Petrochemical character of the Lower Cretaceous rocks of the Great Hungarian Plain
Originally the Lower Cretaceous volcanics of the Great Plain proved to be olivine-free, pyroxene-bearing and feldspar-rich basaltic rocks. The initial magma was of tholeiitic composition. The volcanics were erupted in seawater and subsequently spilitized and auto-metasomatized. At the Lower and Uppe...

| Tartalmi kivonat: | Originally the Lower Cretaceous volcanics of the Great Plain proved to be olivine-free, pyroxene-bearing and feldspar-rich basaltic rocks. The initial magma was of tholeiitic composition. The volcanics were erupted in seawater and subsequently spilitized and auto-metasomatized. At the Lower and Upper Cretaceous boundary the rocks were uplifted and endured epigenic alteration. Their genesis is related to an early Cretaceous rift formation. |
