      <image:caption>Porphyritic olivine (PO) - PO spherules are dominated by olivines within glass and can contain "relict" crystals which are unmelted minerals. They tend to be more vesicular if the crystals are very small, and can have various textures.</image:caption>

      <image:caption>MET I-type - metal-bead bearing spherules have iron-oxide shells dominated by wustite. They can be homogeneous (no observable crystal boundaries) or dendritic (composed of Christmas-tree patterned crystals). The often have evidence of metal beads on their surface such as pits and thick magnetite rims.</image:caption>

      <image:caption>OXMET (transitional) I-type - spherules which share textural and mineralogical features of both MET and OX spherules. They commonly have wustite mantles (WUSM) surrounded metal beads which could be weathered into ferrihydrite (FER, an oxyhydroxide mineral), and magnetite rimes (MAGR).</image:caption>
