This book is the first volume of a new interdisciplinary series on
"Impact Studies". The volumes of this series aim to include all aspects
of research related to impact cratering - geology, geophysics,
paleontology, geochemistry, mineralogy, petrology, planetolgy, etc.
Future volumes will include monographs, field guides, conference
proceedings, etc. All contributions in this book were peer-reviewed to
ensure high scientific quality. The thirteen papers in the present
volume result from a workshop of the European Science Foundation (ESF)
IMPACT programme ("Response of the Earth System to Impact Processes").
This programme is an interdisciplinary effort aimed at understanding
impact processes and their effects on the Earth System, including
environmental, biological, and geological changes, and consequences for
the biodiversity of ecosystems. The goals of the programme, and details
about our activities, can be found on the web at . The IMPACT programme
has currently 15 member nations from allover Europe. The activities of
the programme range from workshops to specific topics regarding impact
cratering, short courses on impact stratigraphy, shock metamorphism,
etc., mobility grants for students and young researchers, development of
teaching aids, and publications. The third IMPACT workshop was held in
Quillan, in the foothills of the French Pyrenees, in September 1999.
