The close match of magnetic and gravity data with surface geology has led to the discovery of important regional features and now provides a way to map through the glacial cover.
This appears to have been due to a compressive force acting in a north- east to southwest direction.
The Merrimack province to the west in Connecticut and east-central Massa- chusetts is formed of a very thick west-dipping and west-topping sequence of pre- Silurian siltstone, graywacke, and shale.
