Another Weird Shiny Thing on Mars

[The Curiosity Mars rover has imaged a small metallic-looking protuberance on a rock. Visible (in the image below the green lines point to it), the protuberance appears to have a high albedo and even projects a shadow on the rock below.
The image was taken with the right Mastcam on Curiosity on Sol 173 — January 30, 2013 here on Earth – (see the original raw image here), and was pointed out to us by Elisabetta Bonora, an image editing enthusiast from Italy. See a close-up of the object below.
As Bonora pointed out, the protuberance seems different than the rock on which it sits – it could be composed of material more resistant to erosion than the rest and similar material could be within the rock, or it could be something that is [grown] on the rock. However, it looks fairly smooth, and in fact it is not covered by dust as is the case for metal surfaces that tend to clean easily]. – UniverseToday.com
