Tartalmi kivonat: | Based on exploration carried out by deep-drillings near Bár village a small maar-like volcano covering by Quaternary loess and characterized by a sole eruption is proved. Producing a fairly well determinable thin volcanic sequence this eruption is represented by a very thin tuffaceous sheet on the base of the volcanic succession and a scoria member and a porous, sometimes churned rarely compact basaltic lava mass. The basalt is classified as a leucite basanite turning into analcitebearing basanite at the margins and at some places of the porous inner sections of the volcanic body. Being a conspicuous petrologic difference between Pannonian basalts of Hungary and Bár alkaline rocks, the latter is regarded as an independent volcanic event of the great Pannonian volcanism of Hungary. |
