and the Menderes Massif. The
morphotectonic configuration of
Anatolia and the
Aegean is a result of
continental drift movements associated with the
Alpine orogeny, a zone of mountain-building caused by the collision of the
African and
Arabian Plates with the
Eurasian Plate. The former have been slipping under the latter compressing and lifting the edge and creating zones of
metamorphic rock from previous layers of
sedimentary rock. These zones in the Aegean are represented by a number of
massifs that were originally buried by crustal
subduction: the
Rhodope, Kazdag, Menderes,
Cycladic Massif and Crete. For various geologic reasons, modelled differently by different geologists, the zone of compression in the Aegean became one of
extension: the region widened and dome-like or ovoid massifs were uncovered, or exhumed, from the subduction zones and rose by
isostasy. In the case of the Menderes Massif, which is , the reasons are better known due to geologic research in central Turkey. Anatolia is a triangular block created by the intersection in central Turkey of the North and East Anatolian faults. As the northward-pressing Arabian Plate pushes against this wedge the latter slips to the west but the broad end opens along fault lines like the rays of a fan, extending the massif to the north-northeast and south. This is being called a bivergent (diverges in two places) model. The entire massif is divided or nearly so by a
karst topography into three sections: the Gordes Massif north of the Alasehir or
Gediz graben, the Cine Massif south of the
Büyük Menderes graben and the Central Massif between. The latter is split like a forked tongue by the
Küçük Menderes Graben into the Kuzey Detachment to the north and the Guney Detachment to the south.
Mycale is part of the Guney Detachment, while Latmus is in the Cine Massif. The Graben are low-key
rift valleys. There have been some small intrusions of
magma into the graben appearing now as granito-diorite outcrops. Dates on thin sections of
monazite obtained from the earliest exhumed rocks of the graben suggest "... that the Cenozoic extension in the Gordes Massif, and possibly the entire Menderes Massif, might have begun in the
Late Oligocene." Despite the rare intrusions, the massif is not of volcanic origin. Most of the visible layer is light, metamorphic rock of various kinds, especially
marble and
schists. Except for
alluvial fans of impermeable
clay the rock is highly porous due to a network of small faults, which dips into the warmer regions below the surface. Warm springs and vapors are common, giving the appearance of volcanic activity. The ancients cross-culturally viewed these phenomena as being caused by divinities, which rock-paintings indicate they worshipped. The north slopes of Latmus are subject to heavy and damaging mudslides, which also would have contributed to the idea that it was a god. ==Mythology==
