AHFP in water horizons at elevations much exceeding the
exposure elevations of the corresponding intervals in the
Carpathians.

Regional waterhead decline toward the folded mountain
area (Kolody, 1983).
5.2.2.2
The Indolo-Kuban Trough
Various, sometimes diametrically opposite concepts were published regard-
ing the present-day ground water dynamics of the region. Gordievich,
Kortsenshtein, Sukharev, Kotov, Matvienko and Rogozhin considered
the present-day meteoric water infiltration in folded mountains of the
Mountainous Crimea and Caucasus Major to be a definitive influence on
the hydrodynamics of the Jurassic, Lower Cretaceous, Upper Cretaceous,
Paleocene-Lower Eocene and Neogene complexes. I.e., they assume the
existence and active functioning in the region of a typical artesian system.
Tverdilov, Yakovlev, Kartsev and Kolody believe that the Jurassic, Lower
Cretaceous, Upper Eocene (Kuma) and Oligocene-Lower - Miocene
(Maikopian) complexes over most of the trough area are under the eli-
sion regime with the infiltration charge involving only limited areas in the
piedmont and the adjacent territories. Formation temperatures in the basal
water complexes of the sediment section exceed 200°
С
. Kolody (1983) sug-
gests existence there of the thermohydrodynamic waterhead system caus-
ing piezo- and geothermal anomalies in the overlying elision systems.
These writers believe the leading role of the present-day infiltration in
the formation of hydrodynamic regime in the region's sedimentary section
to be unrealistic. It is refuted by:
t
The regional hydrodynamic barrier (Parpach-Akhtyr deep-
seated fault). It isolates the hypothetical meteoric charge
area in the mountains from most of the trough.
t
The step-block structure where the regional high-amplitude
lengthwise (Novotitarev-North Kerch, Anastasiyev and
Parpach-Akhtyr) and crosswise (Kurdjip, Tsitsin, Afip,
Gelendzhik, East Crimean, Dzhigin, Marfov, West-Kerch)
barrier faults (Figure 1.10) put water reservoirs in contact
with water barriers.
t
A lens-shaped nature of reservoirs on local highs and litho-
logical replacement over the basin's flanks of permeable clas-
tic varieties with impermeable ones (Yermolayev, Kotov and
Rogoshin, 1960; Kotov, 1963; Kucheruk and Ozerny, 1987).
