  • The top and part of the bottom, in several places, of this fragment of diabase are slathered with leaves of native silver. The leaves are part of what once was a continuous leaves that were seams in the diabase that were ripped apart when cracked open. The Nipissing Diabase Sill is generally regarded as being related to the genesis of the Cobalt silver veins. Silver veins are always in close proximity to the Diabase sill but we don't often find it IN the diabase. Here is an excellent example of silver in Nipissing Diabase.

The silver is mostly present as clots and veinlets with just a little crystallized silver. The specimen is sawn on one side to show the mineralogical textures very well. The reverse shows just native silver protruding from the dolomite and a greenish secondary product of the nickel minerals. Beautiful specimen from an unusual location!

As well, there are lots of much courser veinlets of native silver, as well. Interestingly, there are a couple of blobs of colourless quartz, that have fractured differently than the dolomite and have more silver veinlets in them and no dendritic. Very interesting!
