Karşıyaka is a district of İzmir Province in Turkey. The district extends for twelve kilometres along the northern and eastern coastline of the tip of the Gulf of İzmir. Its centre is at a distance of 6 km to the north from the traditional centre of İzmir, which is Konak Square in Konak at the opposite coast. Karşıyaka's district area neighbours the district areas of Menemen to the north, Bornova to the east and Çiğli to the west. Besides being an active venue of commerce, culture and educational actitivies and tourism, Karşıyaka also has an urban culture centred on the sports club Karşıyaka SK, which commands a large and passionate fan base.

Late created formations around Izmir 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 silisium,
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.
