Have you had it tested?Some more photos... Please note any specimens that I intend to either trade or smelt are not of this size. The meteorites I would consider to be refine worthy are about 1mm or smaller in size.
I discovered a gravel heap and it turned out to all be meteorites
Testing is whats needed, I have not seen anything hinting of non terrestrial origin.Stella this is called polymorphism and it is somewhat random.
I agree that samples need to be analyzed from various parties and that's why I was offering samples of 100 grams to anyone who would be interested.Iron pyrite = fools gold
Arsenic = fools iridium
They often walk hand in hand
Arsenic did not fool anyone in old days. Well murder victims can be said to been fooled. (wash your hands)
But today Arsenic can be called fools Iridium due to the belief in technology.
I do not trust tech. I have been driving a boat 800 m (1/2 mile) up on land. That was what the GPS said. If I trusted the GPS I would have run on ground. Now a XRF is programmed for different task. The machine you did your test on is made and programmed for general karat testing of gold. Its simply not made for the kind of test you made. You can probably buy an expensive program for that type of testing but I do not think that is the case. They probably went with the standard program for gold dealers. Ask the manufacture about the thing.
You are not the first nor the last to fall in this trap. The expensive testing tool give a result you accept. We have a tendency to behave like this. Call closest university and tell them you found a gravel pile of meterioites. They probably will hang up. We do not reflect on that. We believe more in the scrap dealers tech than in the professor.
If this pile laying in the old world it can be a more than a 1000 year old dump. In fact it could be an archeological site. Iron pyrite gets rusty by the time in some cases. Thats what I think you have . Rusty pieces of Iron pyrite. In the mineral was also some arsenic.
