Serpentine is a metamorphic rock. There are different methods being researched but sequestration through rock weathering has enormous potential and we should look forward to seeing the benefits of this stable and natural process. Serpentinite often contains many veins, some of which may be filled with the fibrous mineral chrysotile (a form of asbestos). Formed deep within the earth's mantle, serpentine rocks found their way to the surface over millennia. Naturally-occurring asbestos, often found in serpentine rock formations, is present in several foothill areas of Placer County. Loose asbestos fibers cause lung disease if you inhale them.
