The quantified phases included aragonite, calcite, dolomite, huntite, mono- and ortho-hydromagnesite, magnesian calcite, magnesite, monohydrocalcite, nesquehonite, spurrite
, and vaterite.
Associated minerals are: spurrite
, rustumite, hydrogrossular, andradite, calcite, magnetite and perovskite.
The olshanskyite occurs as pure, glassy-white, twinned microcrystals to 1 cm in length on spurrite
, and the nifontovite as rich, gray, glassy translucent masses with rare pockets of millimeter-sized crystals.
