Is this first picture hematite? Found this near an old iron works in Nj?  The next stone I found in a stream. Thoughts greenish blue color was nice and wondered if anyone could ID and help if this is something I can tumble  |

The first one looks like iron slag to me (always a let down for people who think they found a meteorite).

The second one looks like it could be Unakite.

The second one looks like it could be Unakite. That was one of my thoughts as I was researching. Unakite can be tumbled correct? |

Only reason I wasn’t sure about unakite is I don’t see any pink really. It looks like iron oxide mixed in there to me, but I could be wrong |

Would hematite be common in areas near old iron mines? If hematite is the ore that’s being extracted, then yes. It’s far from the only iron ore, though. |

Depending on where in NJ you found it. The latter one looks a lot like the Coon Creek formation in TN so I am going to say it is a glauconitic mudstone/clay from the cretaceous. check for cretaceous fossils in the area (ammonite, shark teeth, mosasaur bones, turtle shell, gastropods and oysters). should be easily cut with a knife.
If the first rock has a red streak then hematite. Otherwise to dark to tell from the image.
