A granite deposit/quarry located 6.1 km (3.8 miles) E of Branford, on private land. Originally operated by the Norcross Brothers Company. It opened in 1887 and still operating as of 2023, with operations gradually progressing northward. The current Stony Creek Quarry works the Neoproterozoic Stony Creek Granite, which is used for construction, monuments and aggregate.
"The Norcross Quarry, in the township of Branford, about 1 and 1/4 miles north of Stony Creek Village, is well worth a visit. A spur of the railroad runs near the railroad station at Stony Creek to the quarry. Along this spur are numerous large blocks of discarded quarry material. The operators discard the coarse and irregular portions and these are of particular interest in studying and collection specimens of minerals. Besides crystals of quartz, feldspar, and muscovite, specimens of magnetites, limonite, apatite, pyrite, zircon and occasionally calcite, epidote and zoisite may be obtained"
The pluton is bordered by the Plainfield Formation, which includes quartzite and calc-silicate units plus gneiss and amphibolite. An exposure of calc-silicate rock next to the granite contains salmon calcite, quartz, epidote, scapolite, grossular, fluorapatite, pyrite and opal-AN. All units are intruded by Permian Narragansett Pier Granite/pegmatite.
Workings include surface openings. There are 2 quarry sites. The older, lower quarry is 450 feet long N-S, 200 feet wide, and as much as 65 feet deep. The upper quarry is 100 feet N and is 500 feet long N-S, 100 feet wide, and as much as 40 feet deep.
Production data are found in: Dale, T.N. (1911).
Production information: Figures are lacking but production of good building stone was large.
Reserve-resources data: Figures are lacking but a large volume of rock remains.
Analysis results: SiO2: 72.73%, Al2O3 & FeO: 16.95%, CaO: 1.05%, MgO: trace, K2O: 8.15%, Na2O: 0.90%, loss 0.22%.
