To reserve a date just let us know. Thank you in advance :)

This is a sweet meteorite slice with a fully crusted rim, packed to the gills with pretty, well defined chondrules and a sparse matrix with traces of altered metal. This is a favorite in my collection because contrary to a stereotypical iron meteorite specimen the general population may think of, such as a Sikhote Alin loaded with regmaglypts and steely black exterior, in reality someone experienced may look at this stony meteorite with its well defined chondrules and perhaps have alot more appreciation and familiarity if stony's are your thing. (I'm not knocking Sikhotes, they are my favorite irons).

When I think of the vastness of space and the time associated with the formation of primitive type meteorites, this idea for me is the ultimate amplitude of awareness relating to our own insignificance in this universal time table. To think some of the components of this meteorite formed at a time when our solar system and our sun didn't even exist is an overwhelming reality. This meteorite might as well be Alpha Centuri compared to our solar system, yet it's likely ~just~ accumulated microscopic molten particles created by such a star that's so common in our vast universe, and yet so rare to behold on our tiny planet.

Generally, this is the way I feel while holding these precious intergalactic encyclopedias. To hold a meteorite that perhaps has been booted from the asteroid belt between Mars and Jupiter by a collision or gravitational pull and with a somewhat random trajectory may have even taken a close encounter sling shot lap around the sun before colliding with a Malibu in NY is just absolutely stunning for me. I'm hooked for life.

A quick explanation of the images. The first amplifies the contrast and better reveals the different chondrule types throughout. The second is a regular picture. The third is to highlight the tiny metal content that's visible while illuminated at a right angle, and the last is one I goofed around with that I think you might appreciate because it's basically a negative revealing all the individual inclusions plainly.

I really like your enthusiasm for meteorites Stephen. I share in that also. You have a very nice chondrite slice there. Thanks for sharing the pictures and the write-up.
