Геатэрмiчныя ўмовы і геахімія гарачых крынiц гары Сабалан (паўночна-заходнi Iран)

Мясцовасць гары Сабалан выбрана ў якасцi найлепшага аб’екту для вывучэння геатэрмальнай актыўнасцi ў паўночна-заходнiм Iране. Пачынаючы з апошняга эпiзоду вулканiчнай дзейнасцi ў плiа-чацвярцічны час, праявы гарачых крынiц вады i пару на зямной паверхнi сведчаць аб геатэрмальнай актыўнасцi ўздоўж схiлаў гары Сабалан. Гарачыя флюiды, якiя цыркулiруюць у гэтым геатэрмальным полi, утрымлiваюць галоўным чынам анiёны HCO₃^– i Cl^–; аднак ўтрыманне SO₄^2– у асобных пробах вады параўнальна высокае, што сведчыць аб сульфатных якасцях гэтых флюiдаў. Даследаваннi з выкарстаннем геатэрмометраў адзначаюць, што тэмпература ў калектары ацэньваецца прыкладна ў 150 °С на вывучаемай плошчы. Ў гэтай сувязi геатэрмальная сiстэма ўсходняй часткi гары была вызначана як высокатэрмальная. Гарачыя крынiцы на плошчы Сарэйн (Sarein) утрымлiваюць максiмальную колькасць Na⁺. Найвялiкшае ўтрыманне Ca²⁺ адзначана на плошчах Сардабех (Sardabeh) i Еддзiболуг (Yeddiboloug). Максимальнае ўтрыманне для K i Mg – 40 i 20 мг/дм³ адпаведна. Дадзеныя па канцэнтрацыi крэмнязёму ў водным растворы могуць быць выкарыстаны ў якасцi геатэрмометра. Трэшчынаватасць стварае другасную прапушчальнасць i садзейнiчае выхаду высокатэмпературных геатэрмальных флюiдаў.
