The Merrimack belt of central Massachusetts overlaps the junction between two zones of Ordovician and older rocks, the Bronson Hill zone on the west and the Nashoba zone on the east, and consists of Upper Ordovician, Silurian, Lower Devonian, and local Pennsylvanian strata. Distinctive groups of these strata form six subbelts. These are, from west to east, the Ware, Gardner, Southbridge, and Wachusett Mountain subbelts, in the western and central parts of the belt, and the Nashua and Rockingham subbelts, in the eastern part. -from Authors
