Abstract: Plutonic
rocks intrude the metamorphic basement rocks of the Rhodope massif. Aeromagnetic
data from a 1966 survey of Macedonia and Thrace were recompiled, processed
and used in the present study to interpret the anomalies associated with
the Leptokarya granite. The data were inverted by means of a terracing technique
that defines separate domains of uniform distribution of physical properties
causing magnetic anomalies.
The anomalies were separated in the wavenumber domain. The sources of the
short-wavelength anomalies were interpreted as granitic domes. The aeromagnetic
data were differentially upward continued to the constant altitude of 3275
m. The magnetic field produced from this procedure was used to interpret
the long-wavelength part of the Leptokarya anomalies.
