Rock-forming minerals of alkaline volcanic series associated with the Cheb-Domažlice Graben, West Bohemia.

Original language description

Two coexisting cogenetic volcanic series have been recognised in W Bohemia: weakly and strongly alkaline series. Early crystallization in the mafic rocks is manifested by olivine phenocrysts (Fo66-76), melilite, Ti-magnetite and (Ti, Fe+)-diopside to fassaite; in the intermediate rocks by diopside; and in the felsic rocks by (Mn, Ti)-magnetite, diopside, and high-temperature K-oligoclase (phenocryst cores). Continuing to late crystallisation in mafic to intermediate rocks in represented by kaersutite, nepheline (at T<700oC; also occurs with melilite in ijolite ongoing crystallisation is characterised by Mn-magnesioriebeckite, Mn-winchite and Mg-biotite; feldspars are prevalently anorthoclase (perthite), which occasionally mantles K-oligoclase and is succeeded by Na-sandine. Feldspars and quartz in the matrix of the felsic rocks terminate crystallization.
