    Abstract: Twenty-seven basaltic fresh rock samples collected from North West Jordan at Ash-Shuna Ash-Shamaliyya area studied. The Ash-Shuna Ash-Shamaliyya basalt (SHB) introduced within Pliocene to Quaternary (recent) volcanism in North West Jordan, and produced within intraplate continental alkali to calc-alkaline basalt. The mineralogy analyses of the SHB ... Show More
