Guidebook To Field Trips In The Boston Area And Vicinity PDF Download

Excerpt from A Guidebook for Field Trips to the Boston Area and Vicinity: 68th Annual Meeting, New England Intercollegiate Geological Conference, October 8-10, 1976 Despite the location here of an unusual concentration of active geology departments as well as an office of the United States Geological Survey, the geology of southeastern New England, especially eastern Massachusetts, is less well understood than that of most other areas in New England. The sedimentary rocks of the area are only sparsely fossiliferous with the result that the stratigraphic chronology of the region is based on only a handful of fossil localities. The problem of interpretation is further compounded by a lack of stratigraphic continuity that makes it difficult to trace units. The region has been invaded by intrusive rocks in which many of the older units appear as discontinuous pendants and xenoliths; faults abound, cutting the region into slices and blocks of small lateral extent; and finally, glacial cover is wide spread, including moraines and extensive drumlin fields. Suspicion has grown over the last decade that some of the faults may be of great (although unknown) magnitude.
