The M{\"u}nchberg nappe pile consists of at least five large tectonic units which exhibit differences in lithology, in part also in metamorphie grade and in metamorphie history. The metabasites in each of these nappes show their own, significant geochemical characteristics. The lowermost tectonic unit, the Bavarian lithofacies, includes the anchimetamorphie Ordovician Randschieferserie which contains alkaline basalts. In their geochemistry, they are sirnilar to the metabasites of the Fichtelgebirge crystalline complex in the autochthonous Saxo-thuringian. The next higher tectonic unit of the M{\"u}nchberg nappe pile, the Prasinit-Phyllit-Serie contains metabasites which can be derived from subalkaline basalts with a clear calc-alkaline tendency. There is a striking geochemical resemblance to the metabasites of the Erbendorf Greenschist Zone (EGZ) underscorinq the similar lithology of both allochthonous units which appear to be in a similar tectonic position. The Randamphibolit-Serie higher up in the M{\"u}nchberg nappe pile consists of metabasites with tholeiitic characteristics and a pronounced differentiation trend. The next higher tectonic unit, the Liegendserie of the M{\"u}nchberg gneiss cornplex s. str., contains metagabbros to metagabbronorites with a high-Al basaltic composition. The amphibolites and banded hornblende gneisses of the overlying Hangendserie are of subalkaline basaltic character with calc-alkaline affinity. The Zone Erbendorf-Vohenstrauss (ZEV) is currently regarded as an allochthonous unit equivalent to the higher crystalline nappes of the M{\"u}nchberg pile. However, the geochemical character of the metabasites do not encourage such a correlation. Neither the schistose and striped amphibolites nor the flaseramphibolites of the ZEV with their N-KORB and E-MORB character respectively, find convincing counterparts in the crystalline nappes of the M{\"u}nchberg pile. However, an interestingly close resemblance exists between the schistose and striped amphibolites in the ZEV, on the one hand, and in the autochthonous Zone Tirschenreuth- M{\"a}hring (ZTM) and the adjacent Moldanubian sensu strictu, on the other. Owing to the absence of age criteria, our results cannot be used, so far, to reconstruct the paleogeographical position of the individual tectonic units, based on the geochemical characteristics of their respective metabasites.}, language = {en} } @inproceedings{SchuesslerOppermannSeideletal.1986, author = {Sch{\"u}ssler, Ulrich and Oppermann, U. and Seidel, E. and Okrusch, M. and Richter, P.}, title = {Vergleichende Untersuchungen an Metabasiten des ostbayerischen Kristallins}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-39212}, year = {1986}, abstract = {No abstract available}, subject = {Kontinentales Tiefbohrprogramm}, language = {de} } @article{SchuesslerOppermannKreuzeretal.1986, author = {Sch{\"u}ssler, Ulrich and Oppermann, Uwe and Kreuzer, Hans and Seidel, Eberhard and Okrusch, Martin and Lenz, Karl-Ludwig and Raschka, Helmut}, title = {Zur Altersstellung des ostbayerischen Kristallins - Ergebnisse neuer K-Ar Datierungen}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-31778}, year = {1986}, abstract = {No abstract available}, language = {de} } @article{SchuesslerRichterOkrusch1989, author = {Sch{\"u}ssler, Ulrich and Richter, P. and Okrusch, Martin}, title = {Metabasites from the KTB Oberpfalz target area, Bavaria - geochemical characteristics and examples of mobile behaviour of "immobile" elements}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-31021}, year = {1989}, abstract = {No abstract available}, language = {en} } @article{KreuzerSeidelSchuessleretal.1989, author = {Kreuzer, Hans and Seidel, Eberhard and Sch{\"u}ssler, Ulrich and Okrusch, Martin and Lenz, Karl-Ludwig and Raschka, Helmut}, title = {K-Ar geochronology of different tectonic units at the northeastern margin of the Bohemian Massif}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-31811}, year = {1989}, abstract = {No abstract available}, language = {en} } @article{Schuessler1993, author = {Sch{\"u}ssler, Ulrich}, title = {Zur geologischen Situation der Erzlagerst{\"a}tte Kupferberg-Neufang in der Umrahmung der M{\"u}nchberger Gneismasse}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-31791}, year = {1993}, abstract = {Die Kupfer-Zink-Lagerst{\"a}tte von Kupferberg-Neufang im Bereich der M{\"u}nchberger Deckenstruktur besteht aus einem etwa 4 km langen Zug einzelner stratiformer Vererzungslinsen, der in NW-SE-Richtung vom anchimetamorphen Pal{\"a}ozoikum "Bayerischer" Faziesentwicklung in die Prasinit-Phyllit-Serie hin{\"u}berzieht.

The pegmatite mineral assemblage consists of K-feldspar, plagioclase, quartz, garnet (almandinespessartine-pyrope), dark tourmaline (schorl-dravite), muscovite, apatite, monazite, zircon, blue AI-rich tourmaline and dumortierite in order of decreasing abundances. Major, minor and rare earth elements are reported for the greater part of the mineral assemblage. The time of pegmatite emplacement is constrained by Rb-Sr and Sm-Nd isochron ages of 492 ± 8 (2a) Ma and 500 ± 40 (2a) Ma, respectively. High initial 87Sr/86Sr of 0.7315 ± 0.0003 and low E Nd,t of -8.7 ± 1.2 strongly support an origin of the magma from highly evolved crustal source rocks. K-Ar and Ar-Ar model ages of about 470 to 475 Ma for igneous muscovite indicate that the pegmatite together with its wall rocks spent a prolonged period at elevated temperatures before final cooling below about 350 °C. The muscovite dates may give an estimate for the time of exhumation of the Oates Coast crystalline basement along two major late Ross orogenic detachment zones within the Wilson Terrane i.e. the Wilson and the Exiles thrusts (c.f.
