This month our image is of an 82g part-slice of the H5 chondrite El Hammami. Approximately 240kg of the fresh looking stones were found in 1997. Our image appears courtesy of Mike Simms. Click here to view the image in the Gallery.

I had reason to get my petrographic scope out, so thought I'd add a few pictures of my El Hammami thin section here. The section is incorrectly ground and is too thin on one edge so the xpol colours are either missing or wrong, but some nice features anyway:
