Comprising a sulfurous zone made
up of marcasite+pyrite+hematite+goethite+boehmite+diasporite+anatase+gypsurn
minerals at its base, Doğankuzu-Mortaş Bauxite ore bed locates at the
discordance zone between Cenomanian and Santonian limestones of Cretaceous.
Pisolithic ore bed, including locally calcareous conglomeratic lenticules sits
on the sulfurous and lesser one-con taining level and where the ore bed is
thickening, that conglomeratic zones represent the paleodolines. Toward the
upper parts the quality of ore increases and a massive blockage is seen. At
uppermost part, a sulfuric zone, that of a few centimeters thick covers the ore
and the pyrite-bearing clayev carbonates capping those, grades upward to the
Santonian limestones. In these two ore beds, veins, bluish gray and green
coloured, including marcasite and pyrite at 15 percent and thickening up to two
meters, rich in diaspore, are seen and those are crackfills. These extend into
neither underneath nor covering limestones Petrographical and mineralogical
findings show that, especially through internal diagenesis reductive processes
were effective and an explanation for the formation of sulfurous zones is that
the sulfates in the sea water penetrate into the bauxitic matter and being to
the sulfures by the bacteria, synchronously to the deposition of Santonian
carbonates.
