Marcasite
An example of the element Iron

Sample Image
Iron Marcasite
Marcasite.
The tag that came with sample reads as follows:
Marcasite
A dimorph of iron pyrite from Montezuma Co., Colorado
This specimen was found in the tailings of the THUNDER mine north of Mancos, Colorado. Iron Pyrite is FeS2 and so is Marcasite. However it is a separate mineral and often found in gold deposits.
I traded this sample for a few of my strange copper nodules.
