Abstract: The Yuvaköy neigbourhood is an area where Ankara-Çankırı ophiolite crops out. Yuvaköy ophiolite consists ofascending formations of tectonic complex, volcanic-sedimentary sequence, tectonites and cumulates. These unitsare covered byCretaceous and Tertiary sedimentary units. Miocene volcanics are represented by Tekke volcanics.The examined field is a tectonic complex containing heterogenous harzburgite, gabbro, diabase, basalt,radiolarite and limestone blcoks. Tectonites are represented by serpentinized harzburgites. Volcanic andsedimentary sequences comprise basalt, radiolarite, and limestone in chert alternations. The Tekke volcanics arecomprised of andesitic lava, agglomerate and tuffs.Results of chemical analyses showed that the diabase dikes are tholeiitic and the basalts are alkaline incharacter. The andesites of the Tekke volkanics are of intermediate, sub-alkaline character and are andesiticdacitic compositions.Harzburgites underwent serpentinization to an advanced level . Such a transformation results from the factthat the area has been subjected to a low-medium grade metamorphism of greenschist facies conditions. Thisstudydetermined that the basaltic rocks were spilitized due to the effect of metasomatism. Chemichal Alteration Index(CIA) values indicated that the rocks in the area underwent chemical alteration at the beginning stages of themedium zone.The outcrops in the units in the studied are, bear traces of Alpine Orogenic Movements. Deformationstructures occurred during and aftersettlement in the studied area, and these are observed as overthrust faults.
