🔎 UNIDENTIFIED Any idea what this rock is?

Any idea what kinda rock this is? Has a metallic blue shine to it. I could fill a dump truck with it so I’m guessing not rare. Just hadn’t seen it before. Found in southern part of Quachita mtns in SW Arkansas.

You need to include the area that it was found in. Different minerals are found in different areas.

To me it looks like some type of chert, but then again I don't know
diddly about rocks.
