IMA 15-K: Thérèsemagnanite (redefined) and cobaltogordaite (discredited) Proposal 15-K is accepted, and thérèsemagnanite is redefined as a mineral of the gordaite group, with formula NaCo4(SO4)(OH)6Cl·6H2O. Cobaltogordaite, a new mineral species recently defined by Kasatkin et al. (2014) (IMA 2014043; see CNMNC Newsletter 22) and identical to thérèsemagnanite, is discredited. All data given in proposal IMA 2014-043 now correspond to thérèsemagnanite. The neotype specimen is deposited in the Fersman Mineralogical Museum of the Russian Academy of Sciences, Moscow, Russia, registration number 4561/1 - CNMNC Newsletter No. 27, October 2015, page 1230; Mineralogical Magazine, 79, 1229–1236.
