At first glance it looks like truncated cross-beds or an unconformity, which is consistent with the aeolian dune-playa setting. We've seen this at several places in Endurance and Victoria. But if you look closely at the lower beds, you can see a fabric of essentially horizontal beds, morte or less parallel to the upper beds. So I'm thinking that one or the other orientation of the lower bed may be an artifact of aeolian erosion. We need an up-close look. We'll also be able to tell more once Oppy starts taking images out of the flat (shadowed) light.
Of more interest is the open fracture in the upper beds. Is it a solution cavity, or what? Another example of the x-bedding is in 1P259578369EFF8900P2570L6M1. --Bill -------------------- |
