The Geology of the Hardwick Area, Vermont

This resource is available as a downloadable file, ESRI Service, and as a Web Feature service. Resource includes a Bedrock map, Tectonic map, and a text on Bedrock geology in the Hardwick area, Vermont. Abstract: Metamorphosed Upper Cambrian, Ordovician, Silurian and probable Devonian sedimentary and intermediate to basic igneous rocks have been deformed in at least two stages and subsequently cut and locally metamorphosed by Devonian granodiorites. The principal stages of deformation seem related to the development of the Green Mountain anticlinorium and the Willoughby arch. Each of these large-scale structural features has related smaller scale linear and planar fabric elements. Criteria are given that are useful in assigning the small-scale fabric features to either the development of the Green Mountain anticlinorium or the formation of the Willoughby arch. Vertical movement appears to have played it conspicuous role in the formation of both the Green Mountain anticlinorium and the Willoughby arch.
