Highalumina Basalt | Journal of Petrology | Oxford .

Abstract. Aphyric basalts of central Honsyū and the Izu Islands, Japan, are classified into three types: tholeiite with low A1 2 O 3 and alkalis, alkali basalt with variable A1 2 O 3 and higher alkalis, and highalumina basalt with higher A1 2 O 3 and intermediate alkalis. The tholeliite invariably yields normative quartz whereas the highalumina basalt may yield a little normative quartz or
