A closer image of the leading side.  I have noticed a few signs of rust pockets so about to treat it but wanted to take a few images before it was too shiny.    I think they are called "oriented" when formed this way?

Very nice sample, Scott.

 

I'm not into this whole area of meteorite collection etc.,, but you say that you will be treating the 'rust pockets'. I'm wondering, if doing so is recommended/allowed, and so take away from its originality (that is, let nature have its way), or, indeed, devalue the specimen, too.

 

John

Sikhote-Alins are one of the few irons that actually have fusion crust remaining, as does this one. Inhibiting further rust formation will prevent degradation of that crust. Doing so will preserve its original condition, not 'take away' from it. G-96 gun oil is the favorite among many collectors.

Thanks, Lee.  G-96 is exactly what I am using for this one.  

 

In general, I try to leave my specimens alone (aka as-is) being that I store them the best I can in a sealed humidity controlled environment but a few of my irons are just inherent to show some rust intrusion over time.  Out of my collection, there are only a few which I keep a closer eye on and do occasional treatment with gun oil or WD40.   

 

John, you of all people should definitely treat yourself to at least one lunar meteorite "from the near side Moon!" wink.gif

Thanks, Lee, for getting in on the conversation concerning the 'rust' issue. I really wasn't aware of how such things are handled, as I kinda was thinking along lines of, say, having an antique piece of furniture, or sculpture, where the patina adds to the originality when left alone.

 

Scott, that made me laugh out loud...I'll have to get in touch with someone from NASA to send me some free samples lol.gif lol.gif lol.gif
