Serpentinisation of tectonized Harzburgites rocks in Ophiolits of Ashin has occurred in two different phases; in the first phase this phenomenon has taken place in a static and calm condition without any mechanical deformation of the hosting Harzburgite rocks; meanwhile the ferromagnesian minerals such as olivine and pyroxene have transformed into pseudomorphous Lhizardite and Bastite minerals [17].
