N2 - Results of the investigation of caryopilite from goethite-neotocite-rhodochrosite ore of the Mazul manganese deposit, Krasnoyarsk Krai, Siberia, Russia. Caryopilite forms lamellar crystals; optical properties of mineral are following: Ng - yellow, Np - pale yellow, n m d 1.60, n g - n p d d 0.010-0.015. Chemical composition of the studied ñaryopilite corresponds to the empirical formula (Mn 1.95 Mg 1.61 Fe 0.63 2+ Al 0.58 9 0.23 ) 5.00 [(Si 3.88 Al 0.12 ) 4.00 O 10 ](OH) 6 , where 9 is vacancies. Concentration of Mg, unusually high for caryopilite, and high content of admixed Al allow to distinguish a new aluminium-magnesium variety of this mineral. It is formed under low temperatures as a result of the replacement of a primary, sedimentary neotocite. It is assumed that at temperature increase Al-Mg-rich caryopilite loses magnesium and aluminium which further concentrate in magnesian-manganese chlorite and spessartine.
