Serpentinite forms from the metamorphic alteration of ultramafic silicate rocks, particularly peridotite and pyroxenite, where serpentine minerals replace igneous minerals of olivine and pyroxene. Deserpentinization is the process whereby serpentinite is progressively dehydrated during prograde metamorphism, ultimately leading to the reappearance of anhydrous ferromagnesian minerals. Therefore these rocks do not fall into neat categories .

Metamorphic rocks result from intense alteration of any previously existing rocks by heat and/or pressure and/or chemical change. This is at odds with the notion that oceanic serpentinite is brucite-poor, which resulted from a sampling bias toward dredged rocks that had undergone weathering. Factors that are boosting the growth of the market, and giving a positive push to thrive in the global market is explained in detail.
