MARS ROCK : Retro Martian Meteorite Display - Dhofar 019 Basaltic Shergottite

This meteorite display features a sample of a meteorite from the planet Mars! - a small sample of the Martian shegottite "Dhofar 019" which was recovered from the remote deserts of Oman in January of 2000.

Refer to the photo. The black centimeter cube is shown for scale and is not included.


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 and handled or examined. The color artwork inside the display has a retro-vintage astronomy theme. This display would make the ideal gift for someone who has everything. This would also make a fine outreach or educational prop and it would look great on display in the office or observatory.

Martian basalt (shergottite)

A brownish gray stone weighing 1056 g was found in the desert. Mineralogy and classification (M. Nazarov and M. Ivanova, Vernad; L. A. Taylor, UTenn): fusion crust absent; meteorite is a doleritic rock consisting of subhedral grains (0.2–0.5 mm) of pigeonite (Wo9–1 5 En40–70, Fe/Mn = 20–40 at), augite (Wo30–40 En40–55), olivine (Fo25–60, Fe/Mn = 50–60 at), and feldspar (An36–68) converted to maskelynite; olivine has higher Fe/Mg than that of coexisting pyroxenes, as it is in nakhlites; mineral modes (approximate volume percent) are pyroxene = 65, maskelynite = 25, and olivine = 10, with accessory silica, K-rich feldspar, whitlockite, chlorapatite, chromite, ilmenite, titanomagnetite, magnetite, and pyrrhotite; secondary phases are calcite, gypsum, smectite, celestite, and Fe hydroxides; shock features include fracturing and mosaicism, maskelynite, and rare impact-melt pockets; extensive terrestrial weathering present mainly as carbonate veins crosscutting the meteorite, however, there are smectite–calcite–gypsum "orangettes" replacing maskelynite, which are similar to those in Allan Hills 84001and could be of martian origin; bulk chemistry close to Shergotty, with light rare earth elements strongly depleted. Specimens: type specimens, 113, 4, and 2 g, and two thin sections, Vernad; main mass with anonymous finder.
