“…In terms of our figure of merit, sandstones with much lower permeability could still be effective storage targets. One additional factor that will be important, however, is how mineralization and dissolution will affect the fracture permeability (Sausse et al, 2001). …”

“…Therefore, characterization of the internal structure of exhumed fault zones is important for understanding their mechanical, hydraulic and seismic behaviour (Conti et al, 2001;Faulkner et al, 2003;Wibberley and Shimamoto, 2003). In particular, the analysis of deformation mechanisms and healing processes (cementation and compaction) provide information about temporal and spatial changes in the strength of faults (Sleep and Blanpied, 1992;Schulz and Evans, 1998;Janssen et al, 1998;Muchez and Sintubin, 1998;Lin et al, 2001;Sausse et al, 2001). …”

We compare fault-related deformation of three segments of the major transform plate boundary between Africa and the Arabian plate, the Dead Sea Transform (DST), namely: the Arava/Araba fault (Jordan/Israel), the Serghaya fault and the Ghab fault (both Syria). These segments show both similarities and marked differences in faulting deformation and fluid-rock interactions. In the case of the Arava fault, fault damage occurs across a zone up to 300 m wide. A fault core/gouge zone is not exhibited.Along the Serghaya fault, the typical fault zone architecture with a main gouge zone and a damage zone of up to 100 m thickness is exposed. Effects of faulting in the Ghab segment are shown by subsidiary faults and the formation of fault breccias. As in the Arava fault segment, a fault core is not exposed. were active along Serghaya fault and Ghab fault, where fault rock cementation led to * Corresponding author.

Such low permeability could create domains of higher pore fluid pressure, which reduce the effective shear stress required for slip on the fault. These differences in fluid-rock interactions may have played an important role with respect to the occurrence of earthquakes. We suggest that the recurrence interval on a fault segment that recovers after an earthquake without fluid assisted healing (e.g. Arava fault) should be longer than on segments with strong fluidassisted healing (cementation; e.g. Serghaya fault, Ghab fault), given that the regional stress field is the same.

The geochemistry of carbonate fault rocks has been examined in two areas of the Arava Fault segment, which forms the major branch of the Dead Sea Transform between the Dead Sea and the Gulf of Aquaba. The role of fluids in faulting deformation in the selected fault segment is remarkably different from observations at other major fault zones. Our data suggest reduced fluid rock interactions in both areas and limited fluid flow. The fault did not act as an important fluid conduit. There are no indications that hydrothermal reactions (cementation, dissolution) did change the strength and behavior of the fault zone, although the two areas show considerable differences with respect to fluid sources and fluid flow. In one area, the investigated calcite mineralization reveals an open fluid system with fluids originating from a variety of sources. Stable isotopes (d 13 C, d 18 O), strontium isotopes, and trace elements indicate both infiltration of descending (meteoric and/or sea water) and ascending hydrothermal fluids. In the other area, all geochemical data indicate only local (small scale) fluid redistribution. These fluids were derived from the adjacent limestones under nearly closed-system conditions.
