commonly used in geological studies to understand the history of Earth's oceans and atmosphere.
