摘要
该研究的目的是确定伊拉克南部沙漠最近形态构造过程的类型和性质,并根据地质结构确定证实这些过程的证据。除了使用Arc GIS 10.2的卫星图像外,还使用地形图绘制了流域、河网、断层和褶皱,以及河流排水模式的纵断面和形式。查明了河流捕获或河流海盗活动的地点和分为两部分的河流流域的地点。还确定了线性方向的地质特征、高原的形成形式、交叉点、地面登陆、洪水沉积物和河流分叉。该地区的地质也被用来探测最近形态构造活动的发生。在这项研究中,我们发现Wadi Abu Ghar盆地的上游被Sadir和Abu Ghuwair盆地捕获。Sadir和Abu Ghuwair盆地在第四纪初期并不存在,这些盆地是在出现东北-西南走向的断层时形成的。最近的研究表明,下河谷的主要河流形成于第四纪早期。所有的地质和地貌证据都证实,该地区在第四纪发生了最近的新构造运动。
Recent Morphotectonics Processes in Lower Valleys of Southern Desert, Iraq
The aim of the study is to identify the type and nature of recent Morphotectonic processes Southern Desert of Iraq, as well as to identify the evidence that confirms these processes, depending on the geological structures. The rivers basins, river networks, faults and folds, as well as longitudinal sections and forms of river drainage patterns, which have been drawn by using topographic maps, in addition to satellite image by using Arc GIS 10.2. The location of the River Capture or River Piracy and the sites of the rivers basins, which were separated into two parts, were identified. Also geological features with linear direction, forms of formation of plateaus, intersection, ground landing, and flood sediment and river bifurcation were identified. The geology of the region was also used to detect the occurrence of recent Morphotectonic activities. In this study we find that the upstream of Wadi Abu Ghar basin, was captured by the Sadir and Abu Ghuwair basins. The Sadir and Abu Ghuwair basins were not present at the beginning of the Quaternary period, and these basins were created when a fault occurred with northeast-southwest trend. Most recent studies indicate that the main river streams of the lower valleys were formed during the early Quaternary period. All geological and geomorphological evidences confirm that Recent Neotectonic movements were happened in this part during the Quaternary period.
