- 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-basalticVarious 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.

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.…
