Abstract - Summary 
(short description):
Mineral composition, structure and formation conditions of the XII ore zone of the Yermakovka F-Be deposit were studied. The XII zone is enriched by fluorite but contains less than 0.1% BeO. The main body of the XII zone was formed by cavities filling, rather then by ore-bearing alteration of low-calcium aluminosilicate rocks. Ore-forming solutions of the XII zone are similar to those of Be rich apocarbonate, in Be concentrations (up to 5.2 and up to 6.1 g/kg, respectively). However, the formers solutions have increased acidity (pH≈4 in 350—). According to the calculated data, cooling of these solutions up to 100— wasnít accompanied by the reduction of Be-F-complex solubility, which results in the low Be content in the ore body.
