larense Posted July 19, 2007 Share Posted July 19, 2007 Hola to all forists. In a small meteorite stone we bought, there is a yellowish grain embedded in a pit on the surface of it. We thought it could be a sand grain that sticked after the fall, but we tried to remove it with a point of a needle and it is strongly attached to the meteorite. ¿ Could it be an exposed chondrule ?. We are sending a macro picture and any opinion is wellcome. Hasta la vista, larense Quote Link to comment Share on other sites More sharing options...
Guest EARL Posted July 19, 2007 Share Posted July 19, 2007 Could be, Hard to say from a photo. You might consider cutting a window into it, so you can see what's inside. Quote Link to comment Share on other sites More sharing options...
Mr Hunter Man Posted July 20, 2007 Share Posted July 20, 2007 Larense, It looks like a terrestrial sand grain that was fused to the chondrite during entry to Earth. I have had meteorites with sand grains embedded into them, however I have been able to get them out, some easier that others.

larense Posted July 20, 2007 Author Share Posted July 20, 2007 Hola Joe. Yes we have as well cosmic stones with superficial cracks full of sand grains, but this one is in a pit ......we tried hard to pull it out but failed. Perhaps we will try to put some drop of an acid to losen any caliche cementing of it to the meteorite surface...in case it is a sand grain ¿ What do you think ? hasta la vista, amigo larense Quote Link to comment Share on other sites More sharing options...
larense Posted July 20, 2007 Author Share Posted July 20, 2007 Hi amigos. From other forum, a forist wrote : ...... " I'm told that as part of the weathering process an iron oxide product actually produces a "coating" in which sand grains can become embedded ". Probably he is talking about " dessert varnish " and in that case, the grain should have also been covered with the oxide film..... but it is not....and we can not imagine a sand grain going embedded in a fusion crust (indentation pit )....as we wrote before....we have some cosmic stones that have cracks on their exterior and those sites can more easily lodge sand grains. Look at the picture. Hasta la vista, larense Quote Link to comment Share on other sites More sharing options...

Guest EARL Posted July 20, 2007 Share Posted July 20, 2007 larense What is the classification of your meteorite? Is it an iron, stony-iron or chondrite? Quote Link to comment Share on other sites More sharing options...

larense Posted July 21, 2007 Author Share Posted July 21, 2007 Hola forists.
