Fe-rich globules on surfaces and in vesicles of AH glass. (a) SEM image of hundreds of Fe-rich globules on the outer surface of AH glass. Some globules are FeO and others are iron silicides. Note that globules occur only on original surfaces and not on broken ones (upper left and upper right). Gold arrow points to closeup of same region. (b) SEM close-up of globules. Some are round, but most are irregularly shaped. All are flattened, convex globules embedded on the surface of AH glass. (c) Multi-element SEM-EDS map of same area of (b) showing the distribution of multiple elements (see the color legend at bottom left). Fe-rich globules (red) on the AH glass matrix containing Ca and Si, with smaller amounts of Mg and/or Ni. All from level 457, sample E313, 413 cm depth.
