Abstract

The Lausitz (Lusatia) Volcanic Field is part
of the Central European Volcanic Province, and its magmas
represent an alkaline trend from olivine nephelinites
and basanites to trachytes and phonolites, typical for
intraplate settings. Neighbouring volcanic fields are the
České Strˇedohorˇí Mountains to the south-west and the
Fore-Sudetic Basin in Lower Silesia to the east. More than
1000 volcanic structures associated with approximately
500 vents have been located within this volcanic field.
Residuals of scoria cones, lava lakes, lava flows and maardiatreme
in filling occur in situ near the level of the original
syn-volcanic terrain. In more deeply eroded structures,
volcanic relicts outcrop as plugs or feeders. Evolved rocks
occur as monogenetic domes or intrusions in diatremes,
while their volcaniclastic equivalents are rare. Twenty-three
localities were dated using the 40Ar/39Ar method. The ages
range from 35 to 27 Ma, with a focus around 32–29 Ma,
indicating Late Eocene and mainly Oligocene volcanism
for the LVF. Differentiated rocks appear to be slightly
younger than less differentiated. No geographical age clusters
are apparent.
