    Description: The Munakataite occurs sparsely on a single thumbnail-sized specimen from Tiger as medium cyan-blue acicular crystals, averaging 0.5 mm in length, and possessing a silky to adamantine luster. The crystals occur intimately associated with altered crystals of Boleite and two generations of Leadhillite crystals. Other associates on the same specimen include a third generation of Leadhillite crystals, Quartz, Cerussite, Djurleite, Covellite, and a number of unidentified, or inadequately identified, species, including a bladed microscopic lead sulphate silicate, with small percentages of zinc and copper—possibly a copper-bearing Queitite. The identification was made on the basis of compositional analysis using energy-dispersive X-ray spectroscopy (EDS), augmented with semi-quantitative wavelength-dispersive X-ray spectroscopy (WDS) for sulfur, and because the sample is consistent with the form and appearance of the species as set forth in the published description of Munakataite in 2008.
