The objective of this study is to
determine the source, chemical characteristics and isotopic components of the
İspendere mineral and thermal waters, Malatya, Turkey. There are many mineral and
thermal water springs in the area with fl ow rates ranging between 0.01 – 0.4
l/s. Geochemical and isotope chemistry studies were carried out at three
different thermal springs in the region as well as three different cold water
springs during May-October 2011. The temperature of mineral and thermal waters
were measured as between 21.1°C – 23.6°C in May 2011 and as 20.8°C in October
2011. The region was determined as a low temperature geothermal area and the
reason for this is thought to be cold water mixing. The pH values of mineral
and thermal spring waters were measured to be between 6.19 –6.69, EC values
were measured to be between 1420 μS/cm and 2720 μS/cm, pH values of shallow and
deep wells ranged between 6.04 and 7.82, whereas EC values were measured
approximately between 275 μS/cm and 3300 μS/cm. The MgHCO3 water type dominates
the chemistry of mineral and thermal water in study area. The results of 18O
and 2H isotope analysis yield that the springs of mineral and
thermal waters as well as cold waters are fed by meteoric rains. It was
determined that the İspendere mineral and thermal waters have low tritium (³H),
low Cl and high EC values. Reservoir rock temperatures have been estimated to
be between 95 -132°C as a result of the quartz geo-thermometer calculations.
