The Dead Sea Fault System (DSFS) steps-over at the northern head of the Gulf of Aqaba (GOA), crossing the evolving continental shelf. We report detailed processing and interpretation of high resolution sub-bottom profiles of the north western tip of the GOA down to a depth of about 120 m. Our data reveal stepping seafloor morphology comprising a series of relict coastline features, primarily ...

Learn MoreThe basic principle of stratigraphy is the law of superposition of strata: in a normal sequence of rock strata, each stratum is older than the one above it. An exception to this rule is observed only when tectonic deformations have altered the original sequence of strata and caused strata to be inverted.
