Kaznakhtite, ideally Ni6Co3+2(CO3)(OH)164H2O, is a new member of the hydrotalcite group within the hydrotalcite supergroup. The mineral was discovered at the Kaznakhtinskiy ultrabasic massif, Altai Republic, SW Siberia, Russia. It occurs as powdery aggregates forming flattened lenses up to 1.5 × 0.5 cm2 and veinlets up to 1 cm long and up to 1 mm thick in aggregates of chrysotile, lizardite, stichtite and dolomite. Other associated minerals include brucite, chromite, heazlewoodite, manganochromite, magnetite, and magnesioferrite. Kaznakhtite aggregates are composed of tiny platy grains up to 0.01 mm across. Kaznakhtite is light green, translucent in aggregates. It has earthy lustre and white streak. Cleavage is micaceous on {001}. Dcalc = 2.864 g cm-3. The mineral is optically uniaxial (V) with ϵ = 1.657(3) and ω = 1.676(3), weakly pleochroic in greenish hues, ω > ϵ. Chemical composition (wt.%, electron microprobe, Co valence state determined by XANES spectroscopy, CO2 and H2O calculated by stoichiometry) is: MgO 2.15, NiO 47.40, ZnO 0.22, Al2O3 0.16, Cr2O3 0.98, Co2O3 17.42, Cl 0.63, CO2 5.05, H2O 24.60, VO=Cl V014, total 98.47. The empirical formula calculated based on the sum of all metal cations = 8 apfu is (Ni5.54Mg0.47Zn0.02)£U6.03(Co3+1.83Cr0.11Al0.03)£U1.97C1.00O2.99(OH)15.84Cl0.16iP4H2O. IR spectroscopy confirmed the presence of CO32iV anions, OHiV groups and H2O molecules. The crystal structure was refined by the Rietveld method with RB = 0.19%. Kaznakhtite is trigonal, space group R.3m, a = 3.0515 (3), c = 23.180 (3) A, V = 186.93 (4) A3 and Z = 3/8. The strongest lines of the powder X-ray diffraction pattern [d, A (I, %) (hkl)] are: 7.72 (100) (003); 3.863 (24) (006); 2.630 (4) (101); 2.576 (10) (012); 2.294 (6) (015); 1.950 (4) (018); 1.526 (4) (110); 1.497 (4) (113). Kaznakhtite is a Co3+ analogue of reevesite, Ni6Fe3+2(CO3)(OH)16P4H2O. The mineral is named after its type locality.
