1. One of many problems in dynamics of litho-
sphere is the origin and development of rift sys-
tems inside and on the skirts of ancient platforms,
in particular, the Pripyat-Dnieper-Donetsk avlaco-
gen in body of East-European platform. The ver-
sion about an origin of this avlacogen as a result
of "superregional" right-hand shift lengthways
Sarmat-Turan lineament, or more global (trans-
continental) prolongation of this lineament to the
west and to the east corresponding to the Schet-
land-Tsinlin fault-displacement [Roslyi, 2006; Is-
berg, Starchik, 2007], is well known. Horizontal
Model for formation of Pripyat-Dnieper-Donetsk system of formation of paleorifts: a — location of board`s zones of paleorifts
and structures of iron-ore formations in earlyproterozoics time (1000 m. years ago); b — present location (1 — magnetic
anomalies in earlyproterozoics time (Krivorog`s and Kursk series [Zankevich, 2006]; 2 — boundaries of proterozois geosyn-
clines zone; 3 — proterozois fault in massif of the Sarmat`s shield; 4 — boundaries fault of paleorifts; 5 — the trajectory of
movement of conventional point A–A1; O–O1 — dislocation of rotation axis of the Ukrainian shield).

displacement of shift within the limits of described
region makes 250—400 km.
Our reconstruction confirms displacement on
400 km and assumes turn of the Ukrainian shield
clockwise on 38° with respect to southern suburb
of the East-European platform in area of the Voro-
nezh massif. The radius of turn is 650 km, and the
center of rotation is gradually displaced to the "north"
on 150 km. As a result initial points O and A (see
Figure) have � �=��$�=���������>1

1.
The above reconstruction is based on the as-
sumption of genetic connection of the magnetic
anomalies of the Krivoy Rog — Krementchug and
Kursk iron-ore formations as uniform linear struc-
ture in early proterozoic time. Slanting break (under
an angle 60° to an axis) of this structure has begun
right-hand shift, formation and expansion of rift cleft.
2. The process of transregional shift started at
the beginning of late proterozoic era (1 bln years
ago), proceeded non-uniformly, being entered du-
ring general planets tectogenes epochs, it was
marked by formation of “rifey graben” in a south-
east part of the future Dnieper-Donetsk paleorift, it
brightly showed itself by formation of described rift
system in late devonian epoch and has practically
come to naught in cretaceous-paleogen times.
However and nowdays in a landscape and a geo-
logical structure of region it is possible to observe
neotectonic attributes of the latent movement: ring
and linear aircosmic anomalies are displays of tan-
gential and normal deformations in a sedimentary
cover, listric faults [Geology ...,1991]. Shift right-
hand deformations are clear visible along borders of
rift forming deep breaks, lengthways the Smelov-
Kholm diagonal break, in places of breaks of the
Sarmat-Turan lineament, they are well traced along
chains of salt rods in the central and south-east
parts of Dnieper-Donetsk paleorift [Geology ...,1991;
Kurilenko, Janshina,1988; Roslyi, 2006].
3. Rift formation combined with stretching, ex-
tension and crushing of basement blocks, it was
accompanied by faulting of every possible types,
listric chipping off, overturning and dropping of se-
parate blocks, extensive landslides. Deformations
of a stretching were non-uniform along described
system of paleorifts: for the Dnieper-Donetsk gra-
ben it was 2—5 km in its extreme north-west, 5—
7 km in a middle part and 10—18 km in a southe-
ast. The Pripyat graben was generated mainly un-
der influence of shift deformations, and broadening
here did not exceed 2,4 km.
The paleorifts width also is changeable along all
the system spreading. The Pripyat graben extends
in the western direction from 110 up to 160 km at
thickness of a sedimentary cover from 2,5—4 km
above ledges of the base up to 5,5—6,0 km above
the immersed blocks. The Dnieper-Donetsk graben
extends in a southeast direction from 75—90 km up
to 110—130 km, being correlated with increase of a
sedimentary cover in board zones from 3—4 km in
the west up to 6—7 km in the east, and along an axial
zone — from 6 up to 18 km in the same direction.
4. The bottoms of paleorifts (“rift valleys”) are
formed by “the breccia of rubbing” arisen under in-
fluence of transcontinental shift and consisting main-
ly from different sizes products of grinding blocks of
crystalline rocks from basement and vulcanites. The
range of the sizes of these "products" is very wide:
from blocks in volume in hundreds cubic kilometers
up to boulders and pebbles. A filler of these breccia
are products of erosion and drift from onboard sites
(mainly clastits), endogenous materials (effusive and
halogens), chemic- and biogenic materials (carbo-
nates). The same initially not consolidated depo-
sits provided noncompensated filling of paleorifts.
Proceeding from the above stated representa-
tions, and taking into account an idea about of struc-
ture (fractality) and “geoblock divisibility” of the
earth's crust [Krasnyi, 2005; Zankevich, 2006], the
structure of paleorifts (their board`s and bottom) can
be represented as system of relatively stable weak-
ly deformed ("rigid") blocks divided by labile (unsta-
ble) zones of “hummocking”. Stable blocks under
influence of transregional shift deformations exer-
cise some progress-rotary movement, and labile
zones compensate superfluous pressure, playing a
buffer role between blocks. Indicators of labile zones
are anticlinal folds and chains of positive structures
in a sedimentary cover. The majority of structures
have attributes of imposed folding (dragging, sque-
ezing, etc), complicated by halokinesis. Within the
limits of labile zones the salt domes, often built in
rhythmical chains or ring formations are located all.
The overwhelming majority of oil and gas fields con-
taining the lion's share of oil-gas provinces is rela-
ted to labile zones.
Thus, the new approach is outlined in the tec-
tonic zoning of the Pripyat-Dnieper-Donetsk oil-gas
province and allocation on this basis of perspective
zones of oil-gas accumulation that should raise a
level of a scientific substantiation of accommoda-
tion of volumes of exploration.
