by Altovsky (1958). He believed that the Mesozoic rocks exposed in the
Great Balkhan and Kopet-Dag were the charge area of the Balkhan area's
Red-Bed sequence.
Specifics of the geologic structure over the southeastern plunge of the
Caucasus Major Meganticlinorium are:
t
Its step-block nature (the Tengin, Khizin and Kovdag steps).
t
Commonality of high-amplitude regional faults (the Siazan,
Karabulak, Germian, Zangin, Keshchay and Yashmin).
t
Contact between heterochronous stratigraphic units across
these faults.
t
Drastic deformations of the local structures (Figure 5.4).
t
Common development of flysh facies.
