الملخص EN

Two wells were drilled in Khor Alzubair and Umm Qasir.

Five samples were selected from different depths for the purpose to conduct sedimentological and mineralogical analysis in the study area.

Results revealed that lithology of Hammar formation is silty clay, but the depth extent is different, with 2-18 meters in Um Qasir and 2-16 meters for the latter.

Mineralogical analysis showed that clay minerals from the first well in Khor Alzubair site are montmorillonite, chlorite, illite, palygorscite and kaolinite, whereas clay minerals analysis for the second well at Umm Qasir site are montmorillonite, kaolinite, chlorite, illite and palygorscite.

The existence of palygorscite considered as indication of marine environment with high degree of evaporation with mixed type of both fluvial and marine environments.
