Abstract: The Tekirova Ophiolite Nappe, part of the Antalya Unit in the southwest Anatolia, consists of a dismemberedoceanic crust sequence with tectonic slices in different sizes. Three types of subsequent mineralizationsare present in the ophiolitic rocks during the oceanic crust formation, emplacement and post-emplacement, respectively. First stage, pyrometamorphism (pyrometasomatization) caused to occurrenceof metamorphic minerals such as scapolite, diopside, garnet, epidote and tremolite. Second stage,hydrothermal metamorphism(alteration)is represented byserpentinization of ultramafic rocks. Third stageis followed by listwaenite formation, and age neoformation and/or alteration products contain carbonates(calcite, dolomite, aragonite, magnesite, hydromagnesite, hydrotalcite), oxides and hydroxides (brucite,goethite, hematite), phyllosilicates (smectite, illite, chlorite, talc, C-V, C-S, I-S) and quartz. The serpentineminerals can be distinguished from each other by morphology: ribbon-like shapes for antigorite, platy forlizardite and fibrous for chrysotile. Serpentines are represented by three polytypes as structural groups ofA- (clinochrysotile-2M1), C- (lizardite-1T) and D- (lizardite-2H1). Chondrite-normalized trace and rareearth element patterns of 1T and 2H1 Fe-lizardites, Fe-tremolite and Ca-hydromagnesite minerals showsimilar trends indicating similar ophioliticparent rocks and differentiated form each others. The δ18O andδD values of serpentines indicate two different serpantinization under hypogene conditions as oceanic(lizardite-1T) and supergene as Alpin types (clinochrysotile-2M1 and lizardite-2H1) at temperatures ofabout 200 °C and 100 °C, respectively.
