Thirty three benthic foraminiferal species belong to 23 genera and 16 families have been
recorded from the coral reefs of the Callovian Tuwaiq Formation, Khashm Al-Qaddiyah area, Central
Saudi Arabia. Three species: Astacolus qaddiyahensis, Nodosaria riyadhensis, Siderolites jurassica are
believed to be new. Nearly all identified foraminifera are of Atlantic-Miditeranean affinity. The foraminiferal
assemblage recorded in the present work is mixed of open marine, moderately deep marine

The Tineh Plain NW Sinai coast has been the subjected of several studies related to its stratigraphy, geoarchaeology, and sustainable development. Recently, the name of the Tineh Plain has emerged following the government of Egypt’s decision to establish a new economic project to develop the Suez Canal Sector (Suez Canal Corridor Mega Project). Landsat and SPOTsatellite images acquired for years 1984, 2000, 2006, 2008 and 2010 to detect temporal changes
coupled with field relations, verification, sampling, analyzing and photographing were conducted. Change detection of LU/

Bottom sediment samples were collected from
17 locations of the Dammam coast, Dammam city,
Saudi Arabia in April 2014. The concentrations of iron,
chromium, manganese, nickel, zinc, cadmium, lead, and
copper in the bottom sediments were measured by inductively
coupled plasma-mass spectrometer (ICP-MS).
The mean metal concentrations are Fe (372.4 μg/g), Mn
(5.9 μg g−1), Zn (5.1 μg g−1), Cu (6.3 μg g−1), Pb
(2.1 μg g−1), Ni (4.4 μg g−1), Cr (6.5 μg g−1), and
Cd (0.1 μg g−1). The distribution of benthic foraminifera

This article deals with the Upper Jurassic carbonates of the Jubaila Formation, exposed throughout the
Tuwaiq Mountains, Central Saudi Arabia and discusses the succession of palaeoenvironments resulting
from detailed field and lab work. Based on microfacies analysis and sedimentological data, twelve facies
are identified within the Upper Jurassic carbonates at Wadi Hanifa, Central Saudi Arabia. These facies are
attributed to six main facies belts. Within these facies and facies belts, four distinct biofacies assemblages
