The basalt flows belong to the Arabian Harrat volcanism. Cenozoic volcanism has produced 13, vast, basaltic fields in western Saudi Arabia, covering a total area of about 100,000 sq. km. The volcanism starts in the late Cretaceous time and continues periodically into the Holocene. The basaltic field presently investigated is known as Harrat Al-Hamad (or Harrat As-Shamah) which lies in northwestern Saudi Arabia, and continues northwards into Jordan. Mineralogical analysis of 20 rock samples indicates that the rocks are products of continental intra-plate magmatism;mostly as coarse-grained silica—under saturated olivine-rich alkali basalt. Mineralogical study shows that rocks are olivine, plagioclase, pyroxene, Nepheline and Opaque minerals. They correspond to alkali olivine basalts. Moreover, the main well-defined texture is intergranular, vesicular and amygdaloidal texture.展开更多

Therefore, the aim of the present study was to assess sources of knowledge about CPR and its association with demographical characteristics in Saudi Arabia. Methodology: Data about CPR were obtained from 440 Saudi volunteers living in the city of Hail, Northern Saudi Arabia. Results: Out of the 440 study subjects, 257/440 (58.4%) individuals were found to know about CPR. Out of 257 individuals, 154/257 (60%) were males and 103/257 (40%) were females. Conclusion: The level of awareness toward CPR in general population of Northern Saudi Arabia, which requires more efforts at community basis. The most effective source for raising awareness is the appropriate utility of social media, as well as, implementing sustainable program for delivering CPR training courses evolving all community settings.展开更多
