Synonym: Zulumart Suite, зулумартской свиты, Karachatyrsky, Ulyuk, and Kuberkand horizons

Reference section:

Composed of black slate-like limestones and light massive reef limestones that mix facies. Thickness 100-800 m.

In the lower part of the Zulumart Fm (зулумартской свиты), there are calcareous-sandy shales and fine-grained sandstones with a thickness of 100 M, containing lenses of clayey limestones and conglomerates. At the top of the section, there is sometimes a package composed of alternating green and purple sandstones, shales, gravelites, conglomerates, and limestones. Thickness 150 m. E. Ya. Leven (1967) singles it out as a separate "variegated" suite. However, it is also replaced by light reef limestones and is therefore included in the Zulumart Fm by M. I. Shabalikin.

The lower parts of the Zulumart Fm (зулумартской свиты) are characterized by the remains of foraminifera Staffella sphaerica (Abich.), Quasifusulinia nimia Koch. - Dev., Robustoschwagerina tumida (Lich.), Darvasites Ordinatus (Chen), D. zulumartensis Lev., Rugosofusulina vulgariformis Kalm., Pseudofusulina acuteata Lev., Parafusulina pamirica Lev., P. zulumartensis Lev., P. murotbekovi Lev. E. Ya. Leven (1967) considers them characteristic of the upper part of the Karachatyr horizon. The middle part of the suite is characterized by numerous fusulinids of the Uluk horizon Pseudofusulina nalivkini Lev., Ps. kraffti (Schellw. et Dyhr.), Ps. magna Tor., Ps. procera Lev., Parafusulina incognita Lev., P. zulumartensis Lev., etc. At the top of the suite is the Kuberghandinsky complex of fusulinids: Parafusulina yunnanica Sheng., P. yabei asiatica Lev., Misellina olgae Lev., M. cf. dyhrenfurthi (Dutk.), M. ovalis (Depr.), Cancellina sp., Armenina salgirica M.-Maclay, etc.
