(
Springer Verlag
, 2015 , Article)
The Dohat Faishakh sabkha in Qatar is one of the rare modern environments where it is possible to study the formation of dolomite, a mineral whose origin has been long debated. In previous studies, dolomite formation in ...
Variability of blue carbon storage in arid evaporitic environment of two coastal Sabkhas or mudflats
(
Nature Research
, 2023 , Article)
Coastal Sabkhas are mudflats found in arid coastal regions that are located within the supratidal zone when high rates of evaporation lead to high salinity. While evaporitic minerals often accumulate underneath the surface, ...
