Complex folding makes detailed interpretations of the geological structure difficult, but the area essentially consists of a large, tightly folded syncline that strikes about N.20 [degrees] E.
At several localities a west-verging footwall syncline has developed as a consequence of westward transport on the overlying thrust sheet.
A series of transverse anticlines and synclines are observed that have axes orientated NE-SW, approximately perpendicular to the fault zone.
A series of synclines and anticlines developed within the basin at several localities but most prominently south of the Aghios Georgios fault zone.
In the northwestern part of the chain, the arches are neatly separated by the Almazan basin, which has a complex synclinal structure, but they merge towards the SE.
The tendency towards hydrostatic equilibrium would force magma updip beyond the synclinal axis, and cause the greatest thickness of magma to accumulate at the bottom of the sill.
Selenite mostly formed in shallow marginal settings and was redeposited into a small remnant basin with a depocentre near the present synclinal axis.
The faults have a systematic geometric relationship with folds, with anticlines in the mutual hanging walls of fault pairs and broader footwall synclines that define the shallow dish forms of the polygons.
Local unconformities and deposition in the foreland basin and intra-mountain synclinal basins occurred in discrete phases.
It is distinguished from adjacent terranes of similar age by its open synclinal structure, obviously fossiliferous character, the thickness of essentially conformable strata, and the predominance of volcaniclastic rocks.
