Egy összetett kitörési eseménysorozat nyomai a Bükkalján (Észak-Magyarország): a Kács Egység
Signs of complex eruption events at the Bükk Foreland (Northern-Hungary): the Kács Member

Bükkalja, freatomagmatizmus, paleomágnesség, piroklaszt-szórás, granulometriaAbstract
A stratified, complex volcanic succession occuring at Kács (Bükk Foreland Volcanic Area, Northern-Hungary) belonging to the Lower Pyroclastic Complex was documented in detail in this work. The tephra-generating volcanic processes were inferred based on the volcanological and granulometric features of the deposits as follows: at least three Plinian eruptions (I-III) produced fallout tephra separated by paleosol horizons recording inter-eruptive quiescence periods. Several features of the earliest eruption sequence suggest a phreatomagmatic eruption style. Regional correlation attempts are supported by paleomagnetic rotation data, which helped the classification of the sequence right below to the Middle Pyroclastic Complex.
