Abstract: In this study, mineralogy, petrography and geochemistry of gabbros, from Northeast ofKaman Region (Kırşehir), were investigated. Gabbros generally consist of plagioclase, hornblende, augiteand rarely olivine. Chlorite, tremolite, calcite, quartz, albite, epidote and biotite are observed as alterationminerals. The accessory minerals are magnetite, ilmenite, hematite and pyrite as opaque minerals, andalso sphene and apatite. Generally, rocks are defined as hornblende-gabbro or fine grained-gabbro. According to chemical analyses results, gabbros are crystallized from subalkaline tholeiitic type of magmaand these gabbros may represent a member of an ophiolitic sequence.
