Hidrojeologic Investigation ofYeşityurt-Çelikhan (Malatya-Adtyaman) Surounding, SW Anatolia, Turkey
ABSTRACT: Stratigraphie squence of th.e area consist of the Pötürge Metamoxphic in Pie.rmo~!Ca:rbonifer, Maden. Complex In Eocene,, Malatya Metamoiphics im Pe-imo-Carponifer,, Göndûzbey group in C:retaceou.ss Yeşilyuıt group,. Gedik formations in. Eocene, Kilayik and Beyİerderesi formations in Miocene, The occurrence of the springs in the study area are effected by karsttification, karst-fault, boundaûrs of the permable and impeimable rock units an,d faults. Pınarbaşı spring 300 1/s, Horata ` sprâg 9Ö1 1/s and tnekpuian spring 0-30 l/s are. The small springs are changed between 0,52-0,2 1/s. The general chemical classifications of `these springs are as the following: amons rHCQ`j > rQ" > 1SQ4"" and. cations r{Ca+i+` + Mg+ + ) > rNa+ > rK+. According to Piper `these waters are "Alcalie earth. (Ca++ + Mg+ + ) > exveed alcaie elements (Na+ + K+) and "carbsonate hardnees excedds than ^SQ1"; according, to in Schoeller classification are"1` normal chlorine» sulphate (and. carbonate, waters*1; according to Şahinci -these waters are also A-Iab(ba), A j C-Iab(baX AC-Hab(ba) and C2A.-Ha.DCab).. According, to Sar classification the pong waters are `"excellent for irrigation",,, C2-S1 according to1 USA... laboratory salinity diagram is; although in Wilcox diagram arc "excellent to
