Formula:
Na25Ba(Y,Gd,Dy)2(CO3)11(HCO3)4(SO4)2F2Cl
Colour:
Pale green to yellowish-green.
Name:
Named by A.P. Khomjakov, L.I. Polezhaeva, N.A. Yamnova, and D.Y. Pushcharovsky in 1992 honor of Dmitrii (Dmitry) Andreevich Mineev (Дмитрий Андреевич Минеев) (14 April 1935, Moscow, USSR - 5 August 1992, Moscow, Russia), Russian mineralogist and geochemist, and specialist in the field of geochemistry of rare earth elements at the Moscow Geological Prospecting Institute. He was a founder of the Russian Academy of Sciences and its first president. The suffix follows the Levinson rule for minerals with essential REE, denoting predominant yttrium.
