Cardigan Pluton
The Cardigan Pluton is the most voluminous pluton in the state of New Hampshire, USA. The onset of magmatism was during the Acadian orogeny, and the pluton is part of the Kinsman suite of the New Hampshire Plutonic Series.〔 Allen, T., (2001) Nappes, Gneiss Domes and Plutonic Sheets of West-Central New Hampshire in Timothy W. Grover, Helen N. Mango, and Edward J. Hasenohr, editors, Guidebook to Field Trips in Vermont and Adjacent New Hampshire and New York, New England Intercollegiate Geologic Conference, 89th Annual Meeting. pp. A2.1 - A2.19.〕 The pluton is approximately 20 km wide by 90 km long and on average about 2.5 km thick. It is exposed in west-central New Hampshire along a north-northeast by south-southwest axis,〔(【引用サイトリンク】 title=Generalized Bedrock Geologic Map of New Hampshire )〕 extending from the town of Groton in the north to Dublin in the south. Mount Cardigan, from which the pluton is named, stands near the north end.
The pluton ranges in composition from granite to tonolite (s-type) and is likely derived from crustal melting of pelitic rocks. The rocks show foliation indicating they were implaced early in the Acadian Orogeny and subsequently overprinted by later metamorphic events. Minerals in the Cardigan Pluton include large K-feldspar megacrysts and quartz, plagioclase, muscovite, garnet, biotite, and less abundant minerals including sillimanite, cordierite, ilmenite, graphite, apatite, monazite, zircon, and allanite.〔Plank, T. (1987). Magmatic garnets from the cardigan pluton and the acadian thermal event in southwest new hampshire. American Mineralogist, 72(7-8), 681-688.〕 The pluton is dated at 411 +/- 19 Ma by the Rb/Sr method.〔 Lyons, J.B., Bothner, W., Moench, R., Thompson, J.B., (1997), Bedrock Geology of New Hampshire.
