Sussexite

A slickenside in granular Franklin franklinite-willemite-zincite ore, coated with massive pinkish-lavender sussexite with a splintery, almost fibrous texture, grading into white fibrous sussexite. This is apparently the first find of sussexite from the Franklin and Sterling Hill area to combine white fibrous sussexite with pinkish massive sussexite. The massive sussexite, as shown by Dunn and Bostwick (1982), is intergrown with hodgkinsonite. This remarkable specimen was in John E. MacDonald’s collection, catalog no. JEM 1028, and bears an earlier marking, no. 44C, in black ink on white paint, but that collector is unknown. It is now no. ERV-442 in the collection of Earl Verbeek.  Photo SSX27b shows a side view of this same piece.
