Resource includes a Bedrock map, Tectonic map, and a text on the Bedrock geology of the Plainfield Quadrangle, Vermont. For more information see links provided. Abstract: Ordovician, Silurian and probable Devonian sedimentary rocks have been deformed metamorphosed and intruded by Devonian adamellite and granodiorite. The igneous and metamorphic rocks form part of the folded eastern limb of the Green Mountain anticlinoriurn which lies 13 to 20 miles to the west. Five mappable units in the quadrangle are from oldest to youngest, Missisquoi, Shaw Mountain, Northfleld, Waits River arid Gile Mountain formations. The Waits River and Gile Mountain formations have been repeated by the Brownington syncline which extends from the Memphremagog quadrangle southeastward through the Plainfield quadrangle. Other folds in the quadrangle include the Wood bury syncline and the Nichols anticline. These folds were developed during the early stage of regional deformation and metamorphism in east-central Vermont and trend strhparallel to the axis of the Green Mountain anticlinorium.
