It is identified that by their formation mechanisms
the known and forecasted fracture dislocations at a
recent stage of their geotectonic development ma-
nifest themselves mainly as the zones of stretch-
ing. The disjunctive structures of this type are al-
ways well decoded on different-scale remote sens-
ing data (RSD) of any region of study. Their geoindi-
cators are characteristic of zones of increased flu-
id-geological permeability.
Let’s consider a territory of the Chernobyl Ex-
clusion Zone and an adjacent region of the Koros-
ten pluton. For its landscape-geological conditions
the geoindication constituents of fractures are rep-
resented usually by the negative relief forms, su-
per-humid sites with developed species of hygro-
philous vegetation, elongated lines of anomalous
phototone change to darker hues, etc. At once for
mentioned region as an example (specifically for
the Tovstyi Lis site within its borders) we classified
the basic landscape geoindicators of the discrimi-
nating geodynamic fields at the recent tectogene-
sis stage. The fields are related to the Earth’s crust
disjunctive structures. Peculiarities of the fields’
reflection in the RSD are characterised too [Azi-
mov, 2008; 2009].
During investigation first of all it was taking as a
base the framework of a tectonic structure of the
studied area (Fig. 1, 2) chosen in the course of the
regional research stage [Azimov, 2001; 2002; 2003].
It was worked out in detail within the Tovstyi Lis site
and its adjacent areas [Azimov, 2004; 2006; Geo-
logical …, 2006]. For example, determination of the
rectilinear known and forecasted structural elements
of disjunction character (or structural lines, linea-
ments) on the remote images of high space resolu-
tion and topographic materials was performed with
using a set of criteria (geoindicators): boundaries of
sites with a different degree of the relief dissection
and dynamics of erosion processes; rectified boun-
dary segments of hypsometric benches, gradient
steps of the relief, river valleys, banks of small lakes
and swamps, erosion network, troughs, grooves,
gullies, water divides, bent water courses and val-
leys, linearly elongated chains of suffusion depres-
sions, mikrodepressions, erosion-denudation bo-
dies, sandy ranges, as well as boundaries of the
Quaternary deposit complexes and their lithofacies,
sections with specific facies of hygrophilous vege-
tation, elongated lines of anomalous variations of
image phototone, etc.
A location scheme for the lineament structures
obtained by decoding show high lineaments densi-
ty, for this reason direct identification of the fracture
dislocations is difficult. For finding regularities of the
lineaments distribution, their typification was done
according to their manifestation indicators at remote
images or the site, their relation with geological
objects and inter-correlation between each other,
elongation, width, etc. Usually zones of decoded
lineaments appear to be wider than zones of frac-
tures revealed by geological-geophysical methods.
The latter ones are located in the middle of linea-

ment zones. This gave possibility to refine the are-
as of anomalous geodynamic influence of fractures
activated at the recent stage of the Earth’s crust
evolution.
In the course of direct study of the general struc-
ture of an elementary lineament field within studied
the Tovstyi Lis site it was found that differently ori-
ented separate elementary structural lines are
grouped in lineaments and their zones, saturating
and depicting their internal construction. They are
grouped into regularly built systems of definite di-
rections, mainly diagonal with prevailing azimuths
from 40 to 50 (north-eastern), and 310 (north-west-
ern), and orthogonal ones directed with azimuth 0 5
(submeridional), and 270 5 (sublatitudinal). These
systems control each other by stretch and size.
Practically each of them finds its orthogonal sys-
tem, forming with it a dynamic pair, and one sys-
tem from this pair prevails in its development. With-
in boundaries of the definite site the structural lines
of definite direction dominate (Fig. 3). Linear ele-
ments correspond well by their directions to the main
fracture systems of Ukraine revealed by different
methods [Chebanenko, 1977]. The latter ones dur-
ing the platform stage had been developing in corre-
lation, forming the entire dynamic system of co-sub-
ordinated stably coupled fractures of diagonal and
orthogonal orientations.
The above data enable to conclude that the ma-
jority of lineaments and their zones decoded from

the RSD come along the axes of discharge of stress-
deformed rock state, that indicate a presence of
the local disjunctive fractures or components of break
structures of various lower-rank morphogenetic types
developed in the Earth’s crust within studied area.
They represent the boundaries of main block fields
within which the localization of anomalous geody-
namic stresses takes place.
In the course of interpreting the neo- and recent
geodynamical situation the known facts were taken
into account [Chebanenko, 1977; Pavlinov, 1977;
Geodynamic …, 1989] stating that during the ten-
sile deformations the fractures are formed followed
by faults, separations, rifts, combined shift-faults,
and during the compressing stress deformations —
by uplifts, joints, thrusts and coverings with com-
bined forms of shift-uplifts and shift-thrusts.
Linear contraction zones within the Tovstyi Lis
site are of significantly scarcer occurrence, or their
distinguishing by aerospace decoding materials is
difficult (see Fig. 3). This is obvious. Structures of
this type are indicated mainly by additional relief
forms, such as: rectified sections of water divides,
erosion-denudation bodies, sandy ranges, etc.,
which are often distinguished in the aerosurvey data
by the anomalous (lighter) image phototone. Some-
times fractures change their characteristic along
their stretching direction from strain to contraction
zones, that is evident from the interaction of stres-
ses and location of axes of regional and local stres-
ses in each particular tectonic block formed by the
disjunction system.
According to morphological assessments, the
majority of fracture deformations studied in more
detail are represented in plane by typical shift faults
(proper shifts and transformed fractures) related with
horizontal movements of rock masses. This follows
from the analysis of an internal structure of zones
represented by bands of shingling longitudinal se-
parate chips, and their spatial relation. The latter is
most prominently seen in the regions of intersec-
tion nodes of these dislocations.
At the Tovstyi Lis site right shears prevail (ex-
cept for zones 4—4, 5—5, 7—7, the south-eastern
part of zone 6—6 and the submeridional zone without
number located to south-east from Tovstyi Lis vil-
lage). Some elongated shear dislocations in their
stretch direction change their movement sign to the

recognized); 5 — contour of the Tovstyi Lis site of detailed investigation.

opposite (from left to right and vice versa). This is
caused also by changing the active direction of shear
stresses.
Hence, based on the tectonic-physical interpre-
tation of available aerospace image decoding ma-
terials and geological-geophysical survey data, within
the studied area the regularities of a systematic hie-
rarchy of the fault-blocked structures are revealed.
More detailed analysis of the distribution of differ-
ent-directed deformations at the studied site enable
to separate the local areas of predominant develop-
ment of the strain and compression stresses which
concentrate around the nodes of intersection of
paragenetically related diagonal and orthogonal frac-
tures (see Fig. 3).
Characteristic landscape elements of the local
blocks areas subjected to compression forces are

the positive relief forms (mainly water divides), in-
creasing of the part of sandy litho-facies, etc. Cha-
racteristic for the areas of dominating development
of the strain deformations are the negative relief forms
manifesting in swamped areas, small lakes, reser-
voirs, homogeneously distributed microdepressions,
suffusion forms, etc., determined by runoff-less cha-
racter of surface waters. On the aerospace images
they can be identified by presence of characteristic
soil-geobotanic features manifesting themselves
mainly by anomalous (darker) image phototone, as
compared to neighboring areas.
Thus, considered aspects of RSD using are evi-
dence of the high geologic unformativity of aerospace
survey materials. Methodological techniques of RSD
using can be employed efficiently for solving a whole
number of the interiorusing problems.
