Geological Survey of Gulf of Aqaba - NEOM

This project (RFP no. 100244-SO-053) was successfully completed and handed over to NEOM within a tight timeframe of three months. It is situated along the northwestern part of Saudi Arabia (a corridor 80 km long by 1 km wide) along the eastern coast of the Gulf of Aqaba, opposite to Egypt’s Sinai Peninsula (Fig. 1). The study area is located in the Midyan Peninsula which is a complicated geomorphological terrain in terms of its geology, topography, and slope instability. Apart from the plains to the east and south, the northern parts of the project area are dominated by rugged mountains that range in altitude from 50 to 600 m above sea level. Mountain ridges are dissected by broad and narrow dry desert streams (wadis) that are largely inaccessible in the north of Magna but are easily accessible to the south of it.

The main objective of this study is to conduct a detailed geological survey and mapping of a corridor of area located to the east of the shoreline (up to 1 km to the east from the shoreline) along the eastern coast of the Gulf of Aqaba to assess the prevailing geologic conditions at the proposed assets’ locations, and accordingly to evaluate their effect on the design of the assets

The project was implemented based on the following tasks:

  • Desk study which included reviewing published geological maps, literatures and reports of the study area, in addition to preparing the base maps to be used in the site visits.
  • Conducting a geological walkover survey along the project area to:
    • identify the lithologic units and their most significant features
    • delineate the lithologic boundaries and the rock-soil boundaries
    • identify the lithostratigraphic succession at each site, and to
    • delineate the structural framework of the project area and the geological structures at each site, such as faults, major fractures and joints, shear zones, and dykes.
  • Produce a regional geological map of the project area at a scale of 1:100,000, which represents a corridor of about 1 km east of the shoreline widened in some places to include sites located further away.
  • Produce a series of local geologic maps at a scale 1:10,000 of the assets’ locations.
  • Providing an initial assessment of the potential slope instability (Geological Risk Assessment Report - Submitted and accepted).
  • Providing an initial assessment of the potential geohazards (Geological Risk Assessment Report - Submitted and accepted)
