    Suggest you try the test I recommended, by changing the angle of illumination and watching what happens to the colours as you do so

    Most of the specimen are too small to hold and rotate but what I have done is to take a bright light and moved it around to see what happens, the colors don't change, they just go from bright to dim, like in the last two photos below. I have from time to time come across crystals that do appear to have an iridescence spot on them, the texture appears smooth whereas the texture of most of the colors in question appear grainy. The USGS said that there is also a very high amount of aluminum detected in this stone, I'm not sure if that could have anything to do with any of this but when I looked at a piece of aluminum up close, I do see the colors and texture that I see in the photos. I don't have a clue as to where I found this stone, it's just something that I picked up during my travels in the U.S. Navy, my best guess would be somewhere in California.

    These look like high magnification pictures of the same pyrite specimens you showed us earlier

    Yes, this is all about the same pyrite specimen. I had taken several close-up photos under different lighting and would keep seeing lots of different colors. A few years back someone had me contact a Geochemist that has collected and studied pyrite from all over the world, he was a bit stunned by a lot of what I showed him, said that he had never seen anything like this pyrite. There were several metallic elements detected in this pyrite, I was told it could be anyone of them causing the colors, because iridium was detected at such a high level and known for its colorful compounds, I was told that I should start my research with iridium and work out from there. People kept recommending electronic scans but every scan I had done created more questions than answers. The last photo below is an actual xrf analysis that was done on this pyrite, everyone said that this could not be correct, so they calibrated the instrument and still got pretty much the same results. Thanks for all of the good articles, I've learned a great deal on here.

    We did not see any light from any exploding star from 13.7 billion years ago

    You're right, it wasn't an exploding star that they were talking about, was watching a documentary called "The Universe" and they were talking about the farthest light detected by Hubble which was a galaxy about 13 billion light years away from earth, the scientist were saying that 13.7 is just the limit of what our technology can see. In a documentary called "How the Universe Works", they were talking about how the standard candle technique that they use to measure the distant of galaxies and the expansion of space may not be as accurate as thought before. I'm sure that there's much more that went into coming up with that number but I was curious as to how all of this would affect the number 13.7 billion years old.

  4. It is said that the universe is 13.7 billion years old because we have seen light from an exploding star that took place 13.7 billion light years from earth, and it is also said that 13.7 billion years ago the universe was smaller than an atom, so how on earth could anything have been 13.7 billion light years apart? Some scientist say that 13.7 billion light years is the limit of what our technology can see and interpret and that we don't really know the true age of the universe. Isn't giving the universe an age based on the limit of our technology the same thing as standing on a beach back in 1300 AD, looking out on the horizon and saying the earth is flat because that's all we can see?

    Are they especially colourful? I think Ir compounds are mostly oxidation state +3 or +4 and quite a few of them are black or dark brown. But frankly Ir is not an element I know much about. Which salts do you have in mind

    I was trying to make sense of what I was seeing in the photos below, I kept seeing these colors in several of the closeup photos that were taken of crystals. No one could say for sure what was causing this, a high level of iridium was detected in this stone so I was told maybe what I was seeing was being caused by the colorful salts of the iridium in the stone. I can't find anything on colorful salts of iridium, the best info I've come across about colorful salts in minerals is what I've been given on here, so thanks.

    Very pretty pictures.

    Yeah, they are pretty, thanks. I had a lady try to buy some of these photos, she wanted to have posters made for her son's room, I ended up giving her about 20 photos. 

    In the photos below, like above, I just crushed a small amount of pyrite and instead of placing it in an oven, I just let it run its course in a bowl at room temperature and 2 days later this is what was seen on the slide. Those structures in photos 4&5 have been found inside of crystals that I have crushed, I have no ideas as to what these things are, I agree, they look like tiny plants but why would an organic precipitate out of a pyrite acid solution? I don't want to sit here and waste space and time with a host of odd photos so this will be the last but hopefully this helps to show how strange this pyrite is, and I can assure you that it gets much stranger than this.

  7. Both crystals come from the sample in the photos below. When I first came across this stone, I thought that maybe it was sperrylite because of the odd shaped crystals in the matrix but an xrd, Raman and edx analysis all determined that it is indeed pyrite. If you can zoom in, you will notice that all of the crystals appear have different shapes. I was trying to figure out what these patterns were and see if maybe they could help explain anything about the pyrite. The crystals are extremely small, this entire stone is only about 2 inches long so most of the crystals would be measured in millimeters.

    Would that make sense of what you saw?

    I'm no scientist but what you're saying does appear to agree with what I was seeing, and I do think that you're on to something with the dendrites, I have seen them in a number of tests. In the photos below, I crushed a small amount of the pyrite, placed it on a slide and added two drops of HCI and then placed the slide in a warm oven for about ten minutes. I also did the same test but did not place it in an oven and also got loads of dendrite crystals. I have done this same test with other pyrite, and I get nothing close to these results at all.

  9. In this first test I placed a small amount of pyrite in a spoon and heated it on a stove. I got a blue flame and was left with a small amount of reddish material. I placed the reddish material on a slide and added a couple of drops of hydrochloric acid and saw no immediate reaction. When I looked at the solution about an hour later, I saw several tiny, transparent-like flakes. It was 24 hours later before I checked on it again and saw a lot of things that I have no ideal as to what I was looking at.  Photo #1 shows reddish material in acid, photo #2 shows the tiny flakes and the rest shows what happened after 24 hours. I've done a number of acid test on this pyrite and even when you crush it and add acid, there is no fizz, it just creates bubbles, some rise to the top but most will just sink to the bottom of the solutions.

    I am missing something here. Since you are not a biologist, what is importance of a name you like being "official"? I mean, just name it whatever you want, what else is involved?

    As of now no one can even say for sure what this specimen is, I just thought by taking the official route that would help to figure it out. Yes, I can name it myself, but it would be nice to know what it is I'm naming. 

  11. Have an odd piece of pyrite that I was doing some acid testing on, and I've gotten some really strange acid test results. I purchased some other pyrite so I could compare note and the results are a world apart. There is no way I can explain what I saw with words, but I do have pictures, so would it be cool to post and share them on here?

    When the moon first formed it was much closer to Earth.  It had HUGE tidal force on Earth's core.  Could the moon have cranked the Earth's liquid core, like kick starting a motorcycle?  Maybe because of the moon our liquid core was pushed and pulled by the moon over millions of years, before moving so far away as to not have much affect.  Earth's liquid core was supercharged at the start, and that is why we are still protected by a strong-enough magnetic field?

    For what it's worth, I do believe that this could be right. You know, I never really gave much thought about when the moon was a lot closer to Earth but I think you're on to something here.

    But you say these are organic.

    I don't have a clue as to what these things really are, but I will take any info that I can get. I don't want to make this pyrite out to be something that it isn't but, there's a lot of strange things about it, like this little piece of metal. It was found inside of a crystal, folded in half. I was told that it had to be a platinum or silver flake. I came across a scientist at the USGS that was curious about some of this stuff, so I sent this metal and a couple other strange items to be examined. They said that the metal is pure aluminum and that they could not explain this, and the other items could not be identified. I don't want to bore people with this stuff but I'm learning a lot of new stuff here. I have had an edx, xrf, xrd and Raman analysis done on this stone, there has been over 27 different elements detected in this pyrite. I'm learning a lot on here so hopefully I can share more and learn more. Thanks for the article about pyrite wall tube structures, this helps a lot.

    They look like bits of plants or something. Considering the organic origin of these pyrites, I don't think I would find that surprising. Though difficult to confirm of course, in view of the chemical alteration involving in the fossilisation process.

    Because of their metallic look I never thought about organic but that could be right. I don't want to sit here and waste peoples' time with a bunch of strange photos but I'm learning a lot of new stuff here. I'm no scientist so I might be wrong, but it would appear that there is something totally wrong with the chemistry of this pyrite. At the microscopic level this pyrite is just littered with all sorts of strange things, below is a photo and scan results of a tube-like item.

  15. Have a piece of pyrite that is littered with a host of strange microscopic structures, the ones shown here in these photos have been found in a several different configurations. What's really strange about some of these structures is that if you dissolve some of this pyrite in acid, some of these structures will precipitate out of the solution. I have shown these to a number of scientists, but no one can say for sure what they are or why they form in the acid solution.
