Hi Craig,
Interesting seismic. An interpretation is a challenge, especially because I have no idea of the stratigraphy and the geological setting, but I shall give it a go:
What strikes me about the section in the bottom left corner is, that the beds in the center of the image have dropped down a lot.
This can be the case in a pull-apart situation in s strike-slip zone, or if the deeper formation is very mobile such as for example salt.
Also the top of the deep formation is very irregular. It reminds me of a section in a salt tectonics environment.
If that is correct, then the apparently isolated bodies in the middle of the other two pictures can be explained as salt structures. They look strange in insolation, but a section across a side of a salt “mushroom” can give you the isolated geometry as seen into first picture. The second picture could be part of a salt mushroom, but now intersected closer to the central part of the mushroom.
I would like to see deeper seismic, and I wonder if on deeper sections it would be possible to see velocity effects of the salt on a yet deeper formation. All of course assuming that the salt hypothesis is correct.
On the section at the top left, it seems that a section on the right hand side of the picture is “sagging”, this could be associated with salt withdrawal, which is supported by the congruent sagging of the deep (salt) formation. To the left of the down moving zone the beds seem to move up, which could be the result of salt flowing from the sagging area to the left were there is now more uprising of salt. Extreme uprising results in the formation of a diaper, such as I interpret on the bottom left image.
I would love to hear your final assessment.
