“…They consist of numerous subgrains, mainly in their marginal parts. A number of clinopyroxene and amphibole megacrysts were found at L1, which have the same appearances and textural features as the well-studied clinopyroxene and amphibole megacrysts commonly found in other alkaline basaltic volcanics from the Bakony-Balaton Highland Volcanic Field (e.g., Embey-Isztin et al, 1990;Dobosi et al, 2003a;Jankovics et al, 2013Jankovics et al, , 2016. They generally occur together with pyroxenite (Type II) xenoliths consisting of clinopyroxene + olivine + spinel ± amphibole.…”

“…11 surface. These earlier magmas stalled and accumulated in the uppermost part of the lithospheric mantle, near the crust-mantle boundary and crystallized as veins, dykes and sills characterized by compositions very similar to those representing the host alkaline basalts (e.g., Embey-Isztin et al, 1990;Dobosi et al, 2003a;Jankovics et al, 2013Jankovics et al, , 2016. Considering the co-existence of the above-mentioned large olivine grains with a clinopyroxene megacryst in our studied sample, and the appearance of the large type III olivine cores (textural features implying disaggregation; Fig.…”

“…The textural, zoning and compositional characteristics of clinopyroxene in petrologically and geochemically diverse volcanic and plutonic rocks have been extensively studied over the past 40 years (e.g., Wass, 1979;Duda and Schmincke, 1985;Dobosi et al, 1991;Dobosi and Fodor, 1992;Neumann et al, 1999;Nakagawa et al, 2002;Streck et al, 2002;Marks et al, 2004;Shane et al, 2008;Stroncik et al, 2009;Winpenny and Maclennan, 2011;Jankovics et al, 2012Jankovics et al, , 2016Ubide et al, 2014a, b;Gernon et al, 2016). These detailed mineral-scale studies have inferred the origin of different clinopyroxene populations, from open-and closed-system petrogenetic processes operating in subvolcanic magma storage systems to the evolution and ascent histories of different magmas (replenishment, magma mixing, mingling, xenocryst incorporation, fractional crystallisation and contamination).…”

“…A Pannonmedence alkáli bazalt területei kiváló lehetőséget nyújtanak, hogy a monogenetikus vulkáni mezők természetét jobban megértsük. Ehhez új szempontot és eredményeket adnak a nagy felbontású, kristályalapú szöveti és geoké miai kutatások (HARANGI et al 2013(HARANGI et al , 2015JANKOVICS et al 2013JANKOVICS et al , 2015JANKOVICS et al , 2016JANKOVICS et al , 2019SÁGI et al 2018), amelyek feltárták, hogy egy bazaltvulkáni mező működése is sok esetben komplex folyamatok eredménye. A bazaltos magmák meg akadhatnak a földkéreg és földköpeny határán, akár hosszú időn keresztül is fennállhatnak, és a különböző fejlettségű magmák keverednek egymással.…”
