Home > Laskowski Ⅹ – April 6 > MS2026 Lemanskiite


Lemanskiite is a hydrous sodium calcium copper arsenate, and a member of the lavendulan group. Zubkova et al. (2017) found less water than in lavendulan and also monoclinic (pseudo-tetragonal) symmetry. Lemanskiite is thus a lower hydrate of lavendulan.

Lemanskiite here forms a 5 mm aggregate of blue plates to 0.8 mm. Also present are well-formed green lammerite crystals to 0.8 mm on the quartz matrix. From the collection of E.R. Laskowski (1949-2020), a mining engineer who retired to Tucson, Arizona.
