As a very important textural characteristic, grain size has been widely used by geologists to determine the distance a piece of sediment must have taken before coming to a halt.Sediments,be they clastic or chemical, is determined by their methods of erosion. Clastic sediments being broken down through physical means like water, wind, ice by abrasion. These may give rise to pebbles/gravels,sand,silt and clays.So,to interpret the geomorphological settings of the Çiftlik Basin(paleo or present);sediments must have either been transported from regional to local settings or from within the local settings.Natural characteristics of sediments with recognized grain size composition have been classified using the Udden-Wentworth  grain size scale(phi= ?).This is the method that facilitates statistical analysis, graphical representation and geological representation of terrestrial sediments of Oval?ba?, Melendiz and Imamhatip of the Çiftlik Basin. A total of 158 samples were investigated and detailed grain size analysis were done on 41 selected samples. The Oval?ba? (750 cm) OVA1 to OVA15 samples, Melendiz (661 cm) MEL1 to MEL10 samples and Imamhatip (860 cm) IMA1 to IMA 16 samples. The Phi (?) values ranges from ?= -3 to ?=5; from very coarse to very fine grains. Most of the grain sizes were coarse skewed and very poorly sorted, indicative of intra-locality origin of most of the sediments. Skewness which is the measure of symmetry and can either be positive (fine), negative (coarse) or symmetrical. The grain-sizes used are as follows;? 0.062mm(?=5)clays and muds,0.062mm(?=4) silt,0.125mm(?=3)fine sand,0.25mm(?=2)medium sand,0.5mm(?=1)coarse sand,1mm(?=0)very coarse sand,?2mm(?=-1)granules,4mm(?=-2)gravels,8mm(?=-3) pebbles. Their sorting results are as follows; very poorly sorted=7 samples and poorly sorted =34 samples while their skewness is; very fine skew=10 samples, coarse skew=3 samples and very coarse skew=28 samples.
