کاملترین تعریف:

Specialty Definition: SABKHA

Geography:Dry, vegetation-free, flat area at the lowest part of an undrained desert basin, underlain by stratified clay, silt or sand, and commonly by soluble salts. Source: European Union.

Mining:A. A supratidal environment of sedimentation, formed under arid to semiarid conditions on restricted coastal plains just above normal high-tide level. It is gradational between the land surface and the intertidal environment. Sabkhas are characterized by evaporite-salt, tidal-flood, and eolian deposits, and are found on many modern coastlines, e.g., Persian Gulf, Gulf of California. See also:tidal fla b. Any flat area, coastal or interior, where, through deflation and evaporation, salts crystallize near or at the surface c. In the rock record, a sabkha facies may be indicated by evaporites, absence of fossils, thin flat-pebble conglomerates, stromatolitic laminae, desiccation features such as mud cracks, and diagenetic modifications, for example, disrupted bedding, dissolution and replacement phenomena, and dolomitization. The sabkha environment may have been significant in the formation of certain petroleum and sulfide-mineral deposits. Etymol:Arabic. Also spelled: sabkhah. Syn:sebkha e.g., Persian Gulf, Gulf of California. See also:tidal fla.

2.An environment of coastal sedimentation characterized by arid or semiarid conditions above the level of high tide and by the absence of vegetation. Evaporites, eolian deposits and tidal-flood deposits are common in sabkhas.
