Mineralogy and petrogenesis of a Ba-Ti-Zr-rich peralkaline dyke from Šebkovice (Czech Republic): Recognition of the most lamproitic Variscan intrusion

Original language description

A peralkaline, ultrapotassic dyke found at Šebkovice is a mineralogically extreme member of a dyke swarm occurring along the SE border of the Moldanubian Region of the Bohemian Massif. The dyke shows a simple zoning with a very fine-grained marginal zonegrading into a medium-grained central zone. It has a primary mineral assemblage of microcline and potassic amphiboles with accessory apatite and altered phlogopite. The core of the dyke and late veinlets contain unique late- to post-magmatic Ba-Ti-Zr-bearing mineral assemblages of baotite, henrymeyerite, titanite, rutile, benitoite and bazirite. In terms of a mineralogical-genetic classification, the Šebkovice dyke can be considered as a new high-silica variety of lamproite and represents a unique expression of post-collisional potassic magmatism on the south-eastern border of the Bohemian Massif. In terms of the modern classification of lamproites, the Šebkovice dyke is the first lamproite recognised in the Variscan orogenic belt.
