This international workshop funded by the BQR program of the Côte d’Azur Observatory, with the support of the Center for Lunar and Asteroid Surface Science (CLASS, a node of NASA SSERVI), is aimed to promote discussions on:

  • how spectral properties obtained by ground based observations of primitive asteroids relate to primitive meteorite properties,
  • how fluid-assisted thermal processes and aqueous alteration have modified the primary chondritic components (Calcium-Aluminium refractory Inclusions, chondrules and matrices) in carbonaceous chondrites,
  • how these secondary phase transformations may shed light on parent body conditions (fluid and rock chemical compositions, redox, pressure, temperature, fluid/rock ratio) and internal dynamics (e.g., P-T-X paths, by analogy to Earth metamorphic rocks),
  • how these new mineralogical data can help us to provide new guidelines for the search of primitive asteroids and the parent bodies of carbonaceous chondrites by remote spectral observations.

In order to trigger as much as possible exchanges and discussions and foster possible collaborations, the workshop will gather only a restricted number of invited colleagues from different fields including cosmochemistry, astrophysics, planetary and asteroid science and geology.

The workshop will be held at la Citadelle de Villefranche Sur Mer near Nice in France (see venue), the week after the workshop on "Accretion and Early differentiation of the Earth and terrestrial planets" that will take place on May 26-31, at the Maison du Séminaire in Nice.

There are no registration fees and the organization will offer the three lunches.
