Vugs and Vacuoles in D’Orbigny Meteorite

D’Orbigny

The D’Orbigny angrite is famous for a lot of things. Among them are holes – vugs and vacuoles. The irregular vugs are usually filled with a tangle of well formed dark augite crystals. The vacuoles or vesicles are spherical. Most are empty. Some contain glass. These three dimensional features are hard to appreciate in two dimensional pictures. Trying to overcome this I’ve taken pictures from different angles then put them in motion as animated GIFs. The traditional Web View of Meteorite Times supports animated GIFs. The Magazine View does not.
