The primordial crust is considered the starting point of planetary evolution, the water and carbon cycles, and the emergence of life. It also plays a crucial role in the evolution of civilization and technology. However, research on the first FELSIC (Si-Al-rich) or continental crust, formed more than 4.0 Gyr ago, is currently at a standstill. The PLANETAFELSIC project aims to find fundamental links between planetary internal dynamics, magmatism, hydrothermal activity, and life. The project will re-examine the role of water in the formation and evolution of the first felsic crust. It will use an interdisciplinary approach including kinetic experiments, geodynamic modeling, and in situ analyses, all based on a solid physicochemical foundation. PLANETAFELSIC implements an interdisciplinary approach, a young international team, a new experimental laboratory and a unique collection of terrestrial zircons and extraterrestrial samples.

Dr. HDR Anastassia Borisova is Senior Scientist (CNRS) at Observatoire Midi-Pyrénées (Laboratory of Géosciences Environnement Toulouse), Toulouse, France. Dr. HDR Borisova was a Postdoctoral Researcher at Université Libre de Bruxelles, Brussels, Belgium; Institut des Sciences de la Terre d'Orléans, Orléans, France; and Observatoire Midi-Pyrénées, Toulouse, France. She was a Ph.D. student at Institute of Geochemistry and Analytical Chemistry, Moscow, Russia, from 1993 to 1997 and a postgraduate student at the Department of Geology, Moscow State University, Moscow, Russia, from 1988 to 1993, specializing in petrology and geochemistry.
In 1998, she received the Ph.D. degree in geochemistry and petrology from Institute of Geochemistry and Analytical Chemistry, Russian Academy of Sciences, Moscow, Russia. Her areas of expertise include experimental petrology, geochemistry of magmatic and hydrothermal processes, thermodynamics and kinetics, origin of magmas and mechanisms of volcanic eruptions, ore deposit formation. In 2015, she received the HDR degree from University of Toulouse (Toulouse, France). Now, she is now working on the ERC ADG PLANETAFELSIC project (2025 - 2030).

Documentary film
“Fragments of a lost world: Tracking down the first continents”
A turning point for the whole planetary evolution, climate and habitability was the onset of felsic (i.e., enriched in Si and Al) or continental crust formation during Hadean eon 4.5 – 4.0 Gyr ago. To date, this onset is traced using natural zircon mineral (ZrSiO4)-bearing rocks, as well as laboratory experiment and modelling. ERC Advanced PLANETAFELSIC project is based on cutting-edge experiments and modelling as well as field data acquisition on natural rock samples to construct a first comprehensive fundamental model of the primordial felsic crust formation and evolution on Earth, and very likely, Mars and Venus.
This film “Fragments of a lost world: Tracking down the first continents” is dedicated to the first scientific expedition to Australia to sample the Hadean zircon-bearing rock collection in collaboration with Curtin University in Australia in the framework of this ERC project directed by Dr. HDR Anastassia Borisova from Observatoire Midi-Pyrenees, Toulouse, France.
