 | | Optically, the mineral is biaxial positive with a 2V measured at 60 degrees and all indices of refraction exceeding 1.80; r < v, distinct; and the fibers are length slow with Z approximately equal to c. |
 | | Associated minerals on the holotype specimen are quartz, goethite, dickite, and cinnabar; other species reported from the locality include barite, calcite, calomel, eglestonite, fluorapatite, galena, livingstonite, mercury, metacinnabar, montroydite, perhamite, pyrite, siderite, stibiconite, stibnite, and terlinguaite. |
