Geology of Metaophiolite at Kazdağ Massive (Balıkesir) and the Its Evaluation in Terms of Titanium Content

ABSTRACT: In this study, stratigraphical position of metaophiolite (metadunite, amphibolite/metagabbro) of Kazdağ Massive (Balıkesir) is determined and they are examined for their titanium contents. Metaophiolite in Kazdağ Massive, composed of high-degree metamorphic rocks (amphibolite facies), are called as Tozlu Formation. This unit contains metadunites, amphibolites and metaperidotites and overlain by Fındıklı Formation, composed of amphibole gneiss and marble sequence, with a tectonic contact. Sarıkız Formation which is formed by marbles, comes over Tozlu Formation with a conformable boundary and overlain by Sütüven Formation, which is dominantly composed of gneisses. Titanium ores have primary and secondary bedding types. The important rock types for the primary beddings are anorthosite, gabbro and norite. The source of amphibolites in Tozlu Formation is originated from gabbroic rocks on the bases of fieldwork and mineralogical – petrographical methods. Under this scope, ore microscopy of samples are studied. In addition, in order to obtain the titanium content in the study area 23 samples are objected to chemical analyses. The result of these analyses and the relationship of titanium with other elements; Fe, Co, Cr, Ni, Cu and Zn; are discussed and evaluated. As a result of mineralogical and petrographical studies and chemical analyses, the area of Kazdağ metaophiolite do not seem encouraging for titanium mineralization under today’s conditions.
