jade, serpentine, feldspar/epidote perthites,jaspers and a couple unknowns
 makes me think of the rings on a peacock's tail feathers.
these appear to be limestone/ soft chertish stuff... the blue is exactly the same color as Copper sulfate... found in 2 locations what is going on here?

this one is very dense and the oolites seem to be filled with ?? calcite? can somebody identify it? (black with white spots)  |

what do you think that one with the eye(peacock feather pattern) and those little white with blue rocks are? I am thinking olivine for the peacock one.. it is very crystal-ish like quartzite, but it isn't quartzite... more gemmy... might even polish... odd stuff.
thinking the blue stuff came in contact with copper dust of some sort and when they got wet and it oxidized... the blue showed up???
Somebody out there must have more of a clue than I? last one seems to be partially silicate basalt with oolites. Don't know if it would tumble but I bet it would polish.

Regarding your "peacock" stone, I'd guess Olivine with some sort of Pyroxene. By the shape of the stubby black crystals, probably Augite.

I'd say chrysocolla on those white\blue ones. According to mindat.org the mineral is listed on the Huron River. Post some closer shots if you can snowmom. Cheers, Roland |

For some reason, I imagine you yelling, "Oh goodie!" every time you pick up a rock. Your enthusiasm is awesome and contagious. |

A very rock intelligent friend (Frank - lithicbeads) from the lap forum delighted me with a visit yesterday and I so wanted to trade brains with him. He taught me a LOT and if my memory was just a little bit better I would be able to say that I learned a lot. I do remember a little bit of what he told me about one of your rocks. The black rock with a greenish tint to part of it (50 -50 mix on the surface) is a basalt from the bottom of a basalt layer. The reason for it's density and heavier SG is because stuff (  ) from the upper layer of the basalt vein leached down to the lower area of the vein and was stuck there unable to pass down and out for some reason beyond my memory. Because the totally black stone is so similar to the greenish one my guess would be that the same thing happened with it but there was nothing in the basalt vein to give it the greenish color. We had way too much information to exchange for what little time we had so many things did not get discussed or was passed over quickly. A week probably would not have been enough time to cover even a small portion of what he could teach me but I was really happy for getting what little time we had. One more thing off the list snowmom. Slowly but surely. Jim |

BTW Even though it is basalt it is a very dense basalt so it should take a very high polish. I have a small thin slab that I am going to put in the lineup for polishing so in another three to six months I should have proof. Way too many projects going at the same time so I am having trouble finishing anything.

Jim/Deb, Ironically, if we are talking about the same black rock (Deb sent me one too), I had a friend independently come up with the basalt with some sort of tiny inclusion crystal ID. I would have responded earlier but realized the concordance when I received a note from Deb. I've worked a bit at polishing it and to date not brought it to far, but it really changes its tone, texture when moving even from the 220 to 280 or 600 grit wheels. Cheers, Tom

The white/light greenish blue looks to me like amazonite

The oolites one looks a little like a cab that I posted a while ago that Rockoonz identified a crinoid.  Rich |
