Colemanite after Inyoite


Colemanite here replaced a large inyoite crystal 4.3 cm across. These pseudomorphs seem to form by encrustation as inyoite dissolves and colemanite precipitates. A hint of tan coloration comes from microscopic inclusions of todorokite. Part of the Charles Trantham (1936-2020) estate.
