| Popis: | The study area is surrounded by Alacahan, Çetinkaya, Kangal and their vicinity where there are allocthonous and autocthonous rock types. As a result of this study, the metamorphic units studied have been classified as formation and member, and so incorporated into Bolkardağı nappe. Bolkardağı nappe, which passed metamorphism as greenschist facies was deposited between the Late Devonian and the Late Cretaceous. From bottom to top, it is discriminated as the Late Devonian Düzce formation, the Carboniferous Kınalar formation, the Late Permian Çayderesi formation, (?)the Middle-Late Triassic-Cretaceous Kayaköy formation and the Late Cretaceous Karaböğürtlen formation. Meta-quartzites at the base of Kınalar formation were identified as Bakırtepe member and meta-conglomerates at the base of Karaböğürtlen formation were identified as metaçakıltaşı member. Bolkardağı nappe which shows imbricated structures within are tectonically overlied by Munzur nappe and Güneş Ophiolite. On the other hand, Hekimhan formation, Kangal formation, Yamadağ group volcanics and Quaternary units overlie Bolkardağı nappe with an angular discordance |
