2). In general, the discriminations between 
Quarternary volcanic materials and older Tertiary 
sedimentary rocks can easily be determined using these 
image processing techniques. These methods proved 
capable of discriminating four volcanic materials and 
nine different sedimentary rocks based on their 
terrain characteristics and their processed image 
characteristics.
