Theglassy type is formed almost entirely of a dark-brown glass with incipientcrystallization in black semi-opaque patches. There are no crystals ormicrolites present. The holocrystalline rocks are somewhat diabasic in structure, oftenophitic, with relatively little olivine, which is nearly completely changedinto serpentine. The feldspar is mainly labradorite much decomposed.The augite is nearly colourless, and is always allotriomorphic. Iron-ore isplentiful, apparently entirely ilmenite. These two types c
