TitleBrown calcite (ferrocalcite) from near Luning, Nevada
DescriptionThis sample of calcite is brown because it has a high iron content. Some of the iron is undoubtably replacing calcium in the calcite. Most, however, is present as desseminated hematite that is too fine grained to see. The sample is 9 cm in longest dimension.
