Cenozoic alkaline volcanic rocks with carbonatite affinity in the Bohemian Massif: Their sources and magma generation

Original language description

Melilitic alkaline rock suite of the Osečná Complex and mildly alkaline rock suite of the Roztoky Intrusive Complex, both with carbonatite affinity, were studied to determine the source of magma for alkaline volcanism in the Cenozoic Central European Volcanic Province. No significant correlation exists between element contents in the extremely SiO2-undersaturated melilitic rock suite of the Osečná Complex. Geochemical variations can be explained by metasomatic overprinting. The rocks represent a productof primitive mantle-derived magma. The rocks of the essexite ? monzodiorite ? sodalite syenite series and associated differentiated dykes of the Roztoky Intrusive Complex are characteristic by mild SiO2 contents, are depleted in compatible elements andtheir magma represents an evolved melt. Correlations between the elements point to fractional crystallization of olivine, clinopyroxene, Fe-Ti oxides and apatite. The rocks geochemically correspond to the trachybasaltic lavas of the České
