Links to the original images?
Especially this one? I'd love a closer look. My apologies if the links were given in the earlier discussion, I missed it.
The flows from either side of the lava strips look interesting. Would they be some lava that spilled over and is a different colour than the strip, or mud flowing away as ice was melted by the lava, or something else?
And are the strips themselves a result or tectonic spread? What other mechanisms could produce that kind of feature?
