ID: 2862524
New London Gneiss

Age: Neoproterozoic (541 - 1000 Ma)

Stratigraphic Name: New London Gneiss

Description: New London consists of a layered facies and a massive facies. Layered facies described as alternating layers of light-colored biotite-quartz-plagioclase gneiss and amphibolite. Massive facies described as a granodiorite gneiss with a uniform texture, grain size, and color. Contains shiny black biotite plates and distinctive magnetite grains.
