Altough it's obviously a bit dangerous to re-interpret a photograph without revisiting the locality, I'm going to stick my neck out and suggest that the vertical fabric in the upper layer is in fact a form of cleavage, known as a fracture cleavage. I think that the original layers in this rock are clearly visible in the unfractured parts. This is therefore an example of the effects of a change in mechanical properties from layer to layer, and nothing at all to do with metamorphism. Mikenorton 19:42, 17 April 2008 (UTC)
- I visited this location last month on a trip to Death Valley and I can confirm that vertical fabric is a set of closely-spaced fractures that cut across the metamorphosed sedimentary layers. Mikenorton (talk) 16:15, 4 April 2020 (UTC)
