Karategin Gr

Period:

Archean

Age Interval:

Eoarchean – Neoarchean (AR? Kr), C3

Province:
Central Tajik

Type Locality and Naming

Lakhsh (formerly Jirgatol) District — officially renamed in 2016 — is located in northeast Tajikistan, and includes the village of Mugh (formerly Muk) within its administrative jamoat Lakhshi Bolo (Wikipedia, 2025; RFE/RL via Asia-Plus, 2016; Wikipedia: Mugh; Wikipedia: Lakhshi Bolo).

Synonym: Karategin Suite, Каратеrинская серия

Reference section:

Lithology and Thickness

It consists of gneisses, crystalline slates, and migmatites. In interlayers, there are marbles, epidotes, granulites, and amphibolites. The incomplete thickness is 3000 m. Among the gneisses, there are biotite, garnet-biotite, Cordierite, sillimanite, and amphibole varieties are found among the phyllites, including biotite, garnet-staurolite-biotite, and amphibole types. The stratigraphic subdivision of the Karategin series has not been carried out due to the exceptionally high content of migmatites, gneiss-granites, and granites in the rocks. The series has a two-membered structure: in the upper third of its section, calcite and dolomite, rarely magnesite, marbles play a noticeable role, which are almost absent in the lower parts of the series section (Korovkin and Shadchinev, 1959).

Relationships and Distribution

Lower contact

The relationships of the Karategin series with the surrounding rocks have not been clarified.

Upper contact

The relationships of the Karategin series with the surrounding rocks have not been clarified. In this work, the view of M. M. Kukhtikov (1956a); A. I. Lavrushevich and D. R. Muchaidze (1960); R. B. Baratov et al. (1970a); N. A. Popova, Yu. N. Nuyskov, S. S. Lima, and V. T. Vashurov (1971) is accepted, who consider the contacts of the Karategin series with the surrounding Paleozoic to be tectonic. At the same time, A. S. Shadchinev, O. G. Zhirnov, and A. E. Drannikov (1970) believe that there are gradual transitions from crystalline rocks to paleontologically characterized sediments of the Middle Devonian.

Regional extent

It is distributed in the Karategin region. Also distributed in the Muxuy, Lakhsh district.

Age

Eoarchean – Neoarchean. In the light of data on the age of the Karategin Gr and the nature of its metamorphism, this conclusion seems less likely.
