Features of hydrogeochemistry of natural waters the tracts of the Kastropol (southern coast of the Crimean peninsula)

Abstract

This paper presents comprehensive hydrogeochemical studies of the natural waters the tracts of the Kastropol. The studied waters are mainly characterized by HCO Ca and HCO Mg-Ca composition with total mineralization, which varies from 220 to 2306 mg/dm and silicon content from 0,78 to 6,08. The geochemical parameters of the environment vary from the reductive to oxidative setting with Eh from -146,6 to +275,9 mV; pH from 7,4 to 8,5, and O from 1,80 to 7,73 mg/dm. Natural waters were divided into two geochemical groups by geochemical coefficients that differ from each other in their relations Ca/Na, Ca/Mg and Si/Na. B, Br, I, Re и Au accumulate in the waters. Li, B, Sr, Re and Au have a very strong migration ability in solution. According to the indices of water pollution with heavy metals, a high degree of enrichment of the waters of wells in the Partizanskoye village was established.
