Unit

Thickness

Description

Unit 6

28 ft.

Thin laminated sandstone ended by short cycles of coarsening upward tidal bars with internal flaser bedding indicating tidal flat environment

Unit 5

36 ft.

Consists of massive to faintly laminated with some fining upward ripple sandstone and ended by coarsening upward cycle of forest tabular cross bedding suggesting tidal bars and/or tidal delta

Unit 4

10 ft.

Thin laminated hetrolithic bioturbated facies with dispersed pyrite and directly deposited over the underlying tidal channels

Unit 3

43 ft.

Consists of two fining upward cycles interbeded with small coarsening upward cycle (tidal bar or delta)

Unit 2

59 ft.

Consists of upward of laminated, small rippled sandstone with some transgressive mudstone

Unit 1

Tidal flat deposits forms the bottom of Lower Bahariya member and it is unconformably overlying the Khartia Formation
