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 lustrous specimen of pyrite crystals with pseudomorphs of pyrite after marcasite scattered around the top of the pyrite. These pseudomorphs are odd in that they are ON the pyrite whereas it is usually the other way around, at Nanisivik. The pseudo's are extremely sharp twins of marcasite. Some are damaged but most are not. Interesting piece!

  • An excellent pyrite after marcasite pseudomorph showing the bladed habit and an oriented mosaic of pyrite overgrowths. Looks great.

  • 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 specimen is a cluster of black sphalerite crystals with a partial shroud of dolomite crystals and peppered with tiny marcasite ands pyrite crystals. Sphalerite was the ore mineral at Nanisivik Mine and this is an excellent example from there.

  • A spiffy looking bladed pyrite pseudomorph after marcasite wit ha fine-grained, oriented pyrite overgrowth that is nicely accented by a few small calcite crystals and a little dolomite on the front. Nice specimen.

  • 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!

  • The Nanisivik Mine was a zinc mine that operated in the Arctic for many years. At one time it was the second most northern base metal mine in the world. Way up there! It was famous for the peculiar pseudomorphs of pyrite after marcasite, extra peculiar because of oriented overgrowths of pyrite ON the pseudomorphs. Here is a very good example! s
