Abstract

Bu çalışmada Uşak İlinde bulunan Kayaağıl ve
Karaağaç köyleri çevresinin hidrojeolojisi ve bölgede yer alan sıcak - soğuk
suların hidrojeokimyasal özellikleri incelenmiştir. İnceleme alanının temelinde
yer alan Paleozoyik yaşlı Eşme formasyonunu oluşturan şistler ve şistler
içerisindeki mermer bantları hidrotermal sistemin ana
hazne kayacını, Tersiyer ve Kuvaterner yaşlı birimlerin geçirimsiz seviyeleri
örtü kayacı, faylanma ile gelişen kırık hatları ise akışkanları yüzeye taşıyan
akım yollarını oluşturmaktadır. Bölgede derinlere süzülen yeraltısuları, jeotermik
gradyana bağlı olarak ısınmaktadır. İnceleme
alanında termal
suların Na-HCO₃ , soğuk suların Ca-Mg-HCO₃, karışım sularının
ise Ca-Mg-SO₄-HCO₃'lı sular
fasiyesinde olduğu tespit edilmiştir. Termal sularda Na artışı suların sıcaklığı
ve kaya-su etkileşim sürecine bağlıdır. Kayaağıl termal
suyu albit, analsim, aragonit, kalsit, barit, kalsedon, kristobalit, dolomit,
florit, jipsit, kuvars ve sanidin minerallerine doygundur. Termal suların silis
jeotermometrelerine göre hesaplanan hazne kaya sıcaklıkları 102-147 ⁰C
arasındadır. Ayrıca, yeraltısularının Al, As, B, Fe, Cd, Cr, Mn, Ni ve Pb gibi
ağır metal içerikleri incelenmiştir. Termal ve karışım sularında As artışı
suyun sıcaklığı ile doğru orantılıdır. Soğuk sulardaki As artışının kaynak
sularının etkileşim halinde bulunduğu volkanik kayaçlar ile ilişkili olarak
kaya-su etkileşiminde kaynaklandığı düşünülmektedir. Sularda tespit edilen
ekstrem Al ve Mn değerleri antropojenik kökenli faaliyetlerden
kaynaklanmaktadır.

Hydrogeological and Hydrogeochemical Investigation of Kayaağıl (Uşak) Thermal Waters

Abstract

In this study, hydrogeology of Kayaağıl and Karaağaç villages in Uşak province and hydrogeochemical properties of
thermal and cold waters were investigated. The Paleozoic aged Eşme formation which are formed from schists and
marble bands is the main reservoir rocks of the hydrothermal system, the impermeable levels of the Tertiary and
Quaternary units constitute the cover rocks and the fracture lines developed by the faulting are the flow paths carrying
the fluids to the surface. Groundwater infiltrating to deep in the region heat due to the geothermal gradient. In the
study area, it was determined that the thermal waters are Na-HCO3, the cold waters Ca-Mg-HCO3 and the mixed
waters are Ca-Mg-SO4-HCO3 waters. The increase of Na in the thermal waters depends on the water temperature
and the rock-water interaction process. Kayaağıl thermal water is saturated with albite, analsim, aragonite, calcite, barite, calcite, cristobalite, dolomite, fluorite, gypsum, quartz and sanidine minerals. The reservoir temperatures of
the thermal waters are calculated as 102-1470C according to the silica geothermometers. In addition, trace metal
contents of groundwater such as Al, As, B, Fe, Cd, Cr, Mn, Ni and Pb were also researched. The increase of As in
the thermal and mixture waters is directly proportional to the water temperature. The increase of As in the cold waters
originated from water-rock interaction. The high Al and Mn values of water are due to the anthropogenic activities.
