Stu, despite his better judgement, has leant me his fragments of the Martian Zagami Meteorite...

I've promised to not eat it, or use it to fertilise geraniums...and I've tried to photograph it as well.

Scanning at 2400dpi was quite good (an excellent way of documenting 'thin' things) and using my Sigma 17-70mm lens..backwards...gave good macro

I can almost convince myself of some olivine grains in there if I stretch the imagery a little.

At something like $3200/gramme, this stuff is valuable. It's a tiny tiny hundredths of gram I'd say - but still about 140x more valuable than gold.

I'm no authority, but I have looked at some grain mounts in my time. Some of those little greenish grains could be olivine, as you suspected. I see a few whitish rectangular grains that could be feldspar. Some of the dark rectangular grains might be a type of pyroxene.

Mostly it's pretty cool that you have/had in your possession something that was once part of Mars.
