Abstract: 

T. Dobrev, P. Stavrev, D. Yossiffov, R. Radichev, K. Vikov. Sputial distribution and morphological features of magmatic cryptobodies in Bulgaria according to geophysical data. Reported are results of studies related to the presence, positions, morphologies and sratial distribution of buried magmatic bodies in Bulgaria according to geophysical data gathered in scale 1:200 000. The methodology of interpretation is based on computer modelling of bodies and their anomalies. The analysis and descriptions are covering cryptobodies within upper 10–15 km of the earth crust southwards of Moesian platform. The highest density of magmatic bodies is related to the Srednogorie structural zone and mainly to its eastern subzone. All bodies are located within an interval of depths increasing from 7 km in the west towards 15-16 km in east direction. The number and relative percentage of basic bodies increase eastwards too. Predominating are layer-like bodies of fracture type. The results obtained are to be used for better understanding of the magmatism in the upper part of the earth crust and for an evaluation of low scale estimates of the ore-bearing potential of structural units in Bulgaria.
