Involutina farinacciae Bronnimann & Koehn-Zaninetti 1969, a marker for the Middle Liassic in basinal and some platform facies of Mediterranean and near east areas: The discussion concerning the paleogeography of Montenegro-Albania border region (the Scutari-Pec lineament)

Abstract

Foraminiferal species Involutina farinacciae BRONNIMANN & KOEHN-ZANINETTI, is a marker of Middle Liassic basinal and transitional platform bassin facies widely distributed in Mediterranean area (Umbria-Marche, Pindos, Budva, Sicilia and the Inner Dinarides basin), also in Iraqi Kurdistan (“Avroman” Basin). In the Dinaric Carbonate Platform (DCP) it indicates intramarginal and intraplatform depressions. Paleogeography of the Montenegro-Albania border area formed by the inherited prealpine paleogeographic scenario that resulted in a different arrangement of the paleogeographic units westward and eastward of the paleostructure (Scutari-Pec Lineament) which controlled the geological history of the region. This transverse paleostructure was a) coincident with the paleogeographic front of the DCP, and b) the westward limit of the overtrusted Mirdita Zone. The difference in the paleogeographic features in the prolongation from the DCP througout Albania, controlled by paleostructure, are the source of seizmicity, rotation and deviation (SE to NW, into NE) of the Complex Mirdita Zone.
