    Postimage.org / gallery - CIMG4117, CIMG4118, CIMG4119, CIMG4120







    It weighs about 92 pounds and is about the volume of two basketballs, its either non-magnetic or very weakly so, I originally picked it up because it looked out of place compared to the surrounding geological formations, and had what appeared to be fusion crust, however not being magnetic greatly reduced the possibility of it being a meteorite, however based on the appearance and some of its qualities I think it may be hematite. I could chip some off and that would help solve it but, I figured I'd let everyone ponder this one over before break it open.

    Any input is greatly appreciated, I'm a history guy so I know my analysis is at best that of a journeyman, so I thought I'd seek wisdom elsewhere
    Thanks

    I don't do long distance rock identification any more.

    The Institute of Meteorics at the University of New Mexico has a short identification guide you might find helpful.

    Could be a geode.

    if its heavy that indicates it is totally solid, and this the opposite of a geode.

    What environment was it found in and what was the surrounding geology?

    These have all been great posts, very helpful and things I haven't considered. The rock was found as part of a small fireplace all the over rocks looked like common river stones leftover from glacial deposits, non of which were of similar size or composition. it is safe to say the rock was removed from any helpful surroundings.

    Was it in an area that had a lot of glacial activity? And if so Were they montain or continental glaciers?

    That being the case, you have to consider that it quite possibly could be a glacially transported rock from the central Canadian shield. The are notable cases of rocks and fossil found hundreds of miles from the source strata. Here in WA state we have found Ammonites near Seattle that came from Southern British Columbia and Zeolites from Northern Central British Columbia are found in the Columbia River near Hanford nuclear Reservoir.

    I think it is a rock, or possibly a troll egg.

    I found a similar, very heavy rock in Minnesota. Small, strong magnets stick to it. A magnet on a string is a great way to test for iron.

    Some geologists thought that perhaps a glacier brought it down from michigan.

    Michigan or for that matter Northern Minn are both probable, hence the name "iron range". There are large iron deposits in the areas there.

    Yes we do have our own iron range. The geologist had reason to believe that my rock came from the northeast instead of due north.
