Reference section:

Lithology and Thickness

According to S. S. Kara petov (1964), the section of the described deposits is three-membered. The lower part of it (15 m) is made up of red-colored sandstone limestones and sandstones. The middle part (50 m) is composed of limestones. The upper part (80-100 m) is made up of dolomites. The total thickness of the considered Upper Carboniferous - Permian deposits is about 160 m.

Lithology Pattern:

Sandy limestone

Relationships and Distribution

Lower contact

They lie with an unconformity on the limestones of the Moscovian stage of the Middle Carboniferous.

Upper contact

Regional extent

It is exposed in the Central Pamir in the Akbaytal and South Rangkul tectonic slices.
