ABSTRACT

Host rock of magnesite occurrences in three areas (Süleymaniye, Margı, Tutluca) are the altered peridotite which on the northernmost outcrops of the İzmir-Ankra suture zone. Magnesite is formed in the cracks and fractures of highly altered harzburgite in these three areas. Chrysotile and lizardite are the abundant serpentinite mineral and orthopyroxene, olivine, magnetite, talc, brucite and chromite consist of these rocks which have mesh to hourglass texture. Source of Mg⁺² for magnesite formation is coming from serpentinite. During serpentinization processes H₂O and CO₂ input mineralogic structure and form mineral transform. H₂O content in system increases, MgO, CaO and SiO₂ content decreases because of remove the systems. According to mineralogic association serpentinization of harzburgite occurs low temperature below 350℃ and represents the open system serpentinization condition. These rocks show positive La, Nd, Eu, Ho, Tm, Lu anomalies but negative Ce, Pr, Sm, Gd, Er, Yb anomalies to chondrite/normalize diagram. REE content of serpentinite are consumed according to chondrite. According to mineralogical and geochemical properties is these rock related to the SSZ type ophiolities.
