      Rapakivi texture is seen mainly in quartz monzonite of Akapol area which is investigated based on petrography studies. In all investigated rapakivi textures, alkali feldspar owned rounded margins; which is surrounded by Plagioclase .
   Existing of microgranoular enclaves mafic, poikilitic texture, sieve texture in plagioclases and also rapakivi texture are evidences of the magma mixing.
