Liecive Piestany
Piestany su svetoznamym kupelnym mestom hlavne vdaka termalnemu bohatstvu z hlbok Zeme. Pre vznik, vyskyt a chemicke zlozenie termalnych pramenov v Piestanoch ma rozhodujuci vyznam geologicka skladba Povazskeho Inovca, ktory tvori infiltracnu oblast tychto zriediel. Jeho krystalicke jadro tvoria zuly a ruly v centre pohoria, ktore je dalej pokryte druhohornymi vrstvami. Z hladiska vyskytu termalnych vod su dolezite predovsetkym dolomity, vapence a dolomiticke vapence juhozapadnych svahov Inovca.
Zrazkova voda, ktora vsakuje dobre priepustnymi vapencovo-dolomitickymi suvrstvami tohto pohoria az do hlbok okolo 2000 metrov, sa v tychto horninach mineralizuje a prehrieva zemskym teplom. Po tektonickych poruchach, ktore kedysi vznikli v miestach dnesnych vyverov, vystupuje horuca mineralizovana voda na povrch, v priestore medzi lavym brehom Vahu a mrtvym obtokovym ramenom, kde vyviera vacsina termalnych pramenov. Tie su 50 az 60 metrov pod povrchom odborne zachytene, aby nedoslo k miesaniu s podpovrchovymi vodami. Uhrnna kapacita zachytenych zriediel je viac ako 3 miliony litrov vody za den. Obsahuju okolo 1500 mg mineralnych latok na liter vody, a volne plyny - najma sirovodik. Mineralne pramene su sirnato-hydrouhlicitanove, vapenato-horcikove, sirne, hypotonicke termy s prevladajucim obsahom kationov Ca, Mg, Na a anionov SO4, HCO3, Cl a H2S.
Druhym prirodnym liecivym zdrojom, ktory sa tazi z obtokoveho ramena Vahu, na dne ktoreho vyvieraju sirove pramene, je sirne termalne bahno. Toto bahno patri medzi najliecivejsie peloidy (pelos – grecky hlina) na svete. Peloidy su * procesmi, za posobenia *, vzniknute prirodne latky, ktore sa pouzivaju na prevenciu a liecbu prevazne reumatickych ochoreni. Su to male gulate, gulovite, alebo elipsovite kryptokrystalicke uhlikove zoskupenia zvycajne bez vnutornej struktury. Tieto zhluky su velke od 20 do 100 µm, no zriedka sa vyskytuju az vo velkosti 500 µm. Vyskytuju sa prevazne v pritomnosti termalnych pramenov.
Vasou ulohou je:
1. Odfotit pramen liecivej termalnej vody – tzv. “vajcovky“ a foto prilozit k logu. (Na Kupelnom ostrove su minimalne 3 verejne pristupne miesta)
+ zaslat odpoved na nasledujuce otazky mailom na GeoKlipo(zavinac)gmail.com:
2. Aka je teplota (z hlbin Zeme) vyvierajuceho termalneho pramena (tolerancia ± 3°C).
3. Vysvetlit ako vznikaju peloidy.
4. Vymenovat aspon dvoje dalsie kupele na Slovensku kde sa pouzivaju peloidy na balneoterapeuticke ucely.
Pozor pri otazke c. 2. Pitny pramen nerovna sa pramen vyvierajuci zo Zeme. Teplota, ktora je vytesana na jednom z pitnych pramenov nie je spravna odpoved (ani v ramci tolerancie).
Cache logujte az po potvrdeni spravnosti odpovedi. Ak svoju navstevu chcete zalogovat ihned, pouzite “Write note”. Po potvrdeni mozete zmenit na “Found it”.
Healing Piestany
Piestany is world famous city thanks to thermal resources from depth of the Earth. Geological composition of Povazsky Inovec mountain has the main importance for origin, presence and chemical composition of thermal springs in Piestany. South-western slope of Povazsky Inovec is main infiltration zone for these springs. His crystalline core is composed from granite and gneiss in the center of the mountain. This bottom layer of the rocks is covered by secondary layers – dolomites, limestones and dolomitic limestones.
Rain water which is well penetrated through these rocks into deep (aprox. 2 kilometers/1,24 miles) is mineralized and heated by heat of the Earth. Hot mineralized water is springing on the surface by tectonic gaps between left side of Vah river and by-pass distributary, where most of the hot thermal springs rise. These are specially captured 50–60 meters (164-197 feets) under the ground to prevent mixture of thermal water with subsurface water. Total capacity of captured springs is over 3 million liters (aprox. 792600 gallons) of thermal water per day. They includes about 1500 mg of mineral substances per 1 liter (0.264 gallon) of the water, and gases - mainly sulphuretted hydrogen. The springs are sulphuric-hydrocarbonate, calcic-magnesian, sulphuric and hypotonic with dominant content of Ca, Mg, Na cations and SO4, HCO3, Cl and H2S anions.
Second natural healing source, that is mined from by-pass distributary of Vah river, where thermal springs arise, is thermal mud. This mud is one of the most healing peloid on the world. Peloids are natural substances, arose by * processes and activity of *, which are used for healing mainly rheumatic diseases. Peloids are small, rounded, spherical to ellipsoidal, cryptocrystalline carbonate aggregates commonly lacking internal structures. These aggregates generally vary in size from 30 to 100 µm and rarely exceed 500 µm. They exist mostly with thermal springs.
Your task is to:
1. Take a picture of hot thermal spring water and attach taken photo to the log. (There are at least 3 public places on Spa Island where you can do it.)
+ send answers to following questions, to my email address GeoKlipo(at)gmail.com:
2. What's the temperature of springing thermal springs from the depth of the Earth (tolerance ± 3°C).
3. Explain origin of the peloids.
4. Name at least 2 more spas in Slovakia where peloids are used for balneotherapeutical purposes.
