Metamorphic rock identification table.Serpentinite is composed of minerals of the serpentine group. It forms by regional metamorphism of deep-sea rocks from the oceanic mantle. It is common beneath the oceanic crust, where it forms by the alteration of the mantle rock peridotite. It is seldom seen on land except in rocks from subduction zones, where oceanic rocks may be …Non-foliated metamorphic rocks do not have aligned mineral crystals. Non-foliated rocks form when pressure is uniform, or near the surface where pressure is very low. They can also form when the parent rock consists of blocky minerals such as quartz and calcite, in which individual crystals do not align because they aren’t longer in any one ...The two most common examples of non-foliated rocks are quartzite and marble.
