Abstract
Originally the lower cretaceous volcanics known from boreholes of the Great Hungarian Plain proved to be feldspar-rich basaltic rocks. They are highly altered volcanics (Mg-metasomatism, spilitisation, weathering), and they contain as fresh component parts some grains of clinopyroxene. From electronmicroprobe analysis-data of the minerals is shown, that the pyroxenes are of diopside-salit-augite composition. It can be stated, that the analised grains refer to alcali magma, therefore the high alcalic content in the rocks is a result not only of metasomatism and contamination. The pyroxene analitical data supported the conccption of rock-origin, that they are products of continental within-plate volcanism.
