density in primary carbonic inclusions, for the pressure (Bilal et Touret 2001,Bilal et Sheleh
2004).Using theses parameters the figure (6),show the obtained Results, which correspond to
about 1100-1300C for the temperature, 10-13 Kb for the pressure.
In conclusion it is suggested that the volcanic activity along the Syrian rift is due to the
presence under the Arabic plate of a mantle plume(Stein and Katz 1989,Stein and Hofman
1992 ,Stein et al 1993), active since Cretaceous times, locally refertilizing a residual (oceanic-
type) lithospheric mantle (Bilal and Touret 2001,Bilal and Sheleh 2004).

4. Tectono-seismicity characteristics
The tectono- seismicity characteristics are deducted from the satellite imagery, the field
survey, the seismic observatories data, the odometric measurements, and the analyzing of
ancient and recent earthquakes.
