Mineralogy and the Texture of the Basalt in Hail Region, Saudi
The study is carried out to list mineralogy and texture of the basalt in Hail region. 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.

It can be a crucial part or architecture, creating pattern or rhythm and allowing the viewer to believe the piece moves through space. Textures create a different experience; they allow more than one sense to be used at once by just "seeing" it.
