Abstract: In this study, it was attempted to determine the petrochcmistry and parent rock characteristics of theGümüşler amphibolites, associatcd with marble and quartzite, from the Niğde metamorplıics by using tlıcirwhole-rock chemical analyses. Amphibolites are associated with a seri es of Pre-Cretaceous supracmstalmetasediınents of the Gümüşler Formation. Massive and variably foliated amphibolites are made up mainlyby plagioclase, hornblende, quartz, diopsite witlı accessory sphene and apatite. Based on trace elementcharacteristics, the amphibolites are suggested to be metaigneous roeks; tuff or less likely basaltic-andesiticlava/sili, which were emplaced between metasediınents. Their parent roeks are subalkalinc basalt andandesite in cnmposition, and are characterisedby high K₂O, Rb, Sr, Ba, K/Rb (-270-550) ratin, and low MgO,Ti,Y, Zr, CaO/Al₂O₃ ratio. Pctrochenıical dataalso suggcstthat the parent roeks of these orthoaınphiboliteswere possibly fonued by fraetionalcrystallization of olivine, clinopyroxene and hornblende.
