In this Space.com article Steve Squyres explains how the soil Spirit has churned up lately contains a large amount of sulfates.

One piece of the puzzle that wasn't answered back at Paso Robles is what form the sulfates take. Are they concentrated in small grains, or just a major consituitant of soil in general? We've seen lots of locations, especially back down on the West Spur, where it looked like there were small brittle pebbles being crushed under the wheels exposing the bright material. For the Paso Robles trench, they churned up so much material that it became a mix which then tested very high for magnisium sulfate.
If there are salt pebbles, they might just be transported from other locations up to the peak (via the 'short distance transport' mentioned recently by JPL in relation to the grain size of sands in the Cliffhanger drift trench). But as far as I know, where the sulfates were originally deposited is still a mystery. |
