Özet
The objective of this study is to investigate the petrography and geochemistry of the Gumusler (Nigde) area gneisses and amphibolites, Central Turkey. Amphibolites and gneisses are commonly very difficult to determine in areas whether sedimentary or igneous origin. The Gumusler rocks are interpreted to be of igneous origin based up on Niggli trends and trace element characteristics. The gneisses were mainly calc-alkaline whereas amphibolites were mainly tholeiitic in character, and both of them reflect volcanic are setting precursor. Field relationships and chemical data suggest that the amphibolites formed as metamorhism of basic tuff wheras gneisses likely from acidic tuff and related rocks.
