Some magnetic and physical properties ( magnetic susceptibility , intensity of remanent magnetisation , ac current electrical conductivity and density ) of ١٨١ samples from ٣٠ sites of Middle Miocene basaltic rocks (β 1 N2) from Al- Kisweh region south of Damascus were studied, in order to extend the previous study ( Abou-Deeb, ١٩٩٧) to other regions so that these properties might be used as characteristic factors in discriminating the neighbouring basaltic flows .The measurement of the in situ magnetic susceptibility of ٧٥ basaltic sites , distributed on ٨ localities , in the region helped to calculate the mean value of the magnetic susceptibility of each locality and an overall mean value of the whole region, which might be used in any magnetic interpretation of the magnetic anomalies. Also, the density of ١٢٨ samples were measured and a mean value of the density of each locality and an overall mean density were calculated in order to be used in any future interpretation of any gravity anomaly in the region .
