Kuşadası Körfezi Pamucak plajlarının (Batı Türkiye) sedimantolojik ve mineralojik özellikleri
Özet
The main purpose of this thesis work is to investigate textural and mineralogical characteristics ofsediments in detail and factors controlling marine hydrodynamic and terrestrial geological effects atPamucak and Davutlar beaches where Küçük Menderes River enters the Aegean Sea. İn this contextsediments were collected at a total of 42 sampling stations from shoreline and backshore areas of thePamucak and Davutlar beaches. Sediment samples were then subjected to grain size, heavy mineral andgeochemical multielement analysis.Fine-to medium-sand is the dominant grain size of beach sediments and differences in mean grain size,sorting, skewness and kurtosis can be explaned by regional varying hydrodynamic and river inputconditons.Heavy mineral contents of sediments were generally high and varied between 0,8 and 75 %. Heavymineral fractions contained 5-20 % opaque minerals. Other minerals with abundances of between 5 and20 were almandine, pyrope, grossular, sillimanite, staurolite, rutile, epidote, zoisite, augite, diopside,hypersthene, tremolite, actinolite, horblende, glaucophane, muscovite, biotite, chlorite, tourmaline,sphene, disthene. Mineral distribution suggests that metamorphic Menderes Masif is the importantterrestrial geological source. Occurrences of high biotite contents along the wawe marks indicate thatgrains are transported not only through rolling but also lateral sliding on waves. The concentrations of Ti(<3.08 %), Fe (<16,45 %) and Mn (< 6346 ppm) when compared with average sandstones are relativelyhigh and this data can be used for ore-mineral exploration on land.
