Abstract
Abstract
This issue of New Mineral Names provides a summary of several new species in the tetrahedrite-group along with examples of how museums are sharing type and cotype specimens. Currently there are approximately 50 sulfosalt mineral species in the tetrahedrite-group that have the general formula M2(A6)M1(B4C2)X3(D4)S1(Y12)S2(Z), with A = Cu+, Ag+, ☐; B = Cu+, Ag+; C = Zn2+, Fe2+, Hg2+, Cd2+, Mn2+, Ni2+, Cu2+, Cu+, Fe3+; D = Sb3+, As3+, Bi3+, Te4+; Y = S2–, Se2–; Z = S2–, Se2–, ☐. All members if the tetrahedrite-group are isometric and have potential applications high efficiency thermoelectric materials. Some the type specimens of tetrahedrite, and others in this review, are shared between museums. Having newly described minerals housed at multiple museums provides easier access to specimens for researchers around the world and serves to preserve these minerals in case of loss at any one the institutions. Here we look at the descriptions of stibiogoldfieldite, graulichite-(La), tennantite-(Cu), wildcatite, ellinaite, paqueite, burnettite, saccoite, and gurzhiite.
