A New Mantle Xenolith Locality in Vermont

Basic Information
Author: McHone, J.G.
Description:A project to study deep-level xenoliths from northern New England mafic dikes. Vermont has several "breccia dikes" on the Shelburne Peninsula that are almost completely comprised of Champlain Valley-type rocks. At the North Hartland flood-control dam had many blocks of red-brown dike material that had pebble-to-cobble size inclusions of rock quite unlike any bedrock exposures in the area. A quick search revealed the parent dike in the spillway below the dam. Field report presented in the Vermont Geological Society quarterly newsletter - Green Mountain Geologist, Winter 1983. Volume 9, Number 4, page 78 of 84 in PDF.
