Serpentinite Specimen Metamorphic Rock Approx_ 1 3cm

When clay- and aluminum-rich rock is altered by water from geothermal systems, serpentinite is liable to form. Often found in low-grade metamorphic areas, serpentinite is composed of hydrated silicate minerals, particularly phyllosilicates. Greenish in color and smooth to the touch, serpentinite is often found as a plane of weakness in faulted rocks. This piece is useful in lessons on metamorphic rocks, low-grade deformation, and structural geology. Each sample is approximately 1" long and comes in a labeled plastic bag.
