Physical properties

Formation & geological history

Formed through serpentinization, a low-temperature metamorphic process altering ultramafic rocks like peridotite and pyroxenite in the presence of water and heat, typically at tectonic boundaries.

Uses & applications

Used as ornamental stone, carving material, gemstone beads, source of magnesium, historically as asbestos (chrysotile variety), and decorative architectural tiles.

Geological facts

Serpentine gets its name from its similarity to snake skin due to its slick texture and mottled green coloration. It is the official state rock of California.

Field identification & locations

Identified in the field by its distinctive soapy or waxy feel, soft hardness, and shades of green. Commonly found in subduction zones and ophiolite complexes globally, such as in California, Italy, Greece, and New Zealand.
