Although it appears to be about mineralogists vs geomorphologists all over again, this time there is abundant evidence that the geomorphologically interesting site of Gale also includes interesting mineralogy.

Although it appears to be about mineralogists vs geomorphologists all over again, this time there is abundant evidence that the geomorphologically interesting site of Gale also includes interesting mineralogy. All four sites have abundantly interesting mineralogy. I believe the difference is that with Mawrth, it was more obvious that the clays, etc. were formed in place. The concern I read about the other sites was that the minerals may have been carried in and may not represent substantial deposits. However, I'm not a geologist! So these thoughts really should be read as a question. Any geologists care to comment on whether this is actually a concern? However, my real reason for favoring Mawrth was that it was the oldest of the sites, and sites like it may be the only records of the earliest processes on a world with a (then) significant atmosphere and available water. The world's experts on these issues also knew this, and went with a different site, so this was not a compelling argument. So Gale it apparently will be. -------------------- |
