The spheres appear uniformly through the strata laid down. Volcanic or meteor sources would be more likely to appear in layers of spheres -- one layer of spheres per erruption or meteor impact.
Secondly, in this picture here [nasa.gov], you can see that some of the spheres have merged as they met. If it was volcanic, they would have melted together (and flowed together) rather than merely intersecting. To a geologist, the shape of the merged spheres has "molecular compound formed on-site" written all over it.

Kudos to the rover guys, NASA has failed to produse Martian news like this since before I was born.
