Serpentinite foliated or nonfoliated
Texture - foliated. Grain size - very fine grained; grains need to be observed under a microscope; sometimes contains porphyroblasts. Hardness - hard. Colour - variable, grey to black, but can form in a variety of colours dependent on parent rock composition. Mineralogy - extremely variable, dependent on the original composition of the parent rock.Serpentinite is a rock composed of one or more serpentine group minerals, the name originating from the similarity of the texture of the rock to that of the skin of a snake. Is serpentinite foliated? Serpentinite has a mottled greenish color, has the look & feel of hard candle wax, and ranges in texture from crystalline to “foliated”.
