摘要: The upper Miocene of Karlovassi Basin, Samos Island, Greece, contain continental evaporites such as colemanite, ulexite, celestite, gypsum and thenardite. These are related with volcanic tuffs, diagenetically altered in a saline-alkaline lake environment. aim the present paper is to: a) define impact already known possible buried borates other to geochemistry hydrogeological system and; b) assess correlation between surface underground evaporite deposits considering spatial changes concentrations examined physicochemical parameters. Fieldwork, laboratory measurements literature data revealed elevated boron values (2136–33012 ⧎/L) central part Basin. In same area, high amounts strontium, sodium, lithium sulfates also occur. It proposed that these ions originate from leaching authigenic minerals Sr-rich clinoptilolite boron-bearing potassium feldspar. Boron abnormally for freshwater aquifers, indicative presence basin unknown significance.
