Resorbed Apatite Crystal in Pitchstone Glass (IMAGE)
Caption
This is a false color electron-microscope image of a resorbed apatite crystal (green) in pitchstone glass (blue). The composition of the pitchstone glass and the characteristic mineral textures are identical in the studied pitchstone sites of the Sgùrr of Eigg and Òigh-sgeir, although over 30km apart, indicating a common origin, and thus a large and geographically widespread volcanic eruption.
