Barite deposits in
the region of Şarkikaraağaç and Hüyük which are generally located in the form
of veins, lenses and layers along the contacts of these units and the schists
showing an extensive distribution within the same formation found within
recrystallized Çaltepe limestone and dolomite, Çavuştepe calcschists of the Cambrian-Devonian
age Sultandede formation are epigenetic in character. According to the results
of chemical analysis of barite mineralization in the region, the presence of
trace elements such as Pb, Zn, Cu, Cd, Ni, Co, Ag, Sb are locally identified in
low values within barites of the region. Especially, in some trace elements
such as Pb, Zn, Cu, Cd, Ag and As show an increase towards from Hüyük region to
Çarıksaraylar area. When the results of chemical analysis of barite samples
evaluated statistically, the presence of high correlation between Ba-Pb, Ba- Ag.
Pb-Ag, and AI2O3-K2O element pairs and
mediumgrade correlation between Ba-Sr, Pb-Cu, Zn-Cd, CaOFe 2O3, CaO-SiO2, SiO2-AI2O3, CO- MgO, Fe2O3-AI2O3, Fe2O3, Fe2O3-Na2O, MgO-K2O element pairs of
barite ores have been determined. The deposition forms of the barites in the
investigated area, paragenesis, wall rock alteration, the high amount of trace
elements, high Ba/Sr ratio, SrO values over 1.5 %, 180°-360°C homogenisation temperatures
of the two-phase (liquid+gas) fluid inclusions, +30.15 %o and +13.9 %o 34S isotope ratio in
galena and barites, and 434°C high formation temperature indicate a
hydrothermal origin of barite deposits in the region.
