On White Island, New Zealand, the intensified period of strombolian-volcanian and phreatomagmatic explosive activity that commenced in March 1977 led to eruption of unusually primitive, high-Mg andesites. These are Fo 80-93 olivine-saturated rocks that have MgO contents up to 10% (Mg# = 65-71) and S...
