<p>[QUOTE=&quot;SPP Ottawa, post: 1852007, member: 39508&quot;]Some bright and shiny stuff (not the coins). This is high grade Pb-Zn ore from the former Pine Point mine, Northwest Territories. The shiny grey stuff is galena and the brown stuff is sphalerite. Canadian loon dollar for scale.</p><p><br /></p><p>[ATTACH=full]309589[/ATTACH] </p><p><br /></p><p>A very fascinating form of sphalerite mineralization. The concentric circular forms and arcuate bands you see are botryoidal sphalerite.</p><p><br /></p><p>[ATTACH=full]309590[/ATTACH]&nbsp; </p><p><br /></p><p>Honey-brown sphalerite crystals, which formed on saddle dolomite. This sample currently is on display in my office now.</p><p><br /></p><p>[ATTACH=full]309591[/ATTACH][/QUOTE]</p><p><br /></p>
