aphyric basalts in New Mexico, the alkaline basalt of Broken Tank (Chamberlin et al. 2002) and the subalkaline basalt of Chamisa Mesa (Chamberlin and McIntosh 2007), both display distinctive ophitic to subophitic textures. These very limited observations suggest an antipathy between aphyric ophitic basalts and oliv-ine phyric basalts.
