Sallyatash Formation

Sallyatash Fm

Period:

Carboniferous

Age Interval:

Lower Carboniferous (Visean), CK9-9b

Province:
Chatkal-Kuramin Region

Type Locality and Naming

Along the Salliyatash Mountain, SouthwesternKaramazar, western end of the Kuramin Range. Zh.N. Kuznetsov, Yu.S. Shikin in 1960 (460, p. 157). The holostatotype is not specified; a composite section is proposed as the lectostatotype (due to strong tectonic disturbance). Lower-middle part - Along Mt. Shirabad (Almalyk), upper part - Along the section in the Kulchulak mine area. Initially (382; 457) the Sallyatash Fm was mistakenly considered as a component of the Tashgezek Fm (Tkachev et al., 1988, 1996).

Synonym: Sallyatash Suite, Салляташская св.

Lithology and Thickness

The suite is divided into three parts. Lower - medium-thin-bedded organogenic-detrital, detrital-muddy limestones with inclusions of cherts in the form of nodules, lenses, and interlayers with numerous coral and tabulate remains. Middle - thin-bedded siliceous rocks, interbedded with siliceous-clayey, siliceous-carbonate varieties. Upper - medium-bedded muddy limestones with rare detritus and rare siliceous inclusions. Thickness 110-200m.

Lithology Pattern:

Clayey limestone

Relationships and Distribution

Lower contact

Conformably overlies the Saukbulak Fm and Aktash Fm

Upper contact

Conformably overlain (in complete sections) by the Kulchulak Fm (Almalyk region) or the Tashgezek Fm (Altyn-Topkan).

Regional extent

Kuraminsky Ridge, interfluve of the Urgaz-Karakia rivers, Kalkanata, Altyn-Topkan, Baraktyntau mountains.
