Self-organized banded sphalerite and branching galena in the Pine Point
Botryoidal arrays of banded-acicular sphalerite are intergrown with dendritic and branching galena at the Pine Point deposit, Northwest Territories. Scanning electron microscope (SEM) and electron-microprobe analyses (EMP) demonstrate that the banding in sphalerite is due to an alternation in Fe and Zn content.
