The Mamonia Zone or Complex constitutes a diverse and structurally complex assemblage of igneous, sedimentary and metamorphic rocks, ranging in age from Middle Triassic to Upper Cretaceous (230-75 Ma). These rocks, which are regarded as allochthonous in relation to the overlying autochthonous carbonate successions and the Troodos ophiolite rocks, were placed over and adjacent the Troodos ophiolite during the Maaistrichtian. They occur only on the southern part of Cyprus with extensive outcrops in the Pafos region.
The stratigraphic classification of the Mamonia Complex poses problems, however three main groups can be recognized.
I. Volcanic (lavas) and sedimentary rocks (recrystallised limestones) of the Diarizos Group.
II. Pelagic sedimentary rocks (limestones, mudstones and quartzitic sandstones) of the Agios Fotios Group.
III. Metamorphic rocks (schists and marbles) of the Agia Varvara Formation. These rocks were derived from the metamorphism of the Diarizos Group.
The high degree of deformation and alteration in combination with the clays and steep topography is considered some of the factors for instability in the Pafos region. In addition, earthquakes have played (and still play) their own, very significant role.
