This is a thin section of dunite, a rock made up almost entirely of the mineral olivine, as seen in cross-polarized light through a Leica Z6 APO Macroscope. There is a band of black mineral grains to the left of center of the image that is a cumulate layer of the mineral chromite - in the magma chamber from which these minerals crystallized that band of chromite would have originally settled out in a horizontal layer. The width of the entire field of view visible here is just under 2 cm.
Unlike most of my GigaPans I didn't have help from the robot on this one. The thin section was moved by hand and the images were shot one by one. In fact, the stitch took far less time than the capture. Nonetheless it was well worth the effort - and the kind of task that is ideally suited to undergraduate/graduate students! :-)

There aren't any more yet, but I can and will make more when I get a chance. They're a little more effort intensive than a standard GigaPan because they don't utilize the robot. Nonetheless, I've got the equipment to make lots more of these - the biggest limitation right now is my time. Posted by rschott |

Great picture. Why don't you take this language from the "about this panorama" section... "There is a band of black mineral grains to the left of center of the image that is a cumulate layer of the mineral chromite - in the magma chamber from which these minerals crystallized that band of chromite would have originally settled out in a horizontal layer" and recreate it as a snapshot w/comment? That way you reduce uncertainty (by the person viewing the image) as to the information you convey - and you make fuller use of the Gigapan features. And if you REALLY want to make it educational, add a link in the snapshot comment to a web page that describes the crystallization process in greater detail & pictures. Great work, all in all.
