نظريات نشوء أهوار العراق : دراسة جيومورفولوجية

الملخص EN

The study aimed to detect how the emergence of the marshes of Iraq, and that by drawing a series of events tectonic successive during antiquity and later resulted from geological formations, and the type of paleoclimate accompanied the inception stages of the alluvial plain, which occupies the marshes large part to show how Anaxas on properties nature of the surface of the water and the region.

The purpose of the presentation of those facts above is to build an information base to form the point of view from which to mature evaluation of theories and opinions of many different disciplines, which interpreted the genesis of the marsh.

The research shows that the region suffered from the end of the third geological time (Miocene) until the early time four-wheel (Pleistocene) to large tectonic movements led to the Zagros and Taurus Mountains are torsional.

As a result of these movements southern sections landed twisting concave Vkont basin tectonic enormous size included the central and southern regions of Iraq was called (sedimentary easy).

As it turns out that most of the geological formations the plain sedimentary-era quartet of modern sediments river, marine, wind, Tboukaria, while triple-time configurations appear for a period (Miocene-Albulallosan) open on the outskirts of the aspects Alantqh neighboring alluvial plain, has been influenced by easy operations tyranny and the decline of several sea water times, and formed the rocks at the bottom of the sea and beyond have been affected by several external Giomorvih processes and tectonic movements on successive periods affected the surface area and the quality of the rocks and distribution The ancient climate in the region have been subjected to pulse periods of glacial honeycomb and rainy and dry affected Djiomorvih operations and the reality of geological formations, either the surface is level shrouded Tdhars simple confined him marshes permanent and seasonal, and the main sources of water for the marshes is the Tigris and Euphrates eastern tributaries and affected in the marshes in terms of supplying water and change riverbeds in several phases.

The research found that the views put forward by researchers to explain the genesis of the marshes focused on six reasons, researcher finds it difficult to return the marshes are to one reason, and it seems that it was formed because of several factors involved varying proportions in composition, and it was the biggest role of global activation tectonic and irregular distribution of sediment.

The date of the existence of prehistoric times, the roles of slaves and civilization Warka and Jmdh victory or leading up to it.
