Extremely Pb-rich rock-forming silicates including a beryllian scapolite and associated minerals in a skarn from Langban, Varmland, Sweden

Abstract

We report preliminary petrographic and mineral chemical data for a rock hosting an unusual mineral assemblage from Långban, Värmland, Sweden. The rock is a two feldspar-scapolite-spessartine-romeite skarn. The bulk composition and high degree of enrichm
