The Cardigan Pluton was built during what Middle Devonian period?
Cardigan Pluton The Cardigan Pluton is the most voluminous pluton in the state of New Hampshire, United States. The onset of magmatism was during the Acadian orogeny, and the pluton is part of the Kinsman suite of the New Hampshire Plutonic Series. 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, 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.
Illinoian (stage) The Illinoian Stage is the name used by Quaternary geologists in North America to designate the period c.191,000 to c.130,000 years ago, during the middle Pleistocene, when sediments comprising the Illinoian Glacial Lobe were deposited. It precedes the Sangamonian stage and follows the Pre-Illinoian Stage in North America. The Illinoian Stage is defined as the period of geologic time during which the glacial tills and outwash, which comprise the bulk of the Glasford Formation, accumulated to create the Illinoian Glacial Lobe.
