The Provenance of Rutile in the Metamorphic Rocks from Çîniyeri-Kure (Menderes Massif) Area and Rutile Contents of Fluvial Sediments

Abstract: The studied area is located between Çiniyeri and Küre of Menderes Massif at the East of Tire (Izmir), Inthe region metamoiphic units belong to Menderes Massif which have been locally intercepted by numerous quartz veinsare arranged in an ascending order as augen gneiss, kyanite-garnet schists, garnet-mica schists and marbles, THe pétrographie and chemical studies show that kyanite-garnet schists and quartz veins are important source rocks for rutile deposits in detritical sediments. Rutiles in high grade metamorphic rocks have metamorphic origin rather than detriücal andfonns as a function of oxygen pressure and chemical composition of rock.Garnets and rutiles seem to from an important plrt of heavy mineral concentrations. Rutile in the sediments of theinvestigated area is generally most abundant in the -0.149+0.077 mm fraction with an average 1,33 percent, The totalproven reserves for all grain size fractions are detemiined to be 2 million metric tons. The detailed grain size analysisr applied to the fluvial originated sediments indicate that the material used should be considered as coarse sand size.
