The Geology of the Lyndonville Area, Vermont

This resource is available as a downloadable pdf file, a Web Map Service, and as an ESRI Service. The resource includes a Bedrock map, Tectonic map, Cross Section image, Generalized map, and a text on the Bedrock geology of the Lyndonville Area, Vermont. Abstract: The Lyndonville quadrangle is situated in northeastern Vermont, between the Green Mountain anticlinorium and the New Hampshire plutonic belt. Two sedimentary formations crop out within the quadrangle, the Waits River formation (Barton River member) and the Gile Mountain formation. Both belong to the St. Francis group which extends from Quebec into Massachusetts and which is here tentatively assigned Devonian age. The rocks consist of an alternation of graywackes, quartzites, siliceous limestones and volcanics, in which are emplaced a number of cross-cutting "granite" plutons.
