The hot-spot derived Mt. Pleasant Caldera eruptions c.370-345Ma coincide with Romer's Gap. 66.235.38.214 (talk) 09:08, 25 October 2012 (UTC)[reply]

how could lithospheric thinning have been occurring, whilst the Arcadian orogeny was co-occurring, in the same regions, at the same time? Mountains were uplifted, due to continent:continent collisions, over a hotspot? 66.235.38.214 (talk) 09:23, 25 October 2012 (UTC)[reply]

Inexpertly, massive flood basalts are associated with RRR triple junctions, e.g. Ontong-Java plateau in the Pacific. Now, the Mt. Pleasant Caldera erupted, at the triple junction, between (clockwise) North America, Europe, and Gondwana. Is such significant? 66.235.38.214 (talk) 10:41, 25 October 2012 (UTC)[reply]

Location is incorrect[edit]

The lat/long coordinates for the Mount Pleasant Caldera are incorrect. The centre of the caldera is approximately 45.5N/66.755W, and the Mount Pleasant mine site is at 45.424155N/66.818942W. The caldera complex is due south from Frederiction, New Brunswick, not west as indicated on the current page. The picture at https://en.wikipedia.org/wiki/Caldera#/media/File:Mount_Pleasant_Caldera.jpg is also incorrectly located and is not of the Mount Pleasant Caldera complex, but an unrelated pluton that extends to the border with Maine. This information can be confirmed by matching up features with the geology map of New Brunswick: http://www2.gnb.ca/content/dam/gnb/Departments/en/pdf/Minerals-Minerales/2007-18_c.pdf — Preceding unsigned comment added by 156.34.186.131 (talk) 10:55, 3 August 2015 (UTC)[reply]

I just updated the coordinates. You are absolutely right about that image being incorrectly located so I removed it from the Caldera article and nominated it for deletion. Volcanoguy 09:54, 4 August 2015 (UTC)[reply]

Well, I am too busy adding links to articles and creating articles to help the Geological Survey of Canada and the Volcanism of Canada Workgroup. It is hard enough with only you and me, but that is because of lazy ass Canadians that do not know anything about Canadian volcanism till they get burnt and blown up into a million pieces.....A reactivation of the nearby Fundy Basin would likely engulf much of the Bay of Fundy with volcanism.....
