Field trip to Aqua de Ney

Field trip to Aqua de Ney

From 8th-14th August we carried out a field trip to Aqua de Ney Spring , an unusual spring in northern California. Aqua de Ney has the highest reported silica concentration (>4000 pm) and pH value (~11.9) in a natural spring. We collected water from these springs, measured in situ the pH and ex-situ silica concentration. Then, we performed experiments with these waters finding that they react with metals to form silica biomorphs and silica gardens (metal…

Summary of main achievements (August 2014-January 2017)

Summary of main achievements (August 2014-January 2017)

Our project is based on the interaction of two main research lines: 1) The fundamental understanding of the phenomenon of mineral self-assembly and, 2) Its relevance to reveal the transition from non-life to life during the Early Earth. We have made the following progress in both fields: Successful field trips to Aqua de Ney alkaline waters (California), Oman ophiolites and their alkaline springs, Dallol hydrothermal system in Ethiopia, and alkaline lakes in the Southern Rift…

New paper on mineral self-organization, life detection and origin of life

New paper on mineral self-organization, life detection and origin of life

Our last paper on mineral self-organization, life detection and origin of life has just been published in Science Advances: http://advances.sciencemag.org/content/3/3/e1602285.full. This work is one of the dreams of my life as a scientist. For at least 20 years, I have identified the rare and remote places on the planet where there are silica-rich alkaline waters with which I could do the experiments to produce biomorphs. Thus far, without the help of Prometheus, I had not…

Field trip to Oman

Field trip to Oman

This has been the first field study of my Prometheus project. A week-long campaign searching for alkaline water sources in remote parts of the Sultanate of Oman. The trip was organized by my friend and colleague from the University of Bremen, Professor Wolfgang Bach. In this country of the Arabian Peninsula the rocks of the deep mantle of the planet emerge to the surface moved by forces derived from the pushes of the tectonic plates…

De la rosa y el cristal

Vivo en Granada, la ciudad de luces y aguas en la que nació Federico García Lorca. Cada día recorro las mismas calles, bebo las mismas aguas y doy sombra a las mismas luces que iluminaron al poeta. Voy con frecuencia a la casa en que nació y a las casas en que vivió. Lo hago cuando acompaño a los amigos que me visitan, a los que también muestro en Víznar el barranco en el que…

Gan Zhang

I am a chemist from China. I joined the Prof. Juan Manuel García Ruiz’s group in 2010 when I started the master and PhD study in Crystallization and Crystallography, and received the PhD title in 2015. My research in the group towards the polymorphic and morphological control of the crystallization of calcium carbonate as well as the hydrate forms in alkaline silica-rich media, to explore the morphogenetic mechanism of silica biomorphs. My work is strongly…
