A couple more super duper close ups of the same mm. This one is very fresh, it’s super black and shiny.

Here’s one I just pulled out at random to image. I need to do that more often. :)

Here’s some zoomed in elemental mapping of a couple mms I had polished a few years ago. It might be hard to read but each image is specifically picking out a certain element and the brighter the coloring in a certain area the more of that element there is.

Here’s the weathered v-type from a while ago. Last SEM image for a while then I’ll get back to color. :)

Another I-type for the collection. This one has a somewhat large Iridium/platinum bead. Hard to imagine just a few years ago I thought I would never find any of these and now I have over a dozen.

Here’s another one of the mms I brought into SEM. Looks like there used to be a bead on the little bridge area but it has since disappeared :)

Back at the lab again… finally. What a great group of humans that work at Macalester college. I learned so much today! More cool mms to come next week. Until then.. happy thanksgiving!

Two close up SEM images of a polished mm. I think I was a little careless and didn’t wipe my finger oils off of this sample.

You haven’t seen these yet? I kind of became obsessed with polishing them.

I need to post more here. But for now I will make it up by sharing a photo of some micrometeorites that have been polished on both ends thin enough to allow light to pass through. :)

This is what I affectionately call a “super duper close up” :)

Here’s a micrometeorite resting on the screen of my phone:)

I know exactly what you’re talking about. There is a company in Minneapolis (where I’m from) that makes them.

A micrometeorite on my fingertip.
