The Karun III Project is located on the simple folding zone of the Zagros Mountain Range. The thick sedimentary rocks of this area have created anticlinal & synclinal foldings, from the northeast to the southwest.
Keif Malek Anticline – with the length of 20 to 30^Km and the width of 1^Km , extending from the north-west to the south-east, consisting limestone in the Asmari Formation, with central layers of shale & marl stones in the Pabdeh Formation – is part of the structural geology of the Dam site. This folding passes through the Dam project, extending to the southeast and
Pol-e Shaloo location. In general, the structural geology of the location of the project consists of limestone, calcareous marl, and shale stone in Asmari & Pabdeh Formations.
