Petrographical and Chemical-Mineralogical Characteristics ofCefaîıkdağ and Baranadağ Platans (Kaman)

ABSTRAC : Major and some trace element chemical analyses have made, for 12 samples belonging to Cefahkdağ and Ba.ran.adag Pinions, and these piétons, are placed in `the central part, of Middle- AnadoHa granitoid belt, In these phuons» two petrograpMcal rock. groups aie determined» according to petiograpldcal and chemical-mineralogical characteristics. These are .subalkaltne and alkaline groups which belonging, to cafemic associations and show metaluminous characteristic. Subalkaline rocks,, which have monzonitic composition.» like "minimum melt-I type", and alkaline rocks which have syenitic composition» like "A type" granitoid. Both of two petrographical groups derived from, different magmatic melting which occuied partial melting, of the same source material (crosn-mantel) in, two different stage.
