Nanisivik Mine, Arctic Bay, Baffin Island, Nunavut, Pyrite and Sphalerite

The Nanisivik Mine, a significant zinc mine was, during its operating days, the second-most northerly base metals mine in the world. WAY up there! It has been closed for over a decade now and has the site has been rehabilitated so that little trace of the mine remains now.
The Nanisivik mine is famous for unusual pyrite crystals. Pyrite crystals often show combinations of the cube, octahedron, pyritohedron, dodecahedron and trapezohedron. In addition, many of the crystals are actually pseudomorphs after marcasite or oriented overgrowths of pyrite on pyrite pseudomorphs after marcasite! All of these factors result in VERY interesting pyrite crystals habits. Many of these specimens are very similar to the ones pictured in the Mineralogical Record Volume 21, Number six, Pages 515-534.
Besides the interesting pyrite crystals, very nice specimens of sphalerite (the ore mineral of zinc at the mine), quartz, dolomite and calcite were recovered during mining operations. Here are some excellent examples!

  • Sharp, complex crystals of pyrite are piled up over a single, dark brown crystal of sphalerite. The pyrites are really overgrowths of pyrite on pseudomorphs of pyrite after marcasite but the pseudo's are so thickly encrusted with the overgrowth crystals, it is hard to tell. Sphalerite was the ore mineral at the Nanisivik Mine. Looks good.

  • This is a very cool plate of pyrite pseudomorphs after dolomite. The pseudomorphs are very clearly rhombohedra, although it is a little difficult to see them in pictures under a veneer of 2-3mm pyrite crystals. There are some areas of the plate covered with larger striated cubes of pyrite. A couple of lustrous, black sphalerite crystals on one side of the plate. Displays well and looks great!

  • This is a WEIRD one! The specimen consists of kind of a hollow inverted cone of pyrite with sharp, isometric crystal forms protruding here and there. As well, there is a nice pyrite crystal inside the cone! Totally unique!
