A link to a good view of both the rocks with upper surface patterns as possible vesiculated erupted flow, or, an under a under-the-ice-cap flow of pressurized volatile holding material. This eruption of gas/liquid vesicles would form at the contact with an older, cold, and less pressurized solid or atmospheric contact. The vesicles will always be at the lower pressure contact surface, or at the contact along another material. Sometimes the bubble formation is just this deep, sometimes it can extend some depth, inches or feet, into a flow mass.
If another formation process was developing these spheroids along a surface, it would tell a part of the history as we are digging.

Notice the upper surface of a few of these rocks, with just the same depth of a single textural patterned surface. Can we turn a few of these and discover whether the vesicles are along both surfaces of a very thin flow or precipitation layer?

RA scoop with textured rocks. Sol 9, I believe.
