sedimentoi

Sedimentoi is a coined term used in some discussions of sedimentology to describe a proposed grouping of sedimentary deposits that share a set of hypothetical characteristics. It has no universally accepted definition, and it is not part of standard geological nomenclature. In practice, references to sedimentoi arise mainly in pedagogical contexts or speculative writing to illustrate how deposit types might be classified when multiple processes interact.

Etymology and scope. The word combines sedimentum, the Latin for sediment, with a plural-sounding suffix -oi, used in some theoretical coinages. Because the term lacks formal criteria, its scope is variable across sources. Authors may invoke sedimentoi to discuss deposits formed by rapid or episodic deposition, notable diagenetic features, or distinctive microstructures, but there is no fixed set of criteria that identifies a sedimentoi deposit.

Relation to other concepts. Sedimentoi is presented as a conceptual aid rather than a diagnostic category. It is sometimes contrasted with established classifications in sedimentology, such as lithofacies, depositional environments, or sedimentary rock types. Users should treat it as a provisional idea rather than a supported taxonomy.
