Description	On the basis of a new volcanological model and geochemical investigation in the České středohoří Mts., the following volcanostratigraphic formations were recognized: (i) the Lower Fm. - lavas and volcaniclastics of basanitic character (36-26 Ma; Mg# = 57-76; 87Sr/86Sr = 0.703128 -0.703526 and 143Nd/144Nd = 0.512738-0.512849) corresponding to primitive upper mantle products; (ii) the Upper Fm. - lavas and volcaniclastics of trachybasaltic type (31-25 Ma; Mg# = 41-58 87Sr/86Sr = 0.704428-0.704649 and 143Nd /144Nd = 0.512679-0.512742) representing differentiated and partly crustal-contaminated evolved products; (iii) the Uppermost Fm. - flow(s) of basanite (24 Ma), similar in geochemical characteristics to those of the Lower Fm. Volcaniclastic products of the Lower Fm. (Mg# = 51-69) and the Upper Fm. (Mg# = 45-51) also substantially differ in bulk composition. The volcaniclastics underwent alteration to a different degree, which has significantly changed their geochemical signatures.
