There is certainly some soft sediment deformation and injection like structures in some of the other blocks - but as you say, without context it is difficult to work out what is going on Thanks for the comment John.

Interesting problem. From the pic the LHS looks like aeolian grainflow laminae. The slightly curved nature of the laminae and the wedging of the coarser bands suggests we are near the toe of the dune and it's a rather oblique cut The RHS as the appearence of a sabkha or damp sand flat with lenses of coarser sand in a wavy, dark silty matrix. The nature of the contact is clearly the challange, its either a fault (unlikely) or the edge of a soft sediment injection feature, which is my best guess. So I suggest that the stuff on the RHS is sabkha that has been remobilsed as an injectite. Knowing the context, relation to regional bedding etc would also help...
