Abstract The Aznam trough is a NW-trending, asymmetric graben on the northern Saudi Arabian coast of the Red Sea. Miocene or younger, high-Ti, tholeiitic basalts are exposed In the northern part of the trough. These (Aznam) basalts contain microphenocrysts of altered olivine, calcic plagioclase and clinopyroxene with subordinate amounts of ilmenite and orthopyroxene in a cryptocrystalline groundmass. A minor xenocryst/xenolith assemblage consists of quartz, sieve-textured plagioclase and a… CONTINUE READING
