Azimov, 2010 Scientific Centre for Aerospace Research of the Earth, IGS, National Academy of Sciences of Ukraine, Kiev, Ukraine azimov@casre.kiev.ua 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- ��������� ��� ���������������������� 3 ��� ��!"#�$%&'�("�%()�#*+#�' #(&"�&��&,#��-�%()� �)#..'(/ 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 Fig. 1.

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 Fig. 2.

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 Fig. 3.

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. /#�)-(% '0%.�+,#(� #(%1 �� ��������� ��� ���������������������� Azimov O.
