In the northern part of the Bariya Depression (Western Desert, Egypt) the Eocene carbonate succession, unconformably overlying the Cretaceous deposits, consists of three main stratigraphic units
#0183;#32;The Bariya Depression is located near the central part of the Western Desert of Egypt where it shows elliptical geometry surrounded by a carbonate plateau mainly formed of Eocene rock units in its northern Eocene stratigraphy, especially of the Middle to Upper Eocene formations in the Bariya region has been a matter of dispute (Issawi et al., 2009).
#0183;#32;The Middle Eocene ironstone deposits of El Bariya Depression represent the only economic ooidal ironstone along the Tertiary paleoTethyan shorelines in northern Africa and southern Europe. These economic deposits represent the main exploitable iron ore deposits of
Bariya Oasis; they are the NESW, EW, and NWSE directed, the latter of which disturbs the younger formations (Middle Eocene) in the northern part of the Bariya depression (ELAKKAD amp; ISSAWI 1963).

The depression of the Bariya Oasis is an anticline of seas as an island. It was only during the middle Eocene time that the whole structure was submerged. The rocks of the middle Eocene Here one can see panoramic views of the angular unconformity between the Bariya Formation the overlying Eocene carbonates. In
In the northern part of the Bariya Depression (Western Desert, Egypt) the Eocene carbonate succession, unconformably overlying the Cretaceous deposits, consists of three main stratigraphic units; the Naqb, Qazzun and El Hamra formations. The Eocene carbonates are relevant as they locally host a large economic iron mineralization. This work revises the stratigraphic attribution of the Eocene
13 In the northern part of the Bariya Depression (Western Desert, Egypt) the 14 Eocene carbonate succession, unconformably overlying the Cretaceous deposits, 15 consists of three main stratigraphic units; the Naqb, Qazzun and El Hamra formations.
The Middle Eocene ironstones of the Bariya Depression consist of four iron ore types: manganiferous mudironstone, fossiliferous ironstone, stromatolitic ironstone and nummuliticooidaloncoidal
The Bariya Depression is located near the central part of the Western Desert of Egypt (Fig. 1) where it shows elliptical geometry surrounded by a carbonate plateau mainly formed of Eocene rock
OCCURRENCE OF BARITE MINERALIZATION IN Bariya depression, Western Desert of Egypt. The barite veins that trend in different directions are rocks are represented by the Naqb Formation which belongs to the Middle Eocene (Said, 1962) and comprises gray and pink limestone and by the Qalamoun Formation Bariya Oasis depression must first be studied.

#0183;#32;The Eocene strata in northern Bariya contain ironstone deposits of economic significance, some of them reaching a large size ().Despite significant research on these deposits (El Shazly, 1962, El Akkad and Issawi, 1963, Basta and Amer, 1969, and references therein), their origin is still a matter of recent publications show different and contrasting hypotheses for the

Ironstone deposits hosted in Eocene carbonates from Bariya (Egypt)New perspective on cherty ironstone occurrences. HighlightsWellexposed cherty ironstone is associated with Eocene carbonate in Bariya Eocene carbonates show extensive sealevel related diagenetic distribution was mainly controlled by postEocene major faults/ and Si
This paper gives new insight into the genesis of cherty ironstone deposits. The research was centered on wellexposed, unique cherty ironstone mineralization associated with Eocene carbonates from the northern part of the Bariya Depression (Egypt). The economically important ironstones occur in the Naqb Formation (Early Eocene), which is mainly formed of shallow marine carbonate deposits.
Bariya depression: Stratigraphic profile. Iron ore deposits/mines El Ghorabi, El Harra and El Gedida. Iron ores at Gebel Ghorabi, occurring mainly in lower Eocene limestone, include an oolitic type consisting essentially of goethite, a vesicular type containing hematite with pyrolusite and psilomelane, a hard, dark brown type consisting of goethite and hematite with some pyrolusite, and a
