Özet:

 


As result of geologic studies on
the field and microscopic studies of the samples from Altıntepe and Çilektepe
areas located southwest of Sancaklı village, Karşıyaka-İzmir, dacitic tuffs and
lavas and their silicified types, biotite-hornblend-dacite. andesitic lava,
tuff and agglomeras in addition to andesitic dykes are determined and mapped.
Investigations indicate two different type of mineralizations, First type is
gold and silver mineralizations in quartz veins emplaced in tension fractures
of silicified dacitic lavas at Altıntepe (Arapdağ) sector. The other kind of
mineralizations is related to hydrothermal alterations in dacitic tuffs at
Çilektepe (Çerkeskayası or Pilavtepe) sector. Gold mineralizations are
developed as stockworks and disseminations in those kind of rocks because
uprising channels are tapped by silica gels. The age of volcanism based on
regional geological data is between Late Oligocene and Middle Miocene.
Biotite-hornblende-dacites (14.7+0.5 Ma) contain no precious metal mineralizations
and are believed to occur after ore mineralizations. According to these
findings, the mineralizations should be Middle Miocene in age.
