Abstract
The goal of this paper is to clarify type, intensity and rate of movements, of topographically expressed features, by evaluation of surface and subsurface data through three cross sections in central part of Iraq. This was attained conveniently by comparing the selected contacts, within neotectonic time, with their original heights represented by global sea level heights and with contemporary topography. The chosen sea levels are assumed to be the original position of the undisturbed contacts. The present study assumed that any departure from the unique sea level could be caused by vertical movement (uplift or subsidence). Four topographically expressed features are included within three cross sections, each of them has specific stratigraphic boundary and unique sea level. These are: topographically expressed fetures of Samarra and Salahaldeen structures beside Shari and Tharthar Lakes. In addition, the sections includes: contemporary topography and the contacts of ; Middle/Late Miocene, Late Miocene/ Pliocene and Pliocene/Pleistocene, derived from geophysical depth maps with their associated global sea level. The first contact represents phase of tectonic stability but the other two are not , they are involved in this study to clarify and to be more close to the neotectoic events.
