Opportunity Microscopic Imager mosaic, sol 3064: spherules A mosaic of four images captured with Opportunity's Microscopic Imager on sol 3064 (September 6, 2012) shows strange spherules embedded in a fine-grained matrix. At the time, Opportunity was on the inner rim of Endeavour crater at Cape York, exploring a fin-like outcrop.

Look like concretions. A number of the broken ones seem to have a resistant lump at or near the middle. Need a sample return mission.

Do we know the nature of the surrounding rock? Igneous? They don't look like vesicles formed from gas bubbles in lava. They seem too layered inside for that. Also I can not see any that merge or overlap (each spherule seems to have its own discrete boundary): wouldn't we expect that from gas-formed spherules?
