Three main volcanic periods can be distinguished based on K-Ar data and known paleostress fields: (i) pre-rift (79–49 Ma), (ii) syn-rift (42–16 Ma) and (iii) late-rift (16–0.3 Ma), with the youngest period further subdivided into three episodes. The dominant mafic rock types of all periods are of nephelinite – basanite / tephrite composition. The exceptions are suites of ultramafic rocks of the pre-rift period and of the final episode of the late-rift period. The most voluminous are volcanic rocks of the syn-rift period occurring in the Ohře Rift Graben. The initial Sr-Nd ratios of the mafic volcanic rocks of the Bohemian Massif are characteristic of magmas derived from a sub-lithospheric mantle source. The isotopic ratios resemble those of the HIMU mantle source. Workplace Institute of Geology Contact Jana Popelková, popelkova@gli.cas.cz, Sabina Janíčková, Tel.: 233 087 272 Year of Publishing 2012
