“…Instead, the inversion models were indicative for a fault acting as an impermeable barrier for cross-fault fluid transport. Clearly, the strike-slip configuration at this segment of the DST (Araba fault) is in stark contrast to the state of the fault at the DSB, where we observe very significant extensional forces which cause forking of the DST into two fault strands and formation of a very large pull-apart basin Garfunkel 1981).…”

“…At the DSB, and contrary to the Araba Fault, the DST has a very significant extensional component which causes splitting of the DST into two fault strands and the formation of a very large pull-apart basin Garfunkel 1981). Petrunin & Sobolev (2008) concluded from thermomechanic modelling studies that such a deep and relatively narrow pull-apart basin could only form in initially cold lithosphere if the major faults had low friction parameters of 0.1-0.2.…”

“…1a); the fault separates the Sinai plate in the west from the Arabian plate in the east with a total length of approximately 1000 km (Garfunkel 1981). As a consequence of continental breakup, the Red Sea and the Gulf of Suez were formed (Garfunkel 1981).…”

“…The DSB is delimited by fault scarps trending in north-south direction but the western fault scarp become weakly expressed at surface towards the northern Araba valley. The DSB is separated by the Al-Lisan Peninsula into northern and southern sub-basins (Garfunkel 1981;Ben-Avraham & Schubert 2006;Ben-Avraham et al 2008).…”

Crustal metamorphic fluid flux beneath the Dead Sea Basin: constraints from 2-D and 3-D magnetotelluric modelling

S U M M A R YWe report on a study to explore the deep electrical conductivity structure of the Dead Sea Basin (DSB) using magnetotelluric (MT) data collected along a transect across the DSB where the left lateral strike-slip Dead Sea transform (DST) fault splits into two fault strands forming one of the largest pull-apart basins of the world. A very pronounced feature of our 2-D inversion model is a deep, subvertical conductive zone beneath the DSB. The conductor extends through the entire crust and is sandwiched between highly resistive structures associated with Precambrian rocks of the basin flanks. The high electrical conductivity could be attributed to fluids released by dehydration of the uppermost mantle beneath the DSB, possibly in combination with fluids released by mid-to low-grade metamorphism in the lower crust and generation of hydrous minerals in the middle crust through retrograde metamorphism. Similar high conductivity zones associated with fluids have been reported from other large fault systems. The presence of fluids and hydrous minerals in the middle and lower crust could explain the required low friction coefficient of the DST along the eastern boundary of the DSB and the high subsidence rate of basin sediments. 3-D inversion models confirm the existence of a subvertical high conductivity structure underneath the DSB but its expression is far less pronounced. Instead, the 3-D inversion model suggests a deepening of the conductive DSB sediments off-profile towards the south, reaching a maximum depth of approximately 12 km, which is consistent with other geophysical observations. At shallower levels, the 3-D inversion model reveals salt diapirism as an upwelling of highly resistive structures, localized underneath the Al-Lisan Peninsula. The 3-D model furthermore contains an E-W elongated conductive structure to the northeast of the DSB. More MT data with better spatial coverage are required, however, to fully constrain the robustness of the above-mentioned off-profile features.

“…Figure 15 illustrates how the geometry of the fault system and the predicted plate motion (based on [11]) result in a general northward increase in both the rate of plate motion and the amount of convergence between Africa and Arabia. Hence, the northern DSFS could be viewed as an overall transpressional plate boundary (i.e., obliquely convergent), rather than the classical "leaky" transform [49].…”

The association of micro‐earthquake clusters with mapped faults in the Dead Sea basin

2014

About 1100 micro-earthquakes that occurred along the Dead Sea basin during the past 25 years express ongoing seismic activity along mostly obscured fault segments. We apply seismological and statistical methods in order to associate seismic activity with geological and geophysical data and to locate and characterize active fault segments in the basin; three regional 1-D velocity models and the double-difference method were used for the relocation of seismic events. Geostatistical analysis shows that in first order the micro-earthquakes reflect faulting along segments of the main longitudinal fault while seismic quiescence along historically active zones indicates locked segments and stress concentration. Based on waveform similarity, spatial and temporal proximity, we define earthquake clusters that comprise about 30% of the relocated seismicity and two thirds of the total seismic moment. About 80% of the clusters are associated with N-S trending faults. In two cases the clusters indicate a migration of the seismicity in time and space, one of which preceded the largest earthquake in our catalog (M5.2). In addition to the associated longitudinal activity, several clusters appear to represent faulting in east-west orientation which is interpreted here as a secondary fault system.
