A sabkha (Arabic: سبخة) is a predominately coastal, supratidal mudflat or sandflat in which evaporite-saline minerals accumulate as the result of semiarid to arid climate. Sabkhas are gradational between land and intertidal zone within restricted coastal …

Sabkha refers to low-relief flats that are formed by the accumulation of evaporite precipitation, often found in coastal desert or inland settings. These flats are characterized by wavy and crinkly laminae and are influenced by periodic wetting and desiccation of the surface. From: Encyclopedia of Geology, 2005

2023年8月5日 · Coastal Sabkha, an under-studied ecosystem in Qatar, has the potential to store blue carbon. In the present study, we investigated the carbon storage capacity of two Sabkhas from contrasting...

2004年10月12日 · This comparative study was conducted to characterize the coastal sabkha soils in Saudi Arabia. The results indicate that the engineering properties of coastal sabkha along the Red Sea different from those of the sabkha along the Arabian Gulf. The coastal sabkha along the Arabian Gulf is thicker and has more saline and sandier constituents.

2020年7月1日 · The depositional settings and growth habits of the buried halite offer insights into their origins and models for the interpretation of ancient evaporites. Coastal sabkhas (salt flats) form on the upper surface of coastal aquifers by evaporating groundwater in arid environments.

Sabkha is composed of sand deposits mixed with silt and clay intercalated with evaporites. Two types of sabkha are present in Saudi Arabia: the inland sabka, which is found in the northern part of the country and coastal sabkha, which is located along the Red Sea and Arabian Gulf.

2003年6月1日 · This paper describes the localities associated with (1) the mangrove swamps of the west side of the Al Dhabaiya peninsula; (2) the indurated cemented carbonate crusts, cyanobacterial flats and sabkha evaporites on the shore of the Khor al Bazam south of Qanatir Island; (3) the reef and oolitic sand flats on the coast just east of Jebel Dhana ...

2012年11月25日 · This paper presents a short review of the geomorphological and sedimentological characteristics of the Abu Dhabi Sabkha. The loss of coastal sabkha settings along the shoreline of Abu Dhabi Emirate is documented and the importance of preserving the last sections of pristine coastal sabkha is established.

2019年8月6日 · The high temperature, coupled with the aridity of the Abu Dhabi coast, explains the widespread occurrence of carbonates and evaporites in its coastal plain. Sabkha surface temperatures reach over 40 °C in the winter months, but …

The sabkha geomorphology offers evi-dence of spit formation, marine flooding, meteoric input in the landward zone and hints of aeolian deposition during shamal events. Gypsum precipitation is ubiquitous at the vadose zone and the phreatic zone in the upper and middle sabkha zone, and in the Dammam Formation underlying the middle and lower ...
