The formation is named after Mount Kurek (2,280 metres (7,480 ft)), near Langar, Uzbekistan.[2]

Description

The mudstones and limestones of the formation comprise a 2 centimetres (0.79 in) thick, massive micrite (mudstone) with sporadic and poorly preserved thin-walled bivalves. Also tracks were preserved at that were probably made in shallow water, showing, in some parts, ripple marks.[3]
