Abstract
Upper Lower Paleozoic basic volcanism, probably caused by synsedimentary tectonics, and the extensive Eifelian hiatus on the Iran plate are regarded as late Epicaledonian events in an epicontinental facies area. During the time interval Givetian-Visean a miogeosynclinal development increased while marine facies transgressed into a subsidence area in the northwest and regressed from an uplift area in the south. A general Upper Carboniferous regression with an unproven metamorphism of the southern ridge and a probable uplift of a Pre-Rhaetian land area in the northeast, and the following Permian transgression, predominantly again towards the northwest, were syn- and postorogenetic. The events since the Givetian were introduced from the Hercynian geosyncline and orogeny of the adjacent Eurasian Turan Plate, against which the Iran Plate rotated by steps in a slight clockwise turn. This geotectonic interpretation of the late Paleozoic paleogeography is comparable with that of the geomagnetics.
