APPLICATION OF STABLE ISOTOPES (~(18)O, D) TO STUDY THE PROVENIENCE OF MINERAL WATERS FROM SOME LOCATIONS OF ROMANIA

摘要

The isotopic study (~(18)O, D) of mineral waters from some locations (Bucovina, Covasna, Tusnad and Someseni) of Romania was realised in tentative to identify him origin. The investigations of waters from Bucovina, Covasna and Someseni (Springs No. 1,2, and 15) confirms the meteoric provenience, having the deuterium content of meteoric water, but shifted to higher ~(18)O content. This ~(18)O shift is the result of isotpic exchange of the water oxigen with the rocks oxigen in his trajectoty to the descharge. The Spring No. 8 waters from Someseni Spa and Tusnad waters present the water isotopic content of mixed deep water with shalower meteoric water having hivier isotopic (D, ~(18)O) content. The Spring No. 3 waters from Someseni Spa present the springtime isotopic puls, like a Becas brook, with water depletion in D and ~(18)O isotopes proving polution with surrounding snow water.
