I did write a comment but wasn't registered to comment at the time, so it got lost. I mentioned the Dolomites in my 1982 article on Darwin and coral reefs. You can find this on Darwin Online http://bit.ly/fAEtFA.

The full ref is:<br /><br />Alistair William Sponsel, 2009. Coral reef formation and the sciences of earth, life and sea, c. 1770-1952. A dissertation presented<br />to the faculty pf Princeton University in candidacy of Doctor of Philosophy.<br /><br />I have a pdf copy from the author, but as it's unpublished, I don't feel I could to pass it on to a third party without his prior permission, especially as he has been writing it up as book. Not sure how far he's got with that, though. Best if you wrote to him direct, at Harvard. You can find him on their website.<br /><br />(FYI my own special interests are living and fossil corals and reefs, general and regional geology, biogeography, ecology and history of these subjects. http://bit.ly/ibtF62)carpediemhttps://www.blogger.com/profile/15196927280086479947noreply@blogger.comtag:blogger.com,1999:blog-6314190564205081026.post-35184880311429181942011-02-01T10:34:35.385-08:002011-02-01T10:34:35.385-08:00Is the mentioned ref.:

He and Charles Lyell developed and exchanged ideas about the mobility of the earth's crust, clearly envisaging the earth as a dynamic system. This led them also to speculate on mobility of the inner layers of the earth too.
