This volume is the third in a series of impact books resulting from the activities of the scientific programme, Response of the Earth System to Impact Processes (IMPACT), funded by the European Science Foundation. The volume begins with an overview of impact markers in the stratigraphic record, and is followed by three general papers on various aspects of impact cratering, ranging from a suggested nomenclature of impact product to a treatment of the hypothesis that impacts can trigger mantle plumes. Then follow 10 original contributions on various impact deposits in the stratigraphic record, ordered by increasing age, ranging from the Late Eocene Popigai impact crater to the K-T boundary to the J-K boundary and Late Devonian and Ordovician deposits.
