...U. Hålenius; F. Bosi Abstract Oxyplumboroméite, Pb 2 Sb 2 O 7 , is a new mineral of the roméite group of the pyrochlore supergroup (IMA 2013-042). It is found together with calcite and leucophoenicite in fissure fillings in tephroite skarn at the Harstigen mine, Värmland, Sweden. The mineral occurs...
