Název v původním jazyce

Plio-Pleistocene basanitic and melilititic series of the Bohemian Massif: K-Ar ages, major/trace element and Sr-Nd isotopic data

Popis výsledku v původním jazyce

The Plio-Pleistocene volcanic rocks of the Bohemian Massif comprise a compositional spectrum involving two series: an older basanitic series (6.0-0.8 Ma) and a younger, melilititic series (1.0-0.26 Ma). The former consists of relatively undifferentiatedbasaltic rocks, slightly silica-undersaturated, with Mg# ranging from 62 to almost primitive mantle-type values of 74. The major and trace element characteristics correspond to those of primitive intra-plate alkaline volcanic rocks from a common sub-lithospheric mantle source (European Asthenospheric Reservoir - EAR) including positive Nb, and negative K and Pb anomalies. 87Sr/86Sr ratios of 0.7032-0.7034 and 143Nd/144Nd of 0.51285-0.51288 indicate a moderately depleted mantle source as for other maficrocks of the central European volcanic province with signs of HIMU-like characteristics commonly attributed to recycling of subducted oceanic crust in the upper mantle during the Variscan orogeny. The melilititic series is characterized b
