This unusual suite of minerals occurs in Quincy granite (Mississippian or Devonian hypersolvus alkali granite) exposed in a road cut on Route 114, 200 yards west of its junction with Route 121.

Much of the danalite first reported from the locality is genthelvite (Miller and Cares 1986). Danalite is the Fe end-member, and genthelvite is the Zn end-member of the danalite-genthelvite series. It is probably best to label specimens that have not been chemically analyzed as danalite-genthelvite series.

Pennsylvanian - Devonian
298.9 - 419.2 Ma



ID: 2756765
alkali-feldspar granite of Cumberland

Age: Paleozoic (298.9 - 419.2 Ma)

Description: Gray to blue-gray. medium- to coarse-grained, equigranular to porphyritic alkali-feldspar granite (phenocrysts of perthite). Massive to locally foliated. Contains perthite, quartz, abundant accessory riebeckite and aegerine, and lesser astrophyllite, anegmatite, zircon, allanite, fluorite, and opaque minerals. Plagioclase is notably absent. Hypersolvus, strongly peralkaline granite. Includes rock mapped formerly as Rhode Island Quincy Granite.

Comments: Part of Esmond-Dedham Subterrane (West Bay Area). Per printed map: age of rock based on radiometric data from RI005. Original map source: Hermes, O.D., Gromet, L.P., Murray, D.P., and Hamidzada, N.A., 1994, Bedrock Geology of Rhode Island; s44gbr95, Geological Survey of Rhode Island, scale 1:100,000.
