Figure 2.10. South Caspian Depression. Bibieybat Field. Chlorine-calcium and alkaline
water distribution in different horizons: a. Structure at the top of KS Formation;
b.  Structure at the top of XII interval; c. Mud volcano; alkaline water distribution: d.
For the formation of XI—XII interval; e. For the formation of XII interval; f. For the
formation of XIII interval; g. For the formation of XIV interval; h. For the formation of
XV interval; and for the KS Formation; i. wells.
Thus, the hydrochemical, lithological and physicochemical geologic
environments are similar on both flanks of the depression despite a quite
different temperature background. It gives reason to believe that the dif-
ference in the depths of the permanent sulphate presence in waters of the
eastern and western flanks, and correspondingly in the conditions of their
preservation from the microbial sulphate reduction, is determined mostly
by a single factor— a greater heating of the east flank subsurface. It causes
a lower intensity there of the microbial sulphate reduction at much shal-
lower depths compared with the western flank (Rachinsky, Aliyev, 1973).
