    I have been a rock nut for some time and dismissed this as a meteorite because of the holes but now thinking it could be a Eucrite. It is attracted to a magnet but not strong and is heavy. All the white stuff looks like calcium or some type of crystal. Don't see what could cause the magnet to stick when split apart but what looks like tiny small silver looking specks

    At first look look it seems to be a weathered and water/glacial worn rhyolite or andisite. It does not have any external features one would expect from a meteorite.

    photos 2 and 3 show distinct terrestrial igneous rock form what I can see. What would you be looking for for magnetite, and why?

    Well I did a little research on rhyolite and andisite and found that magnetite is found in them and that is most likely the cause of the magnet attraction. I don't see that on this rock. I do have some rocks with magnetite in them and know what it looks like. I don't see what could be sticking and this whole rock to the dust is attracted. Any other possibilities?

    If paleo is correct then the large white crystals would be feldspar phenocrysts.

    The magnetite would be distributed microscopically throughout the rock and not visible except in the microscope.

    The lineation and apparent flattening of the feldspars could be the result of flow, but I don't rule out this being a schist. It's too worn to make a clear identification.

    I am comfortable, however, that it is not a meteorite.

    I will look into that thanks. Can't blame a guy for asking lol. So do you guys know about copper ore/pebbles. I found three small copper stones or could just be old melted balls of copper. My question is could they be natural here in the yard or more likely man made. Can. Post photos if needed I think. Just wondering. Thanks for your replys

    Without knowing where regionally you are its hard to comment on the nature of the copper stained samples your asking about.
