ABSTRACT
Rocks under weathering effects have varying properties which mostly weaken rock material and consequently the rock mass. The degree and depth of weathering should be investigated in order to identify the engineering properties and the change of these properties with varying weathering grades. Due to the disadvantages of field studies on ultramafic rocks from the view of weathering properties and the difficulties of sample preparation for laboratory studies there exist a lack on the properties of weathering of ultramafic rocks in the literature. In this study, ultramafic and mafic rocks exposed in BursaOrhaneli region were investigated from the view of weathering.
