Permo-Carboniferous subvolcanic rhyolitic dikes in the western Erzgebirge/Vogtland, Germany: a record of source heterogeneity of post-collisional felsic magmatism

Nearly contemporaneous evolution of the A- and S-type fractionated granites in the Krušné hory/Erzgebirge Mts., Central Europe

“…near Seifen and Hora Svaté Kateřiny (Breiter, 2008). Dykes of slightly peraluminous and P-poor rhyolites and microgranites were identified near Gottesberg, where they intrude the S-type granites of Eibenstock pluton (Förster et al, 2007;Wasternack et al, 1995). The characteristic features of these rocks are increased contents of zircon, monazite, thorite, xenotime, uraninite, pyrochlore and other minerals of REE and Nb-Ta Cocherie et al, 1991;Förster, 2006;Johan, 1994, 2005).…”

“…The peraluminous rhyolites are spatially associated with rhyolites of distinct A-type chemistry, but these two rock types do not intersect each other. Isotopic ages of both dyke types are superposed within the analytical errors (Förster et al, 2007) and therefore their age relationship could not be determined.…”

Superposition of burial and hydrothermal events: post‐Variscan thermal evolution of the Erzgebirge, Germany

“…Numerous studies deal with the Variscan evolution of the Erzgebirge (e.g. Kempe et al ., ; Förster et al ., ; Seifert, ; Linnemann and Romer, ; Romer et al ., ); however, its thermal history during Mesozoic and Cenozoic times is still insufficiently understood, as the post‐Variscan sedimentary record is incomplete or missing. Locally, the thermal history was influenced by ore‐generating hydrothermal fluids.…”

The Saxo-Danubian Granite Belt: magmatic response to post-collisional delamination of mantle lithosphere below the southwestern sector of the Bohemian Massif (Variscan orogen)

“…A minor late pulse of magmatism is also recorded in the South Bohemian Batholith, ~300 Ma (Freistadt granodiorite - Gerdes et al 2003). Some rhyolites in the Erzgebirge have the same Stephanian age (Förster et al 2006).…”
