Preliminary crustal deformation model deduced from GPS and earthquakes’ data at Abu-Dabbab area, Eastern Desert, Egypt

Crustal deformation of the southeastern corner of Egypt derived from geodetic data

“…All Abu-Dabbab sites show inhomogeneous movement with different directions (rotational movement), and seem to be caused by the local seismic activity which characterized this area. The velocity rates of Abu-Dabbab sites is ranging from 1 to 4 mm/yr which is close to rates estimated by (Mohamed et al, 2013). Fig.…”

Morpho-tectonic Assessment of the Abu-Dabbab Area, Eastern Desert, Egypt: Insights from Remote Sensing and Geospatial Analysis

“…The granitic rocks of the Abu-Dabbab area were divided into two major rock types-older and younger Together with its economic importance, the Abu-Dabbab area has a long history of earthquakes that have attracted many researchers to investigate its seismic activity and earthquake swarms [28][29][30][31]. The source of the seismicity of the Abu-Dabbab area has been widely discussed based on the two contrasting opinions of tectonic and/or deep-root (mantle) origin [26,27]. Many researchers have proposed that the influence of regional tectonics is the main source of the high-degree tectonic activities for long periods in the Abu-Dabbab area [26,[32][33][34].…”

“…[44] classified the main tectonic elements in the Eastern Desert into three categories-(i) E-W trending fault systems, (ii) the Gulf of Suez trending fault systems, and (iii) the Gulf of Aqaba trending fault systems. Some researchers consider the Abu-Dabbab area a big, dome-like structure [27]. The study area is characterized by several elongated rock units, such as ophiolitic metagabbro and intrusive metagabbro to metadiorite, that are dissected by various fractures (Figure 2).…”

“…The Red Sea was formed as an ocean spreading center when the Arabian Plate diverged from the African Plate during the Early Miocene [25]. The study area represents part of the Red Sea Mountain Chain, which includes the backbone of rugged and high mountains that are parallel to the Red Sea coastline [26,27]. In this study, two major valleys (wadis, in local language) that drain into the Abu-Dabbab region have been examined-Wadi Abu-Dabbab and Wadi Mubarak (Figure 1).…”

“…In this study, two major valleys (wadis, in local language) that drain into the Abu-Dabbab region have been examined-Wadi Abu-Dabbab and Wadi Mubarak (Figure 1). Economically, the area was highlighted by the mining industry because it includes some gold mines in addition to many valuable minerals, such as feldspar, quartz, and phosphate [27].…”
