Coexisting Miocene Alkaline Volcanic Series Associated with the Cheb-Domažlice Graben (W Bohemia): Geochemical Characteristics.

Original language description

The Middle to Late Miocene alkaline volcanism of W Bohemia is associated with the uplift of the NE flank of the Cheb-Domažlice Graben. Two coexisting volcanic series have been recognised there: (i) weakly alkaline series and (ii) strongly alkaline series. Modelling of the partial melting showed that nephelinite and basanite magma formed by different degree of partial melting of the magma source with the amphibole, garnet, olivine and clinopyroxene in the residuum. The mantle source was probably represented by lithospheric mantle metasomatised by the plume-like material. Evolution of the stongly alkaline series is limited in extent and rather unclear. The weakly alkaline series is well developed and its evolution can be modeled by fractionation of olivine, clinopyroxene, Fe-Ti oxide and small proportion of plagioclase and in late stages by alkali feldspar, Fe-Ti oxide, clinopyroxene and apatite.
