BRADACZEKITE, NaCu4(AsO4)3, A NEW MINERAL SPECIES FROM THE TOLBACHIK VOLCANO, KAMCHATKA PENINSULA, RUSSIA
Bradaczekite, NaCu4(AsO4)3, was discovered in a fumarole in the North Breach of the Great fissure Tolbachik eruption (GFTE) in 1975–1976, Kamchatka Peninsula, Russia. Bradaczekite forms aggregates of dark blue plates elongate along [¯102]. The well-developed forms are {010}, {¯311}, {111} and {¯112}...
