Abstract
The Mid-Hungarian (or Zagreb-Zemplin) Line of WSW–ENE strike divides the Pannonian
basement into two mega-units, the Tisia Composite Terrane in the SE and the ALCAPA Composite
Terrane in the NW. They became juxtaposed no earlier than the Middle Miocene (Karpathian). Their
present adjacent zones show very different Variscan and Alpine evolution and relationships, which
are briefly reviewed here and confronted in the light of detailed correlational work published during
the last decade. The present contribution summarizes Variscan and Alpine evolution of units/terranes
juxtaposed along the Mid-Hungarian Line, the major terrane boundary in the pre-Neogene basement
of the Pannonian Basin, as can be seen on the Circum-Pannonian terrane maps
