Abstract |
: |
Al Lith sabkha is one of the extensive sabkhas on the Red Sea
coast. This study investigatesit s sedimentologicacl haracteristicsin cluding the
sedimentarys tructures,s tratigraphy,a ndm ineralogy. It also ooverst he hydrochemistry
of both the groundwater and the pore water. The sabkha deposit is
mainly arenaceousc, omposedm ainly of sand with clay lenses. Carbonates
and evaporitesa re presente ither as cementingm aterial or as intergranularc rystals.
Mineralogically, they exist in the form of aragonite, dolomite, calcite,
gypsum, halite and/or anhydritem inerals. The percentageso f the carbonates
and evaporitesd ecreasef rom the sabkhac enter outwardsa nd also decrease
with depth.
The groundwater is mainly of moderately hypersaline and highly hypersaline.
Slightly hypersaline and very saline water also exist in the southern
section of the sabkha. The Total Dissolved Salts (mS) of the pore water decrease
with depth and generally follow the variations present in the salinity
maps..
When correlatedw ith salinity, the measuredio n concentrationse, xceptt hose
for Na+ and CI-, mark the four different typeso f the groundwater( very saline,
slightly hypersaline,m oderatelyh ypersalinea, ndh ighly hypersaline |
