On this field trip we looked at plutons in three different tectonic domains in eastern New England: the Avalon Terrane of the Boston area, the Nashoba Terrane to the west, and the Merrimack-Central Main 'medial New England' Terrane to the west of that. These three regions have different stratigraphy, had different metamorphic histories, and experienced different varieties and episodes of igneous activity until they were finally assembled in the mid Paleozoic. The slightly ambitious itinerary permitted us to visit seven of the 11 scheduled stops. For details see the reference below.
