Connecticut Quarries (excluding Granite)
List and Location of Individual Quarries

The following list is brief as the source book cited below is a book on the geology of Connecticut and does not list many specific quarries, although it did describe stone quarried in various areas of Connecticut. I have listed these areas when I could discern that actual quarrying operations had taken place. Other areas appear to only be places where samples of stone were described and may not have been quarried. While my major area of study is dimensional stone quarries, I have also listed quarries in which the stone was used as crushed stone as well.

Carbonate Rocks - Marble and Dolomitic Marble

"The metamorphic carbonate rocks are known as marbles, and consist either of crystalline calcite or dolomite, the first known simply as marble, the second as dolomitic marble. Commercially the name marble is extended to include any soft rock which takes a good polish, and hence may include not only limestones of various colors, but also serpentine.." The carbonate rocks in Connecticut range from pure white, often dolomitic, to dark gray marbles, which is due to the graphite.1

Stockbridge Tremolitic Marble, East Canaan, North Canaan, Connecticut

The Stockbridge marble is a dolomitic marble and lies "in several detached areas in the western part of the state. The two most important are the irregular belt extending across the northwest corner through North Canaan, Canaan, Salisbury, and Sharon, and the narrow belt lying mostly in New Milford and Danbury. This marble was first studied in Massachusetts, and was named after the town of Stockbridge in that state." The sample described in the Lithograph was a white dolomitic marble.

The rock has been quarried in Massachusetts and East Canaan, Connecticut. The East Canaan marble was used at the state capitol at Hartford, Connecticut, although the main use of the rock was in the manufacture of lime.2
