ABSTRACT: Block marble productions are made at fourdifferent stratigraphie level having differenttexture, colour and pattern in the Muğla region..These marble levels from bottom to* top arePermocarbonifereous aged- banded and lensshaped white marbles interbedded with the same`aged phyllites, Trias aged white marbles found aslenses within schists with different hue and paiiem.Upper Cretaceous aged emery bearing white -greyish while marbles and. Paleocene aged redcoloured Aegean Bordeaux Marble. In this paperthe mineralogicaltchemicalt physical andmechanical properties of the marble samplesobtained from the working quarries opened atdifferent stratigraphie levels were determined andthe inie dations of these roperties wereinvestigated. The Muğla region marbles, generally have lowporosity, high unii weight and are highly strongrocks having mineral sizes vary between 22ß and769 ft As the mineral sizes increasef the uniaxialcompressive strength, point load strength index,.flexural strength and Böhme surface attritionvalues,. Schmidt Hammer values and dry unitweight are found to decrease and as the dry unitweight increases the uniaxial compressivestrength,, point load strength index., flexural.strength, Böhme surface attrition value, Shorehardness index and Schmidt hammer values arefound to increase. The ratio between the uniaxialuniaxial. compressive strength (GC) and the pointload strength index (Isc50) of the Mugla marblesis found to vaty between 15 and 26 and the meanrelation is found to be represented by dc= 14„24lsc+32.
