 Preliminary results of this project were presented by the lead researcher Thomas Teillet (former KAUST postdoc) at the [[https://www.imageevent.org/|International Meeting for Applied Geoscience and Energy (IMAGE) Conference]] as well as at the [[https://www.sepm.org/mountjoy-2025|Mountjoy Carbonate Conference]], both in August 2025. More information can also be found in a preliminary report in GeoScienceWorld entitled: [[https://pubs.geoscienceworld.org/sepm/books/edited-volume/2828/chapter/153154491/Micritized-Grains-and-Peloids-The-Taphonomic|"Micritized Grains and Peloids: The Taphonomic Adventures of Carbonate Grains in Shallow Marine Settings"]]. Preliminary results of this project were presented by the lead researcher Thomas Teillet (former KAUST postdoc) at the [[https://www.imageevent.org/|International Meeting for Applied Geoscience and Energy (IMAGE) Conference]] as well as at the [[https://www.sepm.org/mountjoy-2025|Mountjoy Carbonate Conference]], both in August 2025.

-KVL's visualization scientist Dr. Ronell Sicat supported Dr. Martinez in pre-processing the TEM scans, testing segmentation methods, and eventually post-processing the segmentation and extracted surfaces in order to get 3D geometries that were suitable for the target simulation software. KVL also provided free access to Avizo software for data visualization, segmentation, and analysis and a powerful workstation with a pen-and-tablet interface that enabled faster manual segmentation of the TEM data. KVL's contribution is acknowledged in the paper.+KVL's visualization scientist Dr. Ronell Sicat supported Dr. Teillet in processing the μCT data using Avizo software, including preprocessing, alignment, segmentation, and analysis, in order to quantify changes in the rock samples over time (see below image).  A full paper is currently underway with a more detailed analysis of the microbial interactions with the rock samples.
