Psammite

 Psammite (Greek: psammitēs "(made) from sand", from psammos "sand")^[1] is a general term for sandstone. It is equivalent to the Latin-derived term arenite^[2][3] and is commonly used in various publications to describe a metamorphosed sedimentary rock with a dominantly sandstone protolith.^[4] In Europe, this term was formerly used for a fine-grained, fissile, clayey sandstone.^[3] Pettijohn ^[5] gives the following descriptive terms based on grain size, avoiding the use of terms such as "clay" or "argillaceous", which carry an implication of chemical composition:
