Prediction of weathering development in metarhyolites of the Ilgın (Konya) area, SW Turkey

Fresh to weathered metarhyolites crop out in the Ilgın (Konya) area of the Afyon-Bolkardağ Zone. Determination of the development of weathering was studied by physical (i.e. specific gravity, dry unit weight, saturated unit weight, porosity, void ratio, and degree of saturation by weight) and mechanical (i.e. point load) properties and the “point rock change value” (RCVp ) and “point rock change ratio” (RCRp ) values of the metarhyolite rock samples.
