The Ófalu serpentinite as a 10 m thick sill-like body lies in the metamorphites of the Ófalu Group. It consists of two varieties petrographically: ]. massive serpentinite, 2. sheared serpentinite due to the powerful tectonism of the "Mecsekalja Tectonic Belt" including the Ófalu Group. Main minerals of the serpentinite are lizardite, clinochrysotile, antigorite and chlorite with disseminated ore grains among them, such as chromite, magnetite, pentlandite, heazlewoodite and subordinate sulphide minerals. Based on data of the chemical analyses and Ni/Co ratio this rock belongs to so called "Alpine-type" serpentinites. The Ni and Cr content as well as MgO/SiOa ratio suggest an ultramafic- more accurately harzburgite-lherzolite origin. Process of serpentinization took place at 450—500 °C temperature and 0,5—1 Kb pressure. The serpentinite mass together with parent rocks of metamorphites of the Ófalu Group suffered a low grade regional metamorphism at the circumstances of the greenschist-amphibolite transitional facies.
