Relationships and Distribution
Lower contact
It lies with a distinct angular unconformity on the Paleozoic and Mesozoic beds.
Upper contact
It is conformably overlain by red-colored rocks of the Yamantash Fm -Tashkulyak Fm (яманташской-ташка.11якской свит), conditionally of multi-age.

Age
On the basis of fossil data which its Paleogene age is presumably determined (Gusev, 1972; Gusev et al., 1972). Hence for schematic stratigraphic representation it is considered as Chattian for lexicon.
