This meteorite display features a sample of a meteorite from the planet Mars! - a small sample of basaltic shergottite that was recovered from the remote Saharan desert near the Algerian-Moroccan border. This is the same strewnfield that has produced basaltic shergottite meteorites approved under several NWA numbers in the official Meteoritical Bulletin database, including NWA 2975, NWA 4880 and several others.
This Martian-origin meteorite was blasted off the surface of Mars millions of years ago. The source Martian bedrock was a deep basaltic magmatic rock. The impact ejection mechanism was so violent, that the resulting meteorites are highly shocked and contain pockets of melt glass and blackened glass veins.
Refer to the photo. The black centimeter cube is shown for scale and is not included. Your specimen will be a small fragment of this meteorite similar to the one shown in the photo. Each specimen is unique and will vary slightly in appearance. The display box measures approx. 3 inches by 4 inches (75mm by 100mm).
The meteorite specimen is encased in a clear acrylic gemjar which is placed inside a handsome display box that has a black pebblegrain finish and a glass viewing window. The Mars Rock can be removed from the case. The display has a color photo of the planet Mars in it, and would make the ideal gift for the science or astronomy geek. This would also make a fine outreach or educational prop and it would look great on display in the office or observatory.
