Aertemeishibulak Fm

Period: 
Devonian

Age Interval: 
D3(?) (16); Late Devonian


Province: 
Xinjiang

Type Locality and Naming

Eastern Tarim Basin. The type section is located on the 898 m Highland, southeast of Aertemeishibulak, south of Bosten (Bagrax) Lake and Xinggir in the Xinjiang Uygur Autonomous Region. It was named by No 13 Geological Team of Xinjiang in 1957 and was published by the Compiling Group of Xinjiang Regional Stratigraphical Scale (1980).


Lithology and Thickness

Sandstone. It is mainly characterized by interbedded purplish-red to purple thick-bedded sandy conglomerate, pebble-bearing sandstone and coarse-grained sandstone, with intercalations of layered arkosic quartzose sandstone at the lower part; the purple sandstone often contains calcareous concretions. The thickness is 1201-1299 m.


Lithology Pattern: 
Coarse-grained sandstone


Relationships and Distribution

Lower contact

Conformable contact with the underlying Shugouzi Fm of the middle Devonian [which was not included in English version of Lexicon]

Upper contact

Unknown: It has an obscure contact with the overlying Lower Carboniferous.
