Period:

Quaternary

Age Interval:

Neopleistocene (Calabrian), F1-F10f

Province:
Fergana

Type Locality and Naming

Along the Soh River, a tributary of the Syr Darya, Fergana Valley. N.P. Vasilkovsky, 1935 (128, p.22), as a denudation phase; G.F. Tetyukhin, 1961 (469a, p. 386-388) as a complex. Stratotype along the Soh River, Fergana Valley.

Synonym: Sox Complex, Сохский компл.

Lithology and Thickness

In the stratotype, large-pebble conglomerates of the adyr zone. In the foothill and plain zones, often replaced by pebbles, sands, marls, loams with intensely carbonated loess (shokh). Thickness 15-200m.

Lithology Pattern:

Aus Conglomerate

Relationships and Distribution

Lower contact

Lies with erosion, sometimes with azimuthal and stratigraphic discordance on rocks of different ages.

Upper contact

In the mountainous part, preserved in the form of terraced ledges, while in the foothills and plains, overlain by sediments of younger age.

Regional extent

Fergana Valley. Widely distributed along almost all major watercourses in the mountainous and foothill zones. Correlated with the Nanai complex of the Prishashkent region, lower parts of the Zarkent suite, and subaerial loess.
