The garnet-rich deposits discussed in this paper occur in northwestern Warren County, New York, and adjacent regions. The most important localities are shown on the accompanying geologic map. Garnets have been mined for abrasive purposes at a number of these places, but only the Barton Mine was active in 1937. The garnets of these localities are essentially the real almandite variety with some admixture of calcium and magnesium. Many of them have gem-stone color and translucency, but their highly fractured nature renders them largely unfit for jewelry.
