Dear All: Every Thursday I post a thin section image (plane light and/or cross polars; backscatter image) and caption. These have proved to be popular. In my last call for contributions I received quite a few - thank you to all who contributed. But now I am running low and would appreciate your contributions. An image or two and a short caption is all that is needed. The image could be published or unpublished. Thin sections with more of a story could be developed into a #MineralMonday post. Please send your contributions to akoziol1@udayton.edu. Thank you.
