==Geology== Late created formations around İzmir consist of sandstone, shale and limestone blocks some of which may be larger than several kilometers. Such formations which are generally observed on hills around the region, are the main reasons for resistance on the hills. In addition to these, the community of neogen age can easily be estimated through the andesitic compounds of volcanic origin, around Mount Yamanlar. Such units can be listed as silicon, aluminum, sodium, lava with magnesium content, tuff and tuff stuffed lava agglomerates. The lava also contains reddish brown and greenish gray large feldspar crystals. Neogen sedimentary rocks are made up of clay stone, sandstone and pebble stones at dept while being made up only of limestone on the top. At some places clay stone is observed on limestone layers. It is possible to say that ground resistance is satisfactory in regions covered with limestone on top, while ground resistance is low in regions which has thin layers of limestone intercalated with mud rocks.
