Chillytay Posted January 16, 2020 Share Posted January 16, 2020 Just curious if anyone could help indentify this rock a field hunting find from couple years ago this is extremely heavy for size I have a strong earth magnet square hung from ceiling on a string and rock pulls the magnet towards it but not fast the magnet does not snap onto rock 60088651863__7FD80C2D-0203-4808-B274-77FCD2AA0AED.MOV Quote Link to comment Share on other sites More sharing options...
Morlock Posted January 16, 2020 Share Posted January 16, 2020 Did you do a streak test on it? Looks like magnetite which will give a grey streak. 1 Quote Link to comment Share on other sites More sharing options...
Chillytay Posted January 16, 2020 Author Share Posted January 16, 2020 Curious about these as well. They are very responsive to magnet thank you for any help Quote Link to comment Share on other sites More sharing options...

When test with black it is a black streak silver underneath don’t see anything from streak Quote Link to comment Share on other sites More sharing options...
Chillytay Posted January 16, 2020 Author Share Posted January 16, 2020 Not sure about magnetite it barely makes magnetic react and magnet does not stick to it Quote Link to comment Share on other sites More sharing options...

Just scrap iron from many years ago. 1 Quote Link to comment Share on other sites More sharing options...

Smear shavings onto a piece of white paper and note the color. If its magnetite, the powder will be dark gray to black. Quote Link to comment Share on other sites More sharing options...

I will try file but what I’m meant as far as streak test was with the part black it is black streak where I sanded down to silver i am not getting a streak Quote Link to comment Share on other sites More sharing options...
Chillytay Posted January 16, 2020 Author Share Posted January 16, 2020 Don’t have a real good file but what I used is showing similar I do see little black when I hit the black areas but the silver doesn’t seem to show anything and even the black when I smear with finger I don’t see any distinctive color Quote Link to comment Share on other sites More sharing options...
Chillytay Posted January 16, 2020 Author Share Posted January 16, 2020 If it was magnetite wouldn’t magnet stick to the rock even the square earth magnet doesn’t stick and that sticks strongly to anything possible I actually have to close my hand when I hold it so it doesn’t attract to things and pulling off of something It takes a slide off Quote Link to comment Share on other sites More sharing options...
Chillytay Posted January 16, 2020 Author Share Posted January 16, 2020 I see similarities to magnetite lodestone but they state that it acts like a magnet and I tried with nails, bolts, screws and other types metal nothing sticks to it and like I said not even a magnet sticks to it it only pulls magnet towards it But does not stick and even regular refrigerator magnets are even less responsive to it also it does show that the silver underneath the black shell would leave black streak and it is not Quote Link to comment Share on other sites More sharing options...
Bedrock Bob Posted January 16, 2020 Share Posted January 16, 2020 It is mineral iron. You are misinterpreting the information for magnetite. It is not always magnetic nor does it always show magnetism. You are also mistaking sub-metallic luster for metallic luster. What you have is simply not metallic. It is sub metallic terrestrial iron mineral. A proper streak test will reveal a light grey or pink streak. The window will show a sub metallic luster. This indicates a terrestrial iron mineral either magnetite or hematite. Learn the basic field tests and how to interpret them correctly. You will never mistake mineral for free metallic iron again.

Thanks bedrock bob well considering that some of your response doesn’t make sense to me shows me that learning the basics is right and that does make sense to me. 1 Quote Link to comment Share on other sites More sharing options...
