What Wikipedia says

Psammite (Greek: psammitēs "(made) from sand", from psammos "sand") is a general term for sandstone. It is equivalent to the Latin-derived term arenite and is commonly used in various publications to describe a metamorphosed sedimentary rock with a dominantly sandstone protolith.
