I do not know if is Voltaire or another one, but the fractured rock Spirit is analyzing is pretty interesting...
First, there is a strange "extruded" portion, visible in the right/low region of this "crossed eyes" stereogram:  Herebelow, L257 PanCam image in the top portion; I highlighted in red the portion pictured with MI (lower mosaic):  Many interesting features, here. In addition to the sand filled fracture, there is a strange circular feature (enlarged in the small picture)... someone could see a biological fossil fingerprint in it ?...

It looks like a ventifact to me too. Is it a ventifact embedded in the matrix of the ignimbrite? Or is it a volcanic clast that was faceted by wind abrasion after the entire rock was exposed at the surface?
Or none of the above? |

My impression is the rock is an ignimbrite but the clast was faceted by the wind and then included into the rock perhaps by a second partial melting event. I don't know how this could happen pehaps as a result of more than one impact, one to move the wind abraded rock (basalt) to the vicinity of the ignimbrite the second to heat and merge the two?
