Abstract
The Gyod serpentinite body consists mainly of serpentinite, in addition, ultramafics and tremolite, anthophyllite schists are also present. Based on textural investigations the relic enstatite and olivine-bearing ultramafics constrain a harzburgitic protolith for the serpentinites. Low COr-content fluids penetrated the body and serpentinised the, resumably, ocean mantle-derived, depleted harzburgites. The serpentinization resulted in a new, lizardite, chrysotile-magnetite-talc-chlorite mineral assemblage. The tremolite and anthophyllite schists occur just certain parts of the sequence suggesting that their development was caused by localised impacts. The tremolite could have formed from a higher CO^-content fluids. The anthophyllite schists appear adjacent to the aplite dyke which, locally, thermally metamorphosed the serpentinite. The formation of bastites after talc, tremolite and anthophyllite demonstrates that serpentinization is a multi-stage process. Subsequently, carbonate minerals were formed.
