2001: THE CRYSTAL MONOLITH
2001: IL MONOLITO DI CRISTALLO by Juan Manuel García-Ruiz Humans are fascinated by crystals since the primitive era, and even today they are considered to have a mysterious power. Available the article in pdf here: 2020 JuanMa Garcia-Ruiz RUIZ_p.98-101 2001 Il monolitoL

Rouillard, J., García-Ruiz, J. M., Kah, L., Gérard, E., Barrier, L., Nabhan, S., … & van Zuilen, M. A. (2019). Identifying microbial life in rocks: Insights from population morphometry. Geobiology. Download here: https://onlinelibrary.wiley.com/doi/full/10.1111/gbi.12377 The identification of cellular life in the rock record is problematic, since microbial life forms, and particularly bacteria, lack sufficient morphologic complexity to be effectively distinguished from certain abiogenic features in rocks. Examples include organic pore‐fillings, hydrocarbon‐containing fluid inclusions, organic coatings on exfoliated…
Read MoreField trip to Ronda peridotites (Malaga, Spain)
A second field trip to the Ronda peridotites was carried out on the 2-5th May 2016 in order to investigate in more details the geochemistry of the alkaline waters and the occurring mineralization. We collected several water and solid samples to examine the chemical profiles of river and hyperalkaline spring waters, as well as the phases and textures of the present carbonate minerals. Finally, we conducted an additional field trip to the alkaline springs in…
Read MoreA big ”Thank you” to all the ERC officials from the members of the Prometheus project
ERC (European Research Council) projects have earned an excellent reputation within and outside Europe. They are difficult projects to obtain, but once you get one, you can understand that they are designed specifically for the leading scientists of each project and the people who are going to carry them out. It is evident that the ERC officials are there to help and facilitate the research under a strict framework of legality. From the evaluation to…

The discharge of these waters forms complex alkaline pool networks, in which mineral precipitation is triggered by mixing, evaporation, and uptake…

Ronda waters can be classified into hyperalkaline fluids and river waters that are broadly similar to Ca2+–OH– and Mg2+–HCO3– water types described in…

Opel, J., Brunner, J., Zimmermanns, R., Steegmans, T., Sturm, E., Kellermeier, M., … & García‐Ruiz, J. M. (2019). Symbiosis of Silica Biomorphs and Magnetite Mesocrystals. Advanced Functional Materials, 29(37), 1902047. Download here: https://onlinelibrary.wiley.com/doi/epdf/10.1002/adfm.201902047 Silica biomorphs are extraordinary inorganic superstructures formed via autocatalytic co‐precipitation and bottom‐up self‐assembly of alkaline‐earth carbonates and silica. However, they show no inherent functionality except for their striking textural motifs and curved morphologies. This work presents strategies to magnetize silica biomorphs, thus creating thermally…

Download here: https://www.mdpi.com/2073-4352/9/3/157 The formation of a polymer protection layer around fragile mineral architectures ensures that structures stay intact even after treatments that would normally destroy them going along with a total loss of textural information. Here we present a strategy to preserve the shape of silica-carbonate biomorphs with polymers. This method converts…
