jordi Posted October 7, 2018 Author Share Posted October 7, 2018 Little metal spheres are perfect, but not the big ones. Quote Link to comment Share on other sites More sharing options...

bc5391 Posted October 7, 2018 Share Posted October 7, 2018 Twink the meteorite lady here in Tucson told me the easy way to identify a meteorite. you need to polish it and look for the nickel spots. several youtube videos can show you how to polish a rock without lapindary equip.

Lunar meteorites for the most part are not magnetic and contain no or very little metal. Quote Link to comment Share on other sites More sharing options...

Great advice from Twink the meteorite lady! You should grind a "window" in any rock you suspect of being a meteorite. it will teach you a whole lot about rocks as well as meteorites. The outside of a meteorite often has a glaze or fusion crust. The outside of terrestrial rocks are often oxidized or otherwise altered. You need to grind and polish a spot on the rock deep enough to expose the unweathered interior. It is a volcanic rock with inclusions IMHO. But grind a window anyway. At the very least you will learn how to do it and what the rock looks like on the inside. Then go back a few threads and take a look at what a meteorite actually looks like on the inside. Compare and contrast. Quote Link to comment Share on other sites More sharing options...
jordi Posted October 8, 2018 Author Share Posted October 8, 2018 Thank you for the answers How do you explain the "vegetal coal", in terrestrial rocks? I can erode it with my nail... It must be slag or simmilar... Quote Link to comment Share on other sites More sharing options...
Mikestang Posted October 8, 2018 Share Posted October 8, 2018 Clasts in lunar meteorites/breccia are very angular as there is nothing to erode them smooth on the moon. All of the clasts in your rock are well-rounded. Quote Link to comment Share on other sites More sharing options...
