Abstract

After a short study of the geological conditions of formation of this subevaporitic basin, the sedimentary pattern and sedimentation processes are analyzed. In the eastern part of the basin, near the open sea, eolian sands are mixed with evaporitic and/or biochemical, mainly aragonitic, precipitations. In the western part occur abundant sheet-flood detritus while gypsum precipitates within an algal mat which develops both in the intertidal and in the infratidal zones. Thus, algal mats are not absolute bathymetric criteria especially in a saline or penesaline environment.
