.reation of 3D regional magnetic model of the East European Craton (EEC) for spherical Earth’s
needs corresponding cartographic support notably availability of a geomagnetic maps of a geomagne-
tic anomaly of the total intensity scalar ( /)

and its normal component /IGRF. At present time there are
published and digital maps of a geomagnetic field, that give a possibility to perform a small-scale
zoning, to separate a regional component ( /)
0.reg.,as well as to evaluate inhomogeneity degree of the
Earth’s magnetic field. The first map of anomaly magnetic field for studied territory has been deve-
loped under the editorship of Z. A. Makarova [The Map …, 1977]. Next important achievement in mag-
netic mapping was creation a map of anomaly mag-netic field of the Europe under the editorship of T.

UNESCO became the results of common 50-years
researches concerning analyses of different-time and
non-uniformly scaled terrestrial, marine, aero- and
3D magnetic model of the East European Craton (a) and magnetic anomalies from a model on height 400 km (b) and 200 km (c):
1 — boundary of the EEC, 2 — contours of lower, 3 — upper magnetic sources (in case of the inclined lateral sides).
satellite surveys. These maps enabled to separate
a regional component of the EEC magnetic field and
to propose as a first approximation a 3D magnetic
model of the Earth’s crust [Orliuk, 1984; 1996; 2000;
Orliuk, Pashkevich, 1995; Pashkevich et al., 1990].
Digital map of the regional component of EEC ano-
maly magnetic field was developed [Orliuk et al.,
2007] with using the results of the works [Orliuk,
2000; Purucker, 2007]. Developing 3D Earth’s crust
magnetic model of a big territories it is important to
take into account the values of Earth’s normal mag-
netic field �IGRF. For the EEC on the epoch of 2005
[http://ccmc.gsfc.nasa…] minimal values of the field
�IGRFare observed in south-western part of the terri-
tory (48000 nT) and maximum values — in the north
and north-eastern of the territory (56000 nT).
First approximation of regional magnetic model
for EEC was formed with using digital anomaly
magnetic maps, Precambrian basement depths,
temperature within the crust and petromagnetic rock.
3D regional magnetic model of the territory (Figure)
was developed in the sequel using program-algo-
rithmic complex [Kovalenko-Zavoisky, Ivashchenko,
2006] to solve direct task of magnetometry in spheri-
cal coordinates. The models of magnetic sources
were set a few spherical blocks, each of which was
characterized homogeneous magnetic susceptibi-
lity, and different, in the case of necessity, values
component of the normal geomagnetic field.
Depth of magnetic sources was set in limits from
10 km (depth of a top edge of magnetic sources) to
40 km (depth of a base surface). The field calculated
by model was compared in terms of quantity with the
interpreted field. After several iterations the minimal
differences between these fields were achieved.
Under obtained model of the EEC there are a large
Earth’s sections with magnetization values from 0,5
to 1,75 A/m and which sizes are 200—300 km. The
sources having magnetization values 1,0—2,0 A/m and
sizes of 40—100 km are located in the limits of these
blocks. The magnetization values more that 2 A/m
are inherent to the solids that are the sources of
such regional magnetic anomalies as one: Kursk
(>6,35 A/m), Odessa (3,5 A/m), Lvov (3,18 A/m),
Gaisyn (3,23 A/m), West-Ingulets (3,6 A/m), Kiev
(2,71 A/m), Kungursk (3.72 A/m) et al.
Intensity of magnetic field from 3D magnetic mo-
del at height of 10 km changes in limits �
�
= (300—
1200) nT, on height of 200 km �
�
= (15—70) nT
and at height of 400 km �

= (4—14) nT.
As you can see from figure sources of magnetic
anomalies are situated to boarder part of the EEC.
