Marion island is a fascinating place – I recently mentioned it in a blogpost myself. Less well know is it’s neighbour, Prince Edward Island.
I have something of an interest in South Atlantic & South-Indian ocean islands. Never had an oppurtunity to visit though, though I did contemplate moving to St Helena once. Most of those (all?) are hot-spot related – many with an accompanying trail of kimberlites and lamprophyres, and even carbonataites on the continent of Africa. I once was co-author on a conference poster on some of the volcanics associated with those hotspots:
New high-precision ages from the Gibeon and Maltahohe Kimberlite Fields, southern Namibia
Hoosen, Z. / Kurszlaukis, S. / Kiviets, G B. / Fourie, L F.
– appeared in the Journal of African Er=arth Science in 2000.
Thanks for the comment. I don’t think I ever ran into anyone who contemplated moving to St. Helena—quite an isolated place.
I should have encouraged readers to go to the high-resolution image of Marion Island. The 100 or so volcanic cones that dot the island are fascinating.
