Hi Greg and List, Thanks for bringing up eucrites and howardites. :)
A while back, I was cutting a howardite stone for a friend, and I noticed a big "ball bearing" metal inclusion. It was about 1cm in diameter and it was visible on the surface of the stone, poking through the crust. The majority of the stone showed almost no attraction at all to a magnet, but that "ball bearing" stuck firmly to the magnet. Pure basaltic eucrites typically show no attraction, but some brecciated eucrites do have free metal content. Camel Donga also comes to mind as a eucrite that shows a mild attraction to a magnet. I guess for those looking for a fool-proof magnetic litmus test to seperate the wrongs from the 'rites must always be on their toes - meteorites like to throw us curveballs to keep us honest. :) Best regards, MikeG --------------------------------------------------------------------------------- Galactic Stone & Ironworks - Meteorites & Amber (Michael Gilmer) Website - http://www.galactic-stone.com Facebook - http://www.facebook.com/pages/Galactic-Stone-Ironworks/218849894809686 News Feed - http://www.galactic-stone.com/rss/126516 Twitter - http://twitter.com/galacticstone EOM - http://www.encyclopedia-of-meteorites.com/collection.aspx?id=1564 --------------------------------------------------------------------------------- On 5/24/11, Thunder Stone <stanleygr...@hotmail.com> wrote: > > David/List: > I believe the following meteorites can have no, or negligible magnetic > pull.RumurutiitesHowarditesEucrites - may have slight > pullDiogenitesLunarsAubrites > and perhaps Martian, but they may have a slight attraction > Sounds very interesting > Greg S > > ---------------------------------------- >> Date: Tue, 24 May 2011 11:41:55 -0400 >> From: davidgunn...@fairpoint.net >> To: meteorite-list@meteoritecentral.com >> Subject: [meteorite-list] non-magnetic meteorites? >> >> Hi All, >> >> It's commonly understood that all meteorites are magnetic to varying >> degrees, or so I've read.
