Dissemination of scientific information to the General Public is essential to help people taking informed decisions in their personal lives, but also a passionate task to make young students and amateurs enjoy the wonders of Geology.
In this section you will find the latest news, media contents and past and future events related to the dissemination of my Science to the general public and peers…

Quantifying early diagenetic transformations in lacustrine carbonates: Insights from laboratory experiments
Ancient and recent terrestrial carbonate-precipitating systems are characterised by a heterogeneous array of deposits volumetrically dominated by calcite whose formation takes place in hydrochemically challenging environments.
While sedimentologists and geochemists acknowledge that early formed carbonate crystals may suffer a range of diagenetic processes, extracting information about the primary hydrochemical conditions triggering micro-crystal growth remains a fundamental question.
Environmental interpretations have been hampered by the fact that calcite morphogenesis results from the complex interaction between different physico-chemical and biological parameters which often act simultaneously (e.g., carbonate mineral supersaturation, Mg/Ca ratio of the parental fluid, organic and inorganic additives).
To try to experimentally quantify the sedimentological causes of calcite morphogenesis, a laboratory approach yielding a first attempt at a calcite growth-form phase diagram for alkaline, saline lake settings is presented here. The purpose was to relate specific hydrogeochemically common contexts (variations in calcite supersaturation level, and microbial EPS concentration) to typical calcite precipitates observed in nature.
By exploring how hydrochemical variations of the parental fluid impact non-skeletal calcite precipitate morphology, we can better constrain the nature of the recent and/or ancient fluids driving petrographical changes during eo- to telodiagenetic processes.

A window to the Pyrenees 237 million years ago…
Researchers from Institut Català de Paleontologia (ICP), Universitat Autònoma de Barcelona (UAB), and the Universitat de Barcelona (UB) have just published an article in Journal of Paleontology where they describe more than 450 species of fossils corresponding to the limit of the Upper Middle Triassic (237 to 240 million years ago).
The specimens come from Oden, a small locality in the Eastern Pyrenees. During the Middle Triassic, this region was an extensive shallow and warm marine coastal setting where muddy carbonates deposited below the fair-weather wave base. The study has revealed that fish were the most abundant group living there, along with species that could be new to science.

Approaching young students to the wonders of Paleontology…
The Summer Workshop ‘Argó Programme’ is organised by the Univesitat Autònoma de Barcelona (UAB) and the ICE every year. Bachelor students have a hands-on experience within the University environment and a better idea about what researchers do in their everyday.
They are introduced into the wonders of Geology and Palentology in a fresh and funny way with the support of University Lecturers who guide them at all times. In this way, students are better informed about future career perspectives while they discover how useful is Geology for our Society.
Future editions will address the importance of understanding the causes and consequences of Climate Change and how Geologists are key players to tackle the future challenges about energy and climate management.
