"Strange" in two ways:

1) There are a lot of little veinlets that run through the rock face, reminiscent of materials that are more resistant to erosion than the matrix in which they formed. In some places, the veinlets appear branched, even dendritic.

2) The whole rock face, at the MI scale, is shot through with tiny little spherical voids. A *very* few small spheres are visible still in the rock face, of about the same size as all the voids. Several of the remaining spheres are at the end of "stalks." like we saw in Pot of Gold and other rocks, both at Gusev and at Meridiani.

It looks like a form of concretion development, with veinlets sometimes feeding spheres and sometimes not, the whole thing encased in a more erodable matrix. A matrix that looks a lot like finely layered sediments (very, very fine layering is visible in the matrix, all along where it's eroded in corners).

I'm sure it's a product of erosion of a highly altered rock (maybe even lacustrine materials), but the whole thing has a very organic look to it.
