Structural and sedimentological evolution of the Mesopotamian geosyncline (N.-Iraq)
Abstract
The type and the facies of the sediments are discussed in relation to the various kinds of tectonic movements.
A facies change from NW to SE in the Lower Jurassic indicates the existence of NE-SW trending basement blocks, along which horizontal and vertical movements took place.
Facies changes and the variation in thickness of the Gercus Formation (Eocene) observed in a number of structural units provides proof of synsedimentary folding.
A shift in the axis of the northern basin from a NW-SE trend in the SE part of Iraq to E-W strike in NW Iraq was apparently controlled by faults.
