Especially for the Mariänske Läzne metabasic complex, confirming early Czech determinations, the dates resemble the early Devonian pattern determined for the Münchberg Gneiss Massif and the Erbendorf-Vohenstrauß zone of northeastern Bavaria. This supports the idea that all three units are remnants of a huge complex which suffered a metamorphic overprint under medium-pressure conditions, probably in the early Devonian. Streng rejuvenation is found in the southern part of the Teplä-Domailice zone by which micas and even two hornblendes were reset to mid-Carboniferous ages. According to the geological setting, part of the apparently preDevonian dates may be explained by inherited argon from earlier metamorphic and magmatic events, e.g. the high-pressure metamorphism documented in eclogitic relics. However, excess argon, caused by the mid-Carboniferous overprint cannot be excluded. 1988 urn:nbn:de:bvb:20-opus-87527 Institut für Mineralogie und Kristallstrukturlehre OPUS4-7214 Konferenzveröffentlichung Schüssler, Ulrich; Vejnar, Z.; Okrusch, M.; Rose, S.; Seidel, E. Geochemistry of Metabasites and gabbroic rocks from the Tepla-Domazlice zone Various amphibolites, metagabbros and eclogitic relics of the Mariänske Läzne complex, and amphibolites from the Cernä Hora Massif exhibit an uniform geochemical character which compares weil with modern mid-ocean ridge basalts. Geochemically these metabasites are similar to the amphibolites of the Myto area and to schistose, partly striped amphibolites of the neighbouring Tirschenreuth-Mähring Zone and the Erbendorf-Vohenstrauss Zone (Bavaria). Greenschists and amphibolites from the Domazlice metamorphic complex show an alkaline-basaltic tendency conforming to modern within-plate basalts or basalts from anomalaus midocean ridge segments. In their chemical character, these metabasites compare weil with the flaseramphibolites of the Erbendorf-Vohenstrauss Zone. Fine-grained amphibolites in the Warzenrieth area and (gabbro-) amphibolites in the Blätterberg-Hoher Bogen area show normal MORB character. The metamorphosed gabbroic rocks in the southern part of the Neukirchen-Kdyne (meta-) igneous complex are subalkaline - tholeiitic and exhibit a magmatic differentiation trend. They differ from the neighbouring amphibolites by generally lower contents of incompatible elements. 1988 urn:nbn:de:bvb:20-opus-87511 Institut für Mineralogie und Kristallstrukturlehre OPUS4-7207 Konferenzveröffentlichung Kreuzer, H.; Henjes-Kunst, F.; Seidel, E.; Schüssler, Ulrich; Bühn, B.
