Regmaglitch Posted July 20, 2015 Share Posted July 20, 2015 Hi Togba, Not a meteorite. The surface is granular. Ben Quote Link to comment Share on other sites More sharing options...
Mikestang Posted July 20, 2015 Share Posted July 20, 2015 Not a meteorite, just an earth rock with a coating. Quote Link to comment Share on other sites More sharing options...
Josmcclellan Posted August 9, 2015 Share Posted August 9, 2015 (edited) Looks like maybe achondrite middle pic w/possible flow lines on fusion crust. I know most > 97 percent will be magnetic, nongranular,nonporous, etc, but I have seen photos of lunar and achondrites(rare) which do not fall into most categories, (either granular from erosion or chipping, and lunar meteorites with pores in the fusion crust). Only way to tell would be to get an analysis done. Without fusion crust you cannot tell an achondrite from a normal rock without a lab.See here for example.http://www.meteorite-recon.com/en/Meteorite_Mount_Tazerzait.html Edited August 10, 2015 by Josmcclellan Quote Link to comment Share on other sites More sharing options...
