Yes, of course there are aluminous rocks in Canada. What is more important is the location. Are there the right conditions present at this locality to result in zunyite. The "Silverstone" lo ... | |

The whole thing is suspect. I have never heard of a Silverstone locality. I don't know ALL of the localities, though. Zunyite is not listed in the "Catalogue of Canadian Minerals". The asso ... | |

Tracy lived very close to me and I was fortunate to visit with her often. We shared suppers a number of times per year for many years and shared mineralogical discussions and life stories. I will miss ... | |

I concur with John S. White. At the suggestion of John, I started reading Arthur Montgomery's "Reminiscences of a Mineralogist" and quickly read it cover to cover. I'll probably read it agai ... | |

I bow to your knowledge of Moroccan minerals and localities. Still those were very similar specimens (no copper secondaries that I noticed) and people should be aware of it and the possibility that su ... | |

Hi Tomek et al, I guess I’ll never know if it is the exact find but it looks the same. I examined all the specimens closely. All were specimens for sale from Moroccans, during Tucson, 2020. As I said, ... | |

Hello All, I have never had any doubts about the natural nature of the gold crystals from this locality. They are natural and I am glad to see the above detailed analytical work. However, I have seen ... | |

I'm sure you have noted that the pyrite crystals at Nanisivik are mostly combinations of various isometric forms which vary in dominance. in figure 29, the cube dominated but you will also see dodecah ... | |

I was referring to the furthest right pyrite on the right of the specimen. Figure 29, is, in fact, very thick overgrowths on a former pseudomorph. DKJ

Hello Russ,
The pyrites are usually very bizarre and there are good reasons for it. It is not a simple concept. Thousands of unusual pyrites have come from the Nanisivik Mine. The initial iron sul ... |

Hi Olivier, The article Jordi linked you to is a very good summary. I don't know how worried you are about this but, practically speaking, there is not much to worry about. I have been collecting min ... | |

If that piece of quartz is setting the metal detector off, there must be something conductive inside it. I suggest hitting it with a hammer to break it and see if there is gold, pyrrhotite or some oth ... | |

Such a terrible event in Lebanon. To compare it with an earthquake is really misleading, though. I have no doubt that there was an earthquake equivalent of 3.3-4.0 or so. This would only account for s ... | |

Here is a mineral specimen disguised as a fossil. A gastropod, I think. It is as thin as an eggshell and totally composed of tiny calcite or dolomite crystals. | |
