Interesting geology at Szentbékkálla

The Szentbékkálla region is interesting from geological aspects. The volcanism at the Bakony–Balaton Highland Volcanic Field produced beautiful scenic mountains which preserved the elevations of the Pliocene plains. The basalts contain various xenoliths. Among the xenoliths there are igneous inclusions genetically related to basalts. Genetic and textural characteristics of the host basalt and some of its inclusions are analog from Szentbékkálla, North-Balaton Mountains,

Short origin history of lherzolites of Szentbékkálla

It was found 150 years ago, that basalts of the Balaton-Highlands contain "

. Petrographic research all over the world studied mantle xenoliths and it was found, they are the source rocks for basalts: the basalts are partial melts of the mantle rocks. During the upheaval process the basaltic liquid carries up the fragments of the upper mantle. Several other igneous xenoliths are also related to the upper mantle and basalts. That is the short explanation of the sequence of various upper mantle xenoliths inside the basalts of Szentbékkálla.
