TRIASSIC RADIOLARIANS FROM THE DARNO AREA (HUNGARY)

Radiolarites belonging to the Darno series and interbedding within hyaloclastites and basalts yielded radiolarians of Triassic age: Ladinian (-Carnian). These data prove that volcanic activity was effective at least as early as mid-Triassic times and revealed, by the same way, some affinities between Darno and Tethyan sequences. Des radiolarites appartenant aux series de Darno intercallees dans des hyalocla-stites et des basaltes ont livre des radiolaires triasiques: Ladinien (-Carnien). Ces don-nees montrent qu'une activite volcanique existait des le Trias moyen confortant ainsi le rapprochement effectue entre series de Darno et series tethysiennes
