Comparison of two different ophiolite districts in terms of some soil physical properties of grounds

Abstract

In this study, some physical characteristics of the soils formed on the metamorphic soleand the mantle section of the ophiolitic sequence which is represented by ultramaficcumulates and tectonites located in Karacasu district in Kahramanmaraş and formed onthe crustal rocks which are located around Göksun-Elbistan towns to the north ofKahramanmaraş, were investigated. In order to correlate the soil properties with thebedrocks from the different parts of the ophiolite, rock samples were collected from thesame locations with 18 surface soil samples. Field capacity, permanent wilting point,liquid limit, plastic limit, coefficient of linear extensibility and volumetric shrinkage testswere performed on the soil samples. The crustal section is represented by the threedifferent rock groups such as: cumulate gabbro (amphibole gabbro, olivine gabbro andgabbro), isotropic gabbro (gabbro) and sheeted dike complex (diabase). According toindependent “t test” results; the physical properties of two fields were different fromeach other, except for the linear extension coefficient, (P
