Was wondering if anyone has seen this type of rock/mineral before. Not sure what it is, it's a very dark black, very heavy, seems to have some type of crystalline structure.
Yes, I had the impression it could be something of sorts. I found it very deep in the field, nowhere near any roads. But it could very well brought there to level the ground. Thanks
In addition to slag it could possibly be black sphalerite or cassiterite. If I name every black mineral I will eventually be right. Google black minerals.
