Ghubara-animation (10X)
Animation of 28 DSLR frames (reduced to 640x480 format). The images were made using cross-polarized light through a petrographic microscope. The lower polarizer was rotated 5 degrees between frames. Field of view is about 0.0003 inch, top to bottom.
The "Ghubara" meteorite is found on the surface of the desert in Ghubara, Jiddat Al Harasis, Oman. Since its discovery in 1954 about 5,000kg have been recovered. It is unusually rich in noble gases and is classified as a regolith breccia L5 meteorite with xenolithic (mixed) inclusions.
Thin section acquired from Mike Kagelmacher (Rock-Slides on eBay).
