Original locality for Merumite. Merumite [Am. Mineral., 34, 339(1949)] was shown by Milton, et al. (1967) to consist of fine-grained intergrowths predominantly of eskolaite (Cr2O3), quartz, and occasionally with 4 new minerals. Most tested specimens of merumite are virtually all eskolaite (Tony Nikischer, 2012, personal communication). Merumite occurs as black rounded grains in alluvial gravels of the drainage basin of the Merume River, Guyana.
