Abstract	Weathering and hydrothermal alteration of the granitic rocks in the Eastern Black Sea Region (NE Turkey) are important phenomena affecting the engineering projects in the region. The study investigated the probable paths of rock-forming mineral transformations due to weathering in the Harsit granitoid rocks, the changes of the major oxides as a consequence of weathering and the effects of weathering on the engineering properties. To identify the changes in the major oxides, the volume concentrations were considered in relation to the dry density. Chemical leaching during weathering was shown to be significant in changing the minerals. It was concluded that the engineering properties of the weathered granitic rocks can be most reliably predicted by P-wave velocity.Les altérations météoriques et hydrothermales de roches granitiques dans la région de la Mer Noire orientale (NE de la Turquie) jouent un rôle notable dans les projets d’ingénierie de cette région. L’étude a concerné les modes de transformations minèralogiques et l’évolution des principaux oxydes rèsultant de l’altération météorique des roches granitoïdes de Harsit, ainsi que les effets de ces transformations sur les propriétés géotechniques de ces roches. Pour suivre l’évolution des principaux oxydes, leurs concentrations volumiques ont été analysées en fonction de la densité sèche des matériaux. Le rôle de la lixiviation pendant l’altération a été souligné comme facteur important de l’évolution minéralogique. De plus, il a été montré que les propriétés géotechniques des roches granitiques altérées pouvaient être prédites de façon assez fiable par les vitesses de propagation des ondes P.
