Sažetak
The boundary area between the Alps, Dinarides and Tisia provides a remarkable opportunity to test and improve the current knowledge on the orogenic history of the European Alpine belt. This is mostly due to the fact that the three major tectonic boundaries join here: the Periadriatic Lineament, a collisional scar that separates the Austroalpine units and the Southern Alps; the Zagreb-Zemplin (Mid-Hungarian) line, a southern boundary of the Zagorje-Mid-Transdanubian (Mid-Hungarian) zone that separates two major basement blocks of the Pannonian Basin (Alcapa and Tisia) in the Neogene, and the Vardar zone, the most internal unit of the Dinarides. Precise locations of these boundaries and their kinematic history in this area, however, are still ambiguous due to a complex Neogene deformation and a thick southern Pannonian Basin cover. In this report a short overview on the major pre-Neogene tectonostratigraphic units of the boundary area is presented. These units sporadically crop out on a few isolated, up to thousand meter high mountains of Ivanščica, Kalnik, Žumberak, and Medvednica, the last one being included into the PANCARDI 2000 field trip. The major pre-Neogene tectonostratigraphic units are: 1) The Late Paleozoic-Mesozoic volcanic-sedimentary complex which crops out on Mt. Ivanščica, strongly dismembered along the easternmost tip of the Periadriatic Lineament; 2) The Cretaceous ophiolitic mélange, a chaotic unit characterized by a pervasively sheared shale-silty matrix, containing fragments of predominate native graywackes, ophiolites, radiolarites, shales and exotic limestones; 3) The Early Cretaceous low-grade metamorphic complex which crops out on central, southern and northeastern part of Mt. Medvednica, derived from a volcanic-sedimentary complex of Paleozoic-Triassic age; 4) The Late Cretaceous-Paleocene transgressive to basinal formations that crop out along the main ridge of Mt. Medvednica unconformably overlying both the metamorphic and ophiolitic mélange complexes, and 5) The Mesozoic platform to basinal formations of the Žumberak-Medvednica nappe that form the highest structural unit of the pre-Neogene structural assemblage.
