Impact Tectonics

Christian Koeberl, Herbert Henkel9783540241812, 3-540-24181-7

This volume is the 8th in a series of impact books resulting from the activities of the scientific program “Response of the Earth System to Impact Processes” (IMPACT), by the European Science Foundation. The book resulted from an international meeting at Mora, Sweden, which was held as part of the IMPACT program. The papers cover various structural geologic, geochemical, and geophysical topics on research of asteroid impact structures on Earth and Mars.
