Home > Laskowski Ⅸ – October 7 > MS1968 Ekaterinite


Ekaterinite is a hydrous calcium borate chloride. The mineral is water soluble and absorbs water from the air. Malinko et al. (1980) named the species after Yekaterina Rozhkova (1898-1979), Russian mineralogist at the Institute of Mineral Resources in Moscow. This locality is an unusual iron deposit, which intruded into salt rock (Mazurov et al., 2018). Highly saline fluids precipitated unusual species, including four type species (to date). This same locality produces the banded seraphinite (species name clinochlore) readily available at online collectibles platforms.

Ekaterinite forms a white aggregate, 2 mm across, on a fragment of drill core. The matrix consists of crystalline anhydrite with calcite. From the collection of E.R. Laskowski (1949-2020), a mining engineer who retired to Tucson, Arizona.
