So if there is significant subsurface ice on Mars, does that mean that there could also much more subsurface granite than has been detected so far on the surface?
Here are the only references to martian granite I found: THEMIS detects blob of granite on Mars: http://themis.asu.edu/discoveries-granitepeaks Ruthorford and Hess, LPS 7 (1981) abstracts 915-917. "Granite genesis in a planetary context: processes and important variables for Mars." http://articles.adsabs.harvard.edu/cgi-bin...p;filetype=.pdf -Mike -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/

QUOTE (Juramike @ Jun 23 2008, 10:39 AM) THEMIS detects blob of granite on Mars: http://themis.asu.edu/discoveries-granitepeaks To be specific the THEMIS site notes "granite like" which includes an entire family of quartz-plagioclase-feldspar type rocks. They could very well be looking at diorite here, and as every good geologist will tell you......diorite should never be taken for granite. -------------------- If Occam had heard my theory, things would be very different now.

I looked at some of the older images. I think there is already evidence of ice subliming away in the images from sols 20 and 21. The colour combination in following images is from slinted:
The chunk on the left is in shadow in both images, and seems to be shrinking. Other smaller pieces seem to disappear altogether. -------------------- Antti Kuosmanen
