The orientation, asymmetry and cross-cutting relationships of the structures along the contact zone between the Lycian nappes and the Menderes Massif suggest the presence of three deformation phases in the Milas region of southwest Turkey. The first deformation phase (D1) is characterized by a ductile deformation with top-to-the-NE sense of shear. Structural data of the first deformation measured along the uppermost part of the Menderes Massif and the base of the Lycian nappes suggest that the lowermost unit of the Lycian nappes was emplaced initially from southwest to northeast onto the Menderes Massif during the Early Eocene. The second deformation phase (D2) is also ductile in nature and is characterized by an E-W-trending stretching lineation with a bivergent sense of shear, which is probably related to the load of the overlying nappes. A third deformation phase (D3) is characterized by south-dipping normal faults with top-to-the-S sense of movement. This third deformation phase can be related to southward movement of the Lycian nappes along a low-angle decollement zone. The tectonic contact between the Menderes Massif and the Lycian nappes and their strongly-deformed rocks are unconformably covered by approximately flat-lying, coal-bearing Early-Middle Miocene sedimentary rocks, which constrains the upper time limit for all three deformation phases.
