The optimum, effective and economic advantageous complex of geochemical criteria of determination of the second salt halos of heavy metals of natural and tehnogenic origin is developed. The set criteria will be allowed at first in the decision of direct searches of minerals after the second halos of dispersion, and secondly in the decision of tasks of ecological character. For this purpose different methods of research were used - chemical, ion-selektiv, atomic-absorption, thermodynamics analysis, method of mathematical design. On the separate areas of territory of Ukraine (Pergansky, Yasinetsky, Zakarpatsky, Pridnestrovsky, Pobugsky, Polohovsky, Shidnolipovenkovsky, Stanichnolugansky, Kamennomogilsky and Artsizky) the study of the second halos is conducted. Criteria are got on by which possibly to set nature of their origin - on the relation of degree of mobility of element-indicator in the overhead and lower ground horizon, on the relation of complex of gydrocarbonate and sulfate forms, on the morphological features of salt to the halos and others. .
