Kyzylpilyal Formation

Kyzylpilyal Fm

Period:

Cretaceous

Age Interval:

Lower Cenomanian, S3, S5

Province:
North Tajik

Type Locality and Naming

Synonym: Kyzylpilyal suite

Reference section:

Lithology and Thickness

Clays, sandstones. It is represented by red and gray clays, sandstones, and conglomerates with layers of nodular limestone in the lower part. The total thickness is 14-22 m (Sochava, 1968).

Lithology Pattern:

Clayey sandstone

Relationships and Distribution

Lower contact

Lower Cretaceous formations

Upper contact

Regional extent

In the northeastern part of the Turkestan district in the basin of the river Isfara, the Lower Cenomanian (Tubegatansk and Karikansay horizons) (тюбегатанский и карикансайкий горизонты) corresponds to the upper part of the Kyzylpilyal Fm

Fossils

In the synchronous deposits of Southeastern Fergana, Early Cenomanian foraminifers Rotaliatina asiatica N. Byk. * are found.

In the lower half of the Kyzylpilyal Fm, remains of nonmarine ostracods Timiriasevi polymorpha Mand., T. principialis Lubimova (Sochava, 1968) were found. In the upper part of the Kyzylpilyalskaya suite, remains of marine ostracods of the genus Neocythere were found, and in its analogs in Southeast Fergana, remains of early Cenomanian foraminifera were found. The presented information allows us to suggest that in the northeastern part of the Turkestan and in the South Fergana region, we are dealing only with the tops of the Lower Cretaceous section, most likely of Albian age.
