saponite
Very Low (Specialist)Technical/Scientific
Definition
Meaning
A soft, soapy clay mineral.
A trioctahedral mineral of the smectite group, often formed by hydrothermal alteration of magnesium-rich rocks; also known as 'soapstone' or 'massive saponite' in industrial contexts.
Linguistics
Semantic Notes
Term is exclusively geological/mineralogical. Does not refer to manufactured soap. The 'soapy' quality refers to its greasy or slick tactile sensation.
