Plate tectonics does not exist on Ganymede.

I'm 100 km from the nearest library that might allow me access to Martin et al's paper. So I have no opinion on it.

But, you seem to think that the early assumption about icy volcanism mentioned by Kerr is a problem, having bolded it in your OP. You seem to agree that better imaging and data forced a reassessment of that idea, but then you ignore the reasoned explanation offered in the last two paragraphs of that article and instead refer to it as an example of "expansion tectonics".

You presume to read my mind? Reading through the thread, I noticed that at least on of the posters does not have access to Science. I'm working at home today, and I happen to subscribe to this journal, so that's where I went first. I notice that the article is not a peer-reviewed paper as you implied in several posts, and nothing in it supports your assertion, so I put together a post to summarize what Kerr actually reported without plagiarizing the whole thing. That took awhile. My purpose was to show how at least one of your links does not support your idea in any way. I may read the others eventually, but I have other chores to complete today. Understand?

Now, please tell us exactly how you think that article supports your idea, or withdraw the claim.
