The overlying Lumshival Formation consists of white quarz arenitic lithofacies, bioclastic limestone facies and glauconitic sandstone
lithofacies which resulted from delta front to inner ramp depositional setting.
Provenance: Low silisiclastic contents in the green sandstone indicate a distant or low relief source, but the presence of the glauconitic sandstone
suggests intermittent influxes of coarse silisiclastic material, possibly by turbidity current (Plates 7 and 8).
One can find the phosphatic Obolus sandstone, including brachiopod bivalves and fragments, radioactive alum shale, glauconite-rich gray bentonite clay and glauconitic sandstone
Fewer than 60 specimens assigned to 18 species were previously recorded from the calcareous glauconitic sandstone
of the Maekula Member (Schmidt 1904, 1907; Lamansky 1905; Opik 1937; Balashova 1961, 1966).
At the upstream end of the section, hard, very fossiliferous glauconitic sandstone
forms a shoal across the channel (Locality 1).
2 showed some glauconitic sandstone
about 60 meters above the base of the formation.
and carbonaceous shale with occasional belemnite and ammonite were taken into account to mark the Chichali Formation.

It may be concluded that glauconitic sandstone

The outcrop studies reveal that the Chichali Formation is composed ofthree facies; the base ofChichali Formation is composed ofFine Grained Sandstone Facies, which shows the deltaic or deltaic beach deposition, Glauconitic Sandstone
Facies is present in the middle part ofthe Chichali Formation, which is characterized by the presence ofsubstantial amounts ofglauconite and thus believed to be deposited in the deeper shelfal environment, and the upper part of Chichali Formation is comprised of Glauconitic Dolostone Facies, which represents deposition on mixed elastic-carbonate dominated shelf.
