This tool is a standalone application developed by Ekaterina (Katia) Ossetchkina, 2021. This digital thin-section was created as an educational tool, part of the paper Tapas de sílice – a smörgåsbord of reactive mineralogies and textures, 2021, authored by Lucas Herzog Bromerchenkel, Oleksiy Chernoloz, Pengfei Zhao, Ekaterina Ossetchkina, and Dr. Karl Peterson.

The sample images shared in this code are the Tapas Silice sand, same as in the original publication.
