Quantitative interpretation of magnetic anomalies,the sources of which lie in the Inner Carpathian subjacent rocks in eastern Slovakia, have made it possible to determine probable locations of these sources in a geological section. Derived aeromagnetic maps have provided information on areal distribution of these specific rocks partly underlying near-surface neovolcanic complexes. Petrophysical studies of rock drillcore samples have shown that the magnetic anomalies are caused by variously serpentinized (lizardite, chrysotile) peridotites resembling highly serpentinized spinel peridotites present in a number of tectonically confined bodies of the Meliata Group. The above-mentioned common characteristics make us assume mutual genetic relationships between these rocks, and their common spatial as well as temp oral origin during the formation of the "Meliata-Vardar" oceanic crust.
