Maximum high static levels of alkaline waters foreign to the
enclosing sections in the fields (Akhundov, Mekhtiyev and
Rachinsky, 1976; Rachinsky, 1989a, 1989b), etc.
A practical absence in this area of abnormally-high formation pressure
indicates, on one hand, the prevailing role of the geo-fluid-dynamic system
discharge in the formation of accumulations (Chapter 7), and on the other
hand, the substantially superposed effect onto this process of a number of
other geologic factors and mechanisms.
Similar correlations were found also in all other Alpine folded belt
regions (Figure 7.11). This gives legitimacy to the conclusion of predomi-
nantly vertical ground water flow in these regions and of migration control
mostly by the fault conductivity, by hydrogeological “windows”, elevated
fracturing, etc.
