Abstract

In the southern part of the Little Hungarian Plain Neogene primitive mafic rocks occur in a relatively small area. Hydrovolcanic eruptions had great importance in the evolution of volcanic edifices owing to the interaction of water and hot magma. Magmatic explosive events and lava flows appear to be related to late phases of the volcanic activities. Geochemistry of the mafic rocks of individual volcanoes is almost homogeneous. However, there are significant chemical variations among the different volcanoes suggesting small scale mantle heterogeneities. Petrogenetic model calculations indicate that the primary liquids could have generated by 0.5 to 1.5% batch partial melting of moderately enriched (E-MORB-type) mantle sources. Garnet and K-bearing phase could have remained in the residue. -from Authors
