This book provides a general introduction to impact stratigraphy, with
emphasis on the recognition of distal impact ejecta in the field, by
focusing on the impactoclastic layers of the Umbria-Marche sequence in
Central Italy, with an almost perfect stratigraphic record over the last
200 Million years. A general introduction to impact cratering and a
discussion of distal ejecta and impact layers around the world is
followed by a detailed description of the record of the impact of
extraterrestrial bodies in sediments of the Umbria-Marche Apennines. The
volume is of interest to a diverse audience in the geological and
planetary sciences, ranging from (upper) undergraduate to research
level. This book can also be used by students and researchers as a field
guide to some of the most important Italian impact layers.
