English: Big garnet amphibolite from the Precambrian of New York State, USA. (public display, Geology Department, Wittenberg University, Springfield, Ohio, USA)

In the eastern Adirondacks of New York State, "big garnets" are famously known from the North Creek and Warrensburg areas (e.g., see Hollocher et al., 2008). This specimen consists of several large, red-colored, almandine garnet crystals in a dark-colored amphibolite matrix. Amphibolite is a metamorphic rock having hornblende amphibole and plagioclase feldspar.

Locality: Gore Mountain, Adirondack Mountains, Warren County, northern New York State, USA
