Abstract

The greatest part of the Pre-Neogene basement of the Pannonian Basin is built up by two Alpine megatectonic units, the Pelsonia Composite Terrane in the N, forming the southern part of the ALCAPA Composite Terrane, and the microcontinent-sized Tisia Terrane in the S. They are separated by the Zagreb-Zemplin or Mid-Hungarian Lineament, which likely merges E of the Danube River with the ENE-ward continuation of the Periadriatic-Balaton Lineament. The crustal blocks/terranes of the basement and of the rest of the ALCAPA C.T. form a true orogenic or terrane collage, framed on the E-SE, resp. SW by two deformed, but unbroken Neotethyan continental margin domains: the Median Dacidic (or Bucovino-Getic) - Serbo-Macedonian (i.e. Carpatho-Balkanide) margin on the E and SE and by the South Alpine - Outer Dinaridic (i.e. Adriatic or Apulian) margin on the SW (although the former was partly separated from the European foreland in course of the Late Jurassic - Early Cretaceous by the narrow Outer Dacidic or Civcin-Severin Rift Zone). These two domains enclose the main Neotethyan suture zones of the Axios/Vardar and Maliak-Mirdita-Dinaridic Ophiolite Belt zones, bifurcating in the present setting at the southern margin of the Tisia Terrane. In the first chapter of the present review a short history of the terrane concept and of the recognition of the heterogeneous block structure of the Pannonian basement is given, followed by some methodology. In the main chapter the major terranes of Hungary (Pelsonia and Tisia, i.e. their Hungarian part) are described, concerning their Variscan and Alpine sedimentary, magmatic, metamorphic and (up to a certain extent) tectonic evolution. Palaeomagnetism is analysed in a separate contribution (Mŕton, present volume), whereas for a latest review of Mesozoic (especially Jurassic) palaeobiogeography we refer to Vörös (1993). Terranes of the Eastern Alps (Austroalpinia, Penninia) and of the West Carpathians (Veporia, Zemplenia), extending only a small amount into the territory of Hungary, are only briefly characterised, not described in detail.
