Description:
The landward part of the 7 km wide sabkha at Umm Said, SE Qatar, is filled with a stagnant brine virtually saturated with halite. Recent dolomite occurs in the sabkha sediments, the quantity being fully accounted for by the amount of Mg++ ions lost from the interstitial brine.
The existence of a reflux system in the seaward parts of the sabkha was established. It was not, however, possible to gi ve any unequivocal demonstration of the effect of this potential system for dolomitization . Although both a reflux mechanism and Recent dolomite formation occur in this tidal flat, the first process has apparently not influenced the second sufficiently to permit the demonstration of reflux dolomitization.
