A SEDIMENTOLOGICAL STUDY OF THE PREGLACIAL PLEISTOCENE QI PALYNOZONE OF SDOM-2 BOREHOLE, SOUTHERN DEAD-SEA, ISRAEL

A sedimentological study using grain-size distribution analysis invest igated the processes of deposition that occurred during the preglacial Pleistocene age of the QI palynozone in the Sdom-2 borehole. The QI p alynozone of this borehole is found in a continuous very well sorted a nd coars-grained sand column. The lithological and textural characteri stics of this sand unit reflect processes of deposition that commonly prevail in environments of regional sand blankets. The sand was probab ly transported by aeolian processes and by braided stream river system s of the Bijou-Creek type.
