Geology and mineral genesis of Taba inland sabkha, southern Dead Sea Transform, SW Jordan
... The largest of these sabkhas is the Taba Sabkha, located about 35 km north of Aqaba (Fig. 1). It is about 50 km 2 in area, and consists essentially of clay, silt and evaporite deposits with minor aeolian sand horizons (Abed, 1998). ...
... The sabkha sediments are mainly the result of ephemeral deposition from these wadis. Twenty shallow pits (1-1.5 m deep) and 9 boreholes up to 17 m depth were drilled into the sabkha during detailed studies by Abed (1998). Samples and cores were obtained, and a few groundwater samples were collected during these earlier studies, which showed zonation in the sabkha reflected in both plant habitat and evaporite minerals as a function of increasing salinity of groundwater towards the centre. ...
... These massive mudstones occur at the distal part of the fan composing the centre of the sabkha (Fig. 14 A-C). Petrographic study (Abed, 1998) has shown that the detrital minerals include quartz, feldspar, chlorite, mica, kaolinite, illite, smectite and illite / smectite mixed layers. Calcite, though partly authigenic, is dominantly detrital and aeolian in origin. ...
The eastern rim of Wadi Araba in southwest Jordan displays distinct alluvial fans, which were developed since the time of formation of the Dead Sea Transform (DST), initiated in Mid Miocene times. The DST fault system controlled the development of the alluvial fans and their stacking pattern. Siliciclastic sediments were supplied from the east, and dispersed radially forming a stream-flow dominated alluvial fan system. The continuous uplift of the eastern granitic basement and overlying Phanerozoic sedimentary succession, and the active intramontane valleys, whose outlets at the mountain front were elevated continuously above the piedmont plains, resulted in deposition of alluvial fans that coalesced to produce a huge bajada complex comprising several generations of overlapping and superimposed lobes consisting mostly of granitic gravels. Eight lithofacies are identified, comprising three lithofacies associations: proximal fan; medial fan and distal fan. These were deposited in environments ranging from proximal shallow stream and sheet floods, channelized non-cohesive debris flows, medial heterolithic deposits, distal muds and sabkha evaporites.
هدفت الد ا رسة الحالية إلى استحداث نمط جديد من أنماط صناعة السياحة الحديثة، تحت مسمى
السياحة الجيومورفولوجية في منطقة وادي عربة؛ لما تحتويه المنطقة من تعدد كبير في أشكال
سطح الأرض، والتي تعد غاية في الروعة والجمال، واعتمدت الد ا رسة على منهجية استخدام
في تمثيل أشكال سطح الأرض في منطقة Digital Terrain Model-DEM النموذج العددي
الد ا رسة بأبعاد ثلاثية ورباعية؛ بهدف إظهار كافة مقومات سطح الأرض، والتي تعد عنص ا رً ممي ا زً
في تطوير نمط السياحة الجيمورفولوجية في المنطقة، حيث تم تطبيق تقنيات تحليل السطح
