Geocache Description:

Hot springs in Balçova / Yaylar Balçova sicak

Turkey is located just north of the boundary between two tectonic plates. The African plate in the south and the Eurasian in the north.
These plates moves against each other. The Eurasian plate slides up on the African. In this way, the Turkish highlands, Anatolian, with the Taurus Mountains (Toro Daglari) in the South and the Pontic Mountains (Kuzey Anadolu Daglari) in the North, was created.
A proof that this process is still ongoing is the recurring earthquakes in the area.
In this process the continental crust is "harmed" so that the hot layer that is below the earth's crust, the mantle, comes closer to the surface and get access to more shallow layers through cracks in the crust.
The outermost layer of the mantle has a temperature of 500-900 °C.
The groundwater in this area comes from the mountainous area that rises right behind Balcova.
As the water is filtered through layers of soil it is purified and at the same time it takes up minerals and salts.
The water drains through the ground, that is heated by the underlying mantle, and the water is heated.

The water in some wells is warmer then 100 °C. The reason this is possible is that the boiling point increases with pressure. Greater depth gives higher pressure and higher potential temperature of the water.
Groundwater in this area is to be found at 60-70m depth. But the springs and wells are deeper than that.

The hot springs waters have been regarded as curative since ancient time.
According to the Greek mythology / history. Here Agamemnon, the commander of the Greek army, and his men healed their wounds after the victory in the Trojan War. Ca. 1184 BC.

When arrived at the coordinates you will stand in front of a ”structure” where steam is coming out. It smells rotten eggs. The smell is not sulfur (S) as sulfur in its pure form does not smell. The smell is hydrogen sulfide (H2S) as it arises via the hydrolysis of sulfide minerals.
This is the only place where you can smell the spring water, as the water is pumped up in pipes, cooled down and treated before it is used

My question is: How is it that these hot springs contain more salts and minerals than common ground water?

In order to log this cache you have to:

Walk down to the Balçova Termal entrance (125m. West) and take a nice picture of yourself standing on the storm water drain.
Mail me the exact coordinates of the storm water drain and the answer for the question.
Submit the picture in the log, after received my reply.

The concentration of minerals and salts in the water vary between the different sources. (Mineral ve tuzlari suya konsantrasyonu farkli kaynaklardan arasinda degismektedir.)	mg/liter (g/m²)
K+ (Kalium/ Potassium)	2.4 - 28.4
Na+ (Natrium)	115 - 420
NH4+ (Ammonium)	0.1 - 0.61
Ca++ (Calcium)	16.1 - 72.7
Mg++ (Magnesium)	1.36 - 20.1
Fe (Iron)	0.1
As (Arsenic)	0.03 - 0.48
B (Boron)	3.1 - 12.6
Li+ (Lithium)	0.4 - 1.6
SiO2 (Silicon dioxide/Silica)	26 - 60
HCO3- (Bicarbonate)	353 - 695
CO3- (Carbon trioxide)	0 - 64
SO4- (Sulfate)	165 - 95.5
Cl- (Chlorine)	64.9 - 231
S- - (Sulfur)	0.1
NO2- (Nitrite)	0.01
NO3 - (Nitrate)	0,2 - 4.2
PO4 - - - (Phosphate)	0.01
pH	8.16 - 8.87

You can see several small green sheds scattered around in the area in where the water is brought up.

Balçova Termal is a Treatment Center where the water is used in hydrotherapy.

Its also used for heating some apartment in the area and for hot tap-water after its cooled down and chlorinated.

Benim sorum: Bu kaplicalar daha fazla tuz ve ortak bir zemin sudan daha mineraller içerir o nasil?

Amaciyla zorunda bu önbellek günlügüne:

1. Balçova Termal giris (125m. Bati) asagi yürüyün ve yagmur suyu drenaj kendinizi ayakta güzel bir resim çekmek.

2. Mail bana kesin yagmur suyu drenaj ve soru için cevap koordinatlari.

3. Benim cevap aldiktan sonra, günlügüne resim gönderin

The storm water drain (Yagmur suyu drenaj)

Türkiye'nin hemen kuzeyinde iki tektonik plakalar arasinda sinir bulunmaktadir. Güneyde Afrika levhasinin ve kuzeyde Avrasya. Bu birbirlerine karsi hamle plakalar. Kadar Afrika üzerinde Avrasya levhasi slaytlar. Bu sekilde, Güney ve Kuzey Anadolu Daglari olarak Toro Daglari ile Türk daglik, Anadolu, olusturuldu.Bu süreç hala devam etmekte oldugunu bir kaniti bölgede tekrarlayan deprem oldugunu.

Bu süreçte kita kabugunun yer kabugu, manto altinda sicak tabaka, yüzeye yakin geliyor ki ve kabugunda çatlaklar yoluyla daha sig katmanlara erisim "zarar" dir.
Manto dis tabakasi genellikle 5-900 bir sicakligi °C.
Bu alanda yeralti Balçova hemen arkasinda yükselen daglik bölgeden geliyor.
suyun aritilarak toprak katmanlari üzerinden ve mineral ve tuzlari alir ayni anda süzülür gibi.
Su altinda yatan manto ve su i isitmali tarafindan isitilan zemin üzerinden kuruyor.

Bazi kuyularda su daha sonra 100 sicaktir °C. Bu mümkün nedeni basinç ile kaynama noktasi artar.Daha derin daha yüksek basinç ve su daha yüksek potansiyel sicaklik verir.
Bu alanda yeraltisuyu 60-70m derin bulmaktir. Ama yaylar ve kuyular çok daha derin.

Kaplica sulari eski zamandan beri tedavi edici olarak kabul edilmistir.
Yunan mitolojisinde / tarihine göre. Burada Agamemnon, Yunan ordusunun komutani ve adamlari Truva Savasi'nin zaferinden sonra onlarin yaralari iyilesti. Ca. 1184 BC Vardigimizda seni buhar çikan bir "yapi" önünde duracak koordinatlar. O çürük yumurta kokuyor.koku yok saf bir sekilde kükürt gibi kokusu (S) kükürt degildir.
O sülfit minerallerinin hidroliz yoluyla ortaya çikar gibi koku hidrojen sülfür (H2S) 'dir.

Su soguduktan, borular içinde pompalanir olarak kullanilmadan önce tedavi Bu, kaynak suyu kokusunu alabiliyorum tek yerdir.
