Abstract

In the northern part of the Tisza Superunit (Hungary), the vajta-3 borehole crosscuts basement rocks. The Al-rich metapelites contain contrasting mineral assemblages: an older kyanite + staurolite + almandine assemblage, which may be referred to a Barrovian-type metamorphic event, and a younger andalusite + biotite + (almandine) assemblage, indicating a low-pressure event. In spite of the complete lack of geochronological data, a two-stage metamorphic history for the Tisza Superunit does fit the picture emerging from the literature for the whole Hungarian basement.
