The South Caspian Basin
The present-day South Caspian Basin (SKB) (the Pliocene-Quaternary

areas of the Eastern Azerbaijan, Western Turkmenistan and Northern
Iran (Figure 1.1). It is bounded in the north by the Derbent-Krasnovodsk
deep-seated fault, in the west by the Talysh-Vandam gravity maximum,
in the east by the Aladag-Messerian tectonic step and in the south by the
folded mountainous structure of Elburs. The basin's areal extent is about
160,000 km 2 , the volume of its sedimentary fill is approximately 2.7
